Abstract

DoD is proposing to establish requirements for a comprehensive and scalable assessment mechanism to ensure defense contractors and subcontractors have, as part of the Cybersecurity Maturity Model Certification (CMMC) Program, implemented required security measures to expand application of existing security requirements for Federal Contract Information (FCI) and add new Controlled Unclassified Information (CUI) security requirements for certain priority programs. DoD currently requires covered defense contractors and subcontractors to implement the security protections set forth in the National Institute of Standards and Technology (NIST) Special Publication (SP) 800-171 Rev 2 to provide adequate security for sensitive unclassified DoD information that is processed, stored, or transmitted on contractor information systems and to document their implementation status, including any plans of action for any NIST SP 800-171 Rev 2 requirement not yet implemented, in a System Security Plan (SSP). The CMMC Program provides the Department the mechanism needed to verify that a defense contractor or subcontractor has implemented the security requirements at each CMMC Level and is maintaining that status across the contract period of performance, as required.

Cybersecurity Maturity Model Certification (CMMC) Program

AGENCY: Office of the Department of Defense Chief Information Officer 
(CIO), Department of Defense (DoD).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: DoD is proposing to establish requirements for a comprehensive 
and scalable assessment mechanism to ensure defense contractors and 
subcontractors have, as part of the Cybersecurity Maturity Model 
Certification (CMMC) Program, implemented required security measures to 
expand application of existing security requirements for Federal 
Contract Information (FCI) and add new Controlled Unclassified 
Information (CUI) security requirements for certain priority programs. 
DoD currently requires covered defense contractors and subcontractors 
to implement the security protections set forth in the National 
Institute of Standards and Technology (NIST) Special Publication (SP) 
800-171 Rev 2 to provide adequate security for sensitive unclassified 
DoD information that is processed, stored, or transmitted on contractor 
information systems and to document their implementation status, 
including any plans of action for any NIST SP 800-171 Rev 2 requirement 
not yet implemented, in a System Security Plan (SSP). The CMMC Program 
provides the Department the mechanism needed to verify that a defense 
contractor or subcontractor has implemented the security requirements 
at each CMMC Level and is maintaining that status across the contract 
period of performance, as required.

DATES: Comments must be received by February 26, 2024.

SUPPLEMENTARY INFORMATION: 

History of the Program

    The CMMC Program is designed to verify protection of sensitive 
unclassified information shared between the Department and its 
contractors and subcontractors or generated by the contractors and 
subcontractors. CMMC increases assurance that contractors and 
subcontractors are meeting cybersecurity requirements applying to 
acquisition programs and systems processing CUI.
    The beginnings of CMMC start with the November 2010, Executive 
Order (E.O.) 13556,\1\ Controlled Unclassified Information. The intent 
of this Order was to ``establish an open and uniform program for 
managing [unclassified] information that requires safeguarding or 
dissemination controls.'' Prior to this E.O., more than 100 different 
markings for this information existed across the executive branch. This 
ad hoc, agency-specific approach created inefficiency and confusion, 
led to a patchwork system that failed to adequately safeguard 
information requiring protection, and unnecessarily restricted 
information-sharing.
---------------------------------------------------------------------------

(November 4, 2010).
---------------------------------------------------------------------------

    As a result, the E.O. established the CUI Program to standardize 
the way the executive branch handles information requiring safeguarding 
or dissemination controls (excluding information that is classified 
under E.O. 13526, Classified National Security Information \2\ or any 
predecessor or successor order; or the Atomic Energy Act of 1954,\3\ as 
amended).

---------------------------------------------------------------------------

    In 2019, DoD announced the development of CMMC in order to move 
away from a ``self-attestation'' model of security. It was first 
conceived by the Office of the Under Secretary of Defense for 
Acquisition and Sustainment (OUSD(A&S)) to secure the Defense 
Industrial Base (DIB) sector against evolving cybersecurity threats. In 
September 2020, DoD published an interim rule, Defense Federal 
Acquisition Regulation Supplement (DFARS): Assessing Contractor 
Implementation of Cybersecurity Requirements (DFARS Case 2019-D041),\4\ 
which implemented the DoD's initial vision for the CMMC Program (``CMMC 
1.0'') and outlined the basic features of the framework (tiered model 
of practices and processes, required assessments, and implementation 
through contracts) to protect FCI and CUI. The interim rule became 
effective on 30 November 2020, establishing a five-year phase-in 
period. In response to approximately 750 public comments on the CMMC 
1.0 Program, in March 2021, the Department initiated an internal review 
of CMMC's implementation.
---------------------------------------------------------------------------

    \4\ <a href="https://www.federalregister.gov/documents/2020/09/29/2020-21123/defense-federal-acquisition-regulation-supplement-assessing-contractor-implementation-of">https://www.federalregister.gov/documents/2020/09/29/2020-21123/defense-federal-acquisition-regulation-supplement-assessing-contractor-implementation-of</a>.
---------------------------------------------------------------------------

    In November 2021, the Department announced ``CMMC 2.0,'' an updated 
program structure and requirements designed to achieve the primary 
goals of the internal review:
<bullet> Safeguard sensitive information to enable and protect the 
warfighter
<bullet> Enforce DIB cybersecurity standards to meet evolving threats
<bullet> Ensure accountability while minimizing barriers to compliance 
with DoD requirements
<bullet> Perpetuate a collaborative culture of cybersecurity and cyber 
resilience
<bullet> Maintain public trust through high professional and ethical 
standards
    The CMMC 2.0 Program has three key features:

    <bullet> Tiered Model: CMMC requires companies entrusted with 
national security information to implement cybersecurity standards at 
progressively advanced levels, depending on the type and sensitivity of 
the information. The program also describes the process for requiring 
protection of information flowed down to subcontractors.
    <bullet> Assessment Requirement: CMMC assessments allow the 
Department to verify the implementation of clear cybersecurity 
standards.

[[Page 89059]]

    <bullet> Implementation through Contracts: Once CMMC is fully 
implemented, certain DoD contractors handling sensitive unclassified 
DoD information will be required to achieve a particular CMMC level as 
a condition of contract award.

CMMC 2.0 Overview as Proposed by This Rule

Current Requirements for Defense Contractors and Subcontractors

    Currently, federal contracts (including defense contracts) 
involving the transfer of FCI to a non-Government organization follow 
the requirements specified in FAR clause 52.204-21, Basic Safeguarding 
of Covered Contractor Information Systems.\5\ FAR clause 52.204-21 
requires compliance with 15 security requirements, FAR 52.204-21(b)(1), 
items (i) through (xv). These requirements are elementary for any 
entity wishing to achieve basic cybersecurity.
---------------------------------------------------------------------------

    \5\ <a href="https://www.acquisition.gov/far/52.204-21">https://www.acquisition.gov/far/52.204-21</a>.
---------------------------------------------------------------------------

    Defense contracts involving the transfer of CUI to a non-Government 
organization may include applicable requirements of DFARS clause 
252.204-7012, Safeguarding Covered Defense Information and Cyber 
Incident Reporting.\6\ The DFARS clause 252.204-7012 requires defense 
contractors to provide adequate security on all covered contractor 
information systems by implementing the 110 security requirements 
specified in the National Institute of Standards and Technology (NIST) 
Special Publication (SP) 800-171, Protecting Controlled Unclassified 
Information in Nonfederal Systems and Organizations. The DFARS clause 
252.204-7012 includes additional requirements; for example, defense 
contractors must meet Federal Risk and Authorization Management Program 
(FedRAMP) standards by confirming that their Cloud Service Providers 
(CSP) have achieved the FedRAMP Baseline Moderate or Equivalent 
standard. The DFARS clause 252.204-7012 also requires defense 
contractors to flow down all the requirements to their subcontractors.
---------------------------------------------------------------------------

    \6\ <a href="https://www.acquisition.gov/dfars/252.204-7012-safeguarding-covered-defense-information-and-cyber-incident-reporting">https://www.acquisition.gov/dfars/252.204-7012-safeguarding-covered-defense-information-and-cyber-incident-reporting</a>.
---------------------------------------------------------------------------

    Currently, to comply with DFARS clause 252.204-7012, contractors 
are required to develop a System Security Plan (SSP) \7\ detailing the 
policies and procedures their organization has in place to comply with 
NIST SP 800-171. The SSP serves as a foundational document for the 
required NIST SP 800-171 self-assessment. Self-assessment scores, as 
referenced in DFARS clause 252.204-7020, must be submitted in the DoD's 
Supplier Performance Risk System (SPRS).\8\ The highest score is 110, 
meaning all 110 NIST SP 800-171 security requirements have been fully 
implemented. If a contractor's SPRS score is less than 110, indicating 
security gaps exist, then the contractor must create a Plan of Action 
(POA) \9\ identifying security tasks that still need to be 
accomplished. In essence, an SSP describes the cybersecurity plan the 
contractor has in place to protect CUI. The SSP needs to go through 
each NIST SP 800-171 security requirement and explain how the 
requirement is implemented, monitored, and enforced. This can be 
through policy, technology, or a combination of both. The SSP will also 
outline the roles and responsibilities of security personnel to ensure 
that CUI is appropriately protected.
---------------------------------------------------------------------------

    \7\ Required since November 2016, NIST SP 800-171 security 
requirement 3.12.4 states organizations must ``develop, document, 
and periodically update system security plans that describe system 
boundaries, system environments of operation, how security 
requirements are implemented, and the relationships with or 
connections to other systems.''
    \8\ <a href="https://www.sprs.csd.disa.mil/">https://www.sprs.csd.disa.mil/</a> under OMB control number 
0750-0004.
    \9\ The POA requirement described under DFARS clause 252.204-
7012 is different from a Plan of Action and Milestones (POA&M) 
requirement in CMMC as POAs do not require milestones.
---------------------------------------------------------------------------

    In November 2020, the DoD released its DFARS Interim Rule, the 
Defense Federal Acquisition Regulation Supplement: Assessing Contractor 
Implementation of Cybersecurity Requirements.\10\ The goal of this rule 
was to increase compliance with its cybersecurity regulations and 
improve security throughout the DIB. This rule introduced three new 
clauses--DFARS clause 252.204-7019, DFARS clause 252.204-7020, and 
DFARS clause 252.204-7021.
---------------------------------------------------------------------------

    \10\ <a href="https://www.federalregister.gov/documents/2020/09/29/2020-21123/defense-federal-acquisition-regulation-supplement-assessing-contractor-implementation-of">https://www.federalregister.gov/documents/2020/09/29/2020-21123/defense-federal-acquisition-regulation-supplement-assessing-contractor-implementation-of</a>.
---------------------------------------------------------------------------

    <bullet> DFARS clause 252.204-7019 strengthens DFARS clause 
252.204-7012 by requiring contractors to conduct a NIST SP 800-171 
self-assessment according to NIST SP 800-171 DoD Assessment 
Methodology.\11\ Self-assessment scores must be reported to the 
Department via SPRS. SPRS scores must be submitted by the time of 
contract award and not be more than three years old.
---------------------------------------------------------------------------

    \11\ <a href="https://www.acq.osd.mil/asda/dpc/cp/cyber/docs/safeguarding/NIST-SP-800-171-Assessment-Methodology-Version-1.2.1-6.24.2020.pdf">https://www.acq.osd.mil/asda/dpc/cp/cyber/docs/safeguarding/NIST-SP-800-171-Assessment-Methodology-Version-1.2.1-6.24.2020.pdf</a>
---------------------------------------------------------------------------

    <bullet> DFARS clause 252.204-7020 notifies contractors that DoD 
reserves the right to conduct a higher-level assessment of contractors' 
cybersecurity compliance, and contractors must give DoD assessors full 
access to their facilities, systems, and personnel. Further, DFARS 
clause 252.204-7020 strengthens DFARS clause 252.204-7012's flow down 
requirements by holding contractors responsible for confirming their 
subcontractors have SPRS scores on file prior to awarding them 
contracts.
    <bullet> DFARS clause 252.204-7021 paves the way for rollout of the 
CMMC Program. Once CMMC is implemented, DFARS clause 252.204-7021 
requires contractors to achieve the CMMC level required in the DoD 
contract. DFARS clause 252.204-7021 also stipulates contractors will be 
responsible for flowing down the CMMC requirements to their 
subcontractors.

Additional Requirements for Defense Contractors and Subcontractors 
Discussed in This Proposed Rule

    A key difference between the DFARS 252.204-7012 and CMMC Level 2 
requirements is that compliance with NIST SP 800-171 under DFARS 
252.204-7012 has not been consistently verified. Under CMMC, compliance 
will be checked by independent third-party assessors certified by DoD.
    When this 32 CFR CMMC Program rule is finalized, solicitations for 
defense contracts involving the processing, storing, or transmitting of 
FCI or CUI on a non-Federal system will, in most cases, have a CMMC 
level and assessment type requirement a contractor must meet to be 
eligible for a contract award. CMMC-related contractual processes will 
be addressed in DoD's DFARS Case 2019-D041, Assessing Contractor 
Implementation of Cybersecurity Requirements, which will be proposed by 
the Department in a separate rulemaking.\12\
---------------------------------------------------------------------------

can be found at <a href="https://www.reginfo.gov/public/do/eAgendaMain">https://www.reginfo.gov/public/do/eAgendaMain</a> and 
then selecting the relevant agency and rule name.
---------------------------------------------------------------------------

    This rule establishes the CMMC Program and defines requirements 
both in general and based on the specific CMMC level and assessment 
type required by the contract and applicable subcontract. Each CMMC 
level and assessment type is described.
1. Contracts or Subcontracts With a CMMC Level 1 Self-Assessment 
Requirement
a. Security Requirements
    For CMMC Level 1, contractors and applicable subcontractors are 
already required to implement the 15 security requirements currently 
required by the FAR clause 52.204-21.

[[Page 89060]]

b. Assessment Requirements (New)
    At Level 1, CMMC adds a requirement for contractors and applicable 
subcontractors to verify through self-assessment that all applicable 
security requirements outlined in FAR clause 52.204-21 have been 
implemented. This self-assessment must be performed annually and the 
results must be entered electronically in the Supplier Performance Risk 
System (SPRS) (see Sec.  170.15 for details on CMMC Level 1 Self-
Assessment requirements and procedures, and specifically Sec.  
170.15(a)(1)(i) for the information collection).
c. Affirmation Requirements (New)
    A senior official from the prime contractor and any applicable 
subcontractor will be required to annually affirm continuing compliance 
with the specified security requirements. Affirmations are entered 
electronically in SPRS (see Sec.  170.22 for details on Affirmation 
requirements and procedures).
2. Contracts or Subcontracts With a CMMC Level 2 Self-Assessment 
Requirement
a. Security Requirements
    For CMMC Level 2, contractors and applicable subcontractors are 
already required to implement the 110 security requirements currently 
required by the DFARS clause 252.204-7012, which are aligned with NIST 
SP 800-171 Rev 2.
b. Assessment Requirements (New)
    At Level 2, CMMC adds a requirement for contractors and applicable 
subcontractors to verify that all applicable security requirements 
outlined in NIST SP 800-171 Rev 2 and required via DFARS clause 
252.204-7012 have been implemented. As determined by DoD, program 
contracts will include either a CMMC Level 2 Self-Assessment 
requirement or a CMMC Level 2 Certification Assessment requirement to 
verify a contractor's implementation of the CMMC Level 2 security 
requirements. Selected requirements are allowed to have a Plan of 
Action and Milestones (POA&M) that must be closed out within 180 days 
of the assessment (see Sec.  170.21 for details on POA&M). This self-
assessment must be performed on a triennial basis and the results must 
be entered electronically in SPRS (see Sec.  170.16 for details on CMMC 
Level 2 Self-Assessment requirements and procedures, and specifically 
Sec.  170.16(a)(1)(i) for information collection).
c. Affirmation Requirements (New)
    A senior official from the prime contractor and any applicable 
subcontractor will be required to affirm continuing compliance with the 
specified security requirements after every assessment, including POA&M 
closeout, and annually thereafter. Affirmations are entered 
electronically in SPRS (see Sec.  170.22 for details on Affirmation 
requirements and procedures).
3. Contracts or Subcontracts With a CMMC Level 2 Certification 
Assessment Requirement
a. Security Requirements
    For CMMC Level 2 Certification Assessment, contractors and 
applicable subcontractors are already required to implement the 
security requirements currently required by the DFARS clause 252.204-
7012, which are aligned with NIST SP 800-171 Rev 2.
b. Assessment Requirements (New)
    At Level 2, CMMC adds a requirement for contractors and applicable 
subcontractors to verify that all applicable security requirements 
outlined in NIST SP 800-171 Rev 2 and required via DFARS clause 
252.204-7012 have been implemented. As determined by DoD, program 
contracts will include either a CMMC Level 2 Self-Assessment 
requirement or a CMMC Level 2 Certification Assessment requirement to 
verify a contractor's implementation of the CMMC Level 2 security 
requirements. Selected requirements are allowed to have a POA&M that 
must be closed out within 180 days of the assessment (see Sec.  170.21 
for details on POA&M). The final certification will have up to a three-
year duration. The third-party assessment organization will enter the 
assessment information electronically into the CMMC Enterprise Mission 
Assurance Support Service (eMASS), that will electronically transmit 
the assessment results into SPRS (see Sec.  170.17 for details on CMMC 
Level 2 Certification Assessment requirements and procedures, and 
specifically Sec.  170.17(a)(1)(i) for information collection).
c. Affirmation Requirements (New)
    A senior official from the prime contractor and any applicable 
subcontractor will be required to affirm continuing compliance with the 
specified security requirements after every assessment, including POA&M 
closeout, and annually thereafter. Affirmations are entered 
electronically in SPRS (see Sec.  170.22 for details on Affirmation 
requirements, procedures, and information collection).
4. Contracts or Subcontracts With a CMMC Level 3 Certification 
Assessment Requirement
a. Security Requirements (New)
    For CMMC Level 3, when CMMC becomes a final rule, contractors and 
applicable subcontractors will be required to implement the 24 selected 
security requirements from NIST SP 800-172, as detailed in table 1 to 
Sec.  170.14(c)(4). CMMC Level 2 is a prerequisite for CMMC Level 3.
b. Assessment Requirements (New)
    At Level 3, CMMC adds a requirement for contractors and applicable 
subcontractors to verify through DoD assessment and receive 
certification that all applicable CMMC Level 3 security requirements 
from NIST SP 800-172 have been implemented. Selected requirements are 
allowed to have a POA&M that must be closed out within 180 days of the 
assessment (see Sec.  170.21 for details on POA&Ms). The final 
certification will be valid for up to three years. The DoD assessor 
will enter the assessment information electronically into the eMASS, 
that will electronically transmit the assessment results into SPRS (see 
Sec.  170.18 for details on CMMC Level 3 Certification Assessment 
requirements and procedures, and specifically Sec.  170.18(a)(1)(i) for 
information collection).
c. Affirmation Requirements (New)
    A senior official from the prime contractor and any applicable 
subcontractor will be required to affirm continuing compliance with the 
specified security requirements after every assessment, including POA&M 
closeout, and annually thereafter. Affirmations are entered 
electronically in SPRS (see Sec.  170.22 for details on Affirmation 
requirements, procedures, and information collection).

Summary of Provisions Contained in This Rule

Section 170.1 Purpose

    Section 170.1 addresses the purpose of this rule. It describes the 
CMMC Program and establishes policy for requiring the protection of FCI 
and CUI that is processed, stored, or transmitted on defense contractor 
and subcontractor information systems. The security standards utilized 
in the CMMC Program are from the FAR clause 52.204-21; NIST SP 800-171 
Rev 2; and selected requirements from the NIST SP 800-172, as 
applicable. The purpose of the CMMC Program is for contractors

[[Page 89061]]

and subcontractors to demonstrate that FCI and CUI being processed, 
stored, or transmitted is adequately safeguarded through the 
methodology provided in the rule.

Section 170.2 Incorporation by Reference

    Section 170.2 addresses the standards and guidelines that are 
incorporated by reference. The Director of the Federal Register under 5 
U.S.C. 552(a) and 1 CFR part 51 approves any materials that are 
incorporated by reference (as detailed in the Office of the Federal 
Register's Incorporation By Reference (IBR) Handbook, June 2023). 
Materials that are incorporated by reference in this rule are 
reasonably available. Information on how to access the documents is 
detailed in Sec.  170.2. Materials that are incorporated by reference 
in this rule are from the NIST (see Sec.  170.2(a)), the Committee on 
National Security Systems (see Sec.  170.2(b)), and the International 
Organization for Standardization/International Electrotechnical 
Commission (ISO/IEC) (see Sec.  170.2(c)) which may require payment of 
a fee.

    Note: While the ISO/IEC standards are issued jointly, they are 
available from the ISO Secretariat (see Sec.  170.2(c)).

    The American National Standards Institute (ANSI) IBR Portal 
provides access to standards that have been incorporated by reference 
in the U.S. Code of Federal Regulations at <a href="https://ibr.ansi.org">https://ibr.ansi.org</a>. These 
standards incorporated by the U.S. government in rulemakings are 
offered at no cost in ``read only'' format and are presented for online 
reading. There are no print or download options. All users will be 
required to install the FileOpen plug-in and accept an online end user 
license agreement prior to accessing any standards.
    The materials that are incorporated by reference are summarized 
below.
    (a) Federal Information Processing Standard (FIPS) Publication 
(PUB) 200 (FIPS PUB 200), titled ``Minimum Security Requirements for 
Federal Information and Information Systems'' is the second of two 
security standards mandated by the Federal Information Security 
Management Act (FISMA). It specifies minimum security requirements for 
information and information systems supporting the executive agencies 
of the federal government and a risk-based process for selecting the 
security controls necessary to satisfy the minimum security 
requirements. This standard promotes the development, implementation, 
and operation of more secure information systems within the federal 
government by establishing minimum levels of due diligence for 
information security and facilitating a more consistent, comparable, 
and repeatable approach for selecting and specifying security controls 
for information systems that meet minimum security requirements. This 
document is incorporated by reference as a source for definitions.
    (b) FIPS PUB 201-3, titled ``Personal Identity Verification (PIV) 
of Federal Employees and Contractors'' establishes a standard for a PIV 
system that meets the control and security objectives of Homeland 
Security Presidential Directive-12. It is based on secure and reliable 
forms of identity credentials issued by the Federal Government to its 
employees and contractors. These credentials are used by mechanisms 
that authenticate individuals who require access to federally 
controlled facilities, information systems, and applications. This 
Standard addresses requirements for initial identity proofing, 
infrastructure to support interoperability of identity credentials, and 
accreditation of organizations and processes issuing PIV credentials. 
This document is incorporated by reference as a source for definitions.
    (c) NIST SP 800-37, revision 2, titled ``Risk Management Framework 
for Information Systems and Organizations: A System Life Cycle Approach 
for Security and Privacy'' describes the Risk Management Framework 
(RMF) and provides guidelines for applying the RMF to information 
systems and organizations. The RMF provides a disciplined, structured, 
and flexible process for managing security and privacy risk that 
includes information security categorization; control selection, 
implementation, and assessment; system and common control 
authorizations; and continuous monitoring. The RMF includes activities 
to prepare organizations to execute the framework at appropriate risk 
management levels. The RMF also promotes near real-time risk management 
and ongoing information system and common control authorization through 
the implementation of continuous monitoring processes; provides senior 
leaders and executives with the necessary information to make 
efficient, cost-effective, risk management decisions about the systems 
supporting their missions and business functions; and incorporates 
security and privacy into the system development life cycle. Executing 
the RMF tasks links essential risk management processes at the system 
level to risk management processes at the organization level. In 
addition, it establishes responsibility and accountability for the 
controls implemented within an organization's information systems and 
inherited by those systems. This document is incorporated by reference 
as a source for definitions.
    (d) NIST SP 800-39, titled ``Managing Information Security Risk: 
Organization, Mission, and Information System View'' provides guidance 
for an integrated, organization-wide program for managing information 
security risk to organizational operations (i.e., mission, functions, 
image, and reputation), organizational assets, individuals, other 
organizations, and the Nation resulting from the operation and use of 
federal information systems. SP 800-39 provides a structured, yet 
flexible approach for managing risk that is intentionally broad-based, 
with the specific details of assessing, responding to, and monitoring 
risk on an ongoing basis provided by other supporting NIST security 
standards and guidelines. The guidance provided in this publication is 
not intended to replace or subsume other risk-related activities, 
programs, processes, or approaches that organizations have implemented 
or intend to implement addressing areas of risk management covered by 
other legislation, directives, policies, programmatic initiatives, or 
mission/business requirements. Rather, the risk management guidance 
described herein is complementary to and should be used as part of a 
more comprehensive Enterprise Risk Management (ERM) program. This 
document is incorporated by reference as a source for definitions.
    (e) NIST SP 800-53, revision 5, titled ``Security and Privacy 
Controls for Information Systems and Organizations'' provides a catalog 
of security and privacy controls for information systems and 
organizations to protect organizational operations and assets, 
individuals, other organizations, and the Nation from a diverse set of 
threats and risks, including hostile attacks, human errors, natural 
disasters, structural failures, foreign intelligence entities, and 
privacy risks. The controls are flexible and customizable and 
implemented as part of an organization-wide process to manage risk. The 
controls address diverse requirements derived from mission and business 
needs, laws, executive orders, directives, regulations, policies, 
standards, and guidelines. Finally, the consolidated control catalog 
addresses security and privacy from a functionality perspective (i.e., 
the strength of functions and mechanisms provided by the controls) and 
from an assurance perspective (i.e., the measure

[[Page 89062]]

of confidence in the security or privacy capability provided by the 
controls). Addressing functionality and assurance helps to ensure that 
information technology products and the systems that rely on those 
products are sufficiently trustworthy. This document is incorporated by 
reference as a source for definitions.
    (f) NIST SP 800-82, revision 2, titled ``Guide to Industrial 
Control Systems (ICS) Security'' provides guidance on how to secure 
ICS, including Supervisory Control and Data Acquisition (SCADA) 
systems, Distributed Control Systems (DCS), and other control system 
configurations such as Programmable Logic Controllers (PLC), while 
addressing their unique performance, reliability, and safety 
requirements. The document provides an overview of ICS and typical 
system topologies, identifies typical threats and vulnerabilities to 
these systems, and provides recommended security countermeasures to 
mitigate the associated risks. This document is incorporated by

    (g) NIST SP 800-115, titled ``Technical Guide to Information 
Security Testing and Assessment'' assists organizations in planning and 
conducting technical information security tests and examinations, 
analyzing findings, and developing mitigation strategies. The guide 
provides practical recommendations for designing, implementing, and 
maintaining technical information security test and examination 
processes and procedures. These can be used for several purposes, such 
as finding vulnerabilities in a system or network and verifying 
compliance with a policy or other requirements. The guide is not 
intended to present a comprehensive information security testing and 
examination program but rather an overview of key elements of technical 
security testing and examination, with an emphasis on specific 
technical techniques, the benefits and limitations of each, and 
recommendations for their use. This document is incorporated by 
reference as a source for definitions.
    (h) NIST SP 800-160, Volume 2, revision 1, titled ``Developing 
Cyber-Resilient Systems: A Systems Security Engineering Approach'' 
focuses on cyber resiliency engineering--an emerging specialty systems 
engineering discipline applied in conjunction with systems security 
engineering and resilience engineering to develop survivable, 
trustworthy secure systems. Cyber resiliency engineering intends to 
architect, design, develop, implement, maintain, and sustain the 
trustworthiness of systems with the capability to anticipate, 
withstand, recover from, and adapt to adverse conditions, stresses, 
attacks, or compromises that use or are enabled by cyber resources. 
From a risk management perspective, cyber resiliency is intended to 
help reduce the mission, business, organizational, enterprise, or 
sector risk of depending on cyber resources. This document is 
incorporated by reference as a source for definitions.
    (i) NIST SP 800-171, revision 2, titled ``Security Requirements for 
Controlled Unclassified Information'' provides agencies with 
recommended security requirements for protecting the confidentiality of 
CUI when the information is resident in nonfederal systems and 
organizations; when the nonfederal organization is not collecting or 
maintaining information on behalf of a federal agency or using or 
operating a system on behalf of an agency; and where there are no 
specific safeguarding requirements for protecting the confidentiality 
of CUI prescribed by the authorizing law, regulation, or governmentwide 
policy for the CUI category listed in the CUI Registry. The 
requirements apply to all components of nonfederal systems and 
organizations that process, store, and/or transmit CUI, or that provide 
protection for such components. The security requirements are intended 
for use by federal agencies in contractual vehicles or other agreements 
established between those agencies and nonfederal organizations. This 
document is incorporated by reference as a foundational source for 
definitions and security requirements.
    (j) NIST SP 800-171A, titled ``Assessing Security Requirements for 
Controlled Unclassified Information'' provides federal and nonfederal 
organizations with assessment procedures and a methodology that can be 
employed to conduct assessments of the CUI security requirements in 
NIST SP 800-171. The assessment procedures are flexible and can be 
customized to the needs of the organizations and the assessors 
conducting the assessments. Security assessments can be conducted as 
self-assessments; independent, third-party assessments; or government-
sponsored assessments and can be applied with various degrees of rigor, 
based on customer-defined depth and coverage attributes. The findings 
and evidence produced during the security assessments can facilitate 
risk-based decisions by organizations related to the CUI requirements. 
This document is incorporated by reference as a foundational source for 
definitions and assessment.
    (k) NIST SP 800-172, titled ``Enhanced Security Requirements for 
Controlled Unclassified Information'' provides federal agencies with 
recommended enhanced security requirements for protecting the 
confidentiality of CUI: (1) when the information is resident in 
nonfederal systems and organizations; (2) when the nonfederal 
organization is not collecting or maintaining information on behalf of 
a federal agency or using or operating a system on behalf of an agency; 
and (3) where there are no specific safeguarding requirements for 
protecting the confidentiality of CUI prescribed by the authorizing 
law, regulation, or government-wide policy for the CUI category listed 
in the CUI Registry. The enhanced requirements apply only to components 
of nonfederal systems that process, store, or transmit CUI or that 
provide security protection for such components when the designated CUI 
is associated with a critical program or high value asset. The enhanced 
requirements supplement the basic and derived security requirements in 
NIST SP 800-171 and are intended for use by federal agencies in 
contractual vehicles or other agreements established between those 
agencies and nonfederal organizations. This document is incorporated by 
reference as a foundational source for security requirements.
    (l) NIST SP 800-172A, titled ``Assessing Enhanced Security 
Requirements for Controlled Unclassified Information'' provides federal 
agencies and nonfederal organizations with assessment procedures that 
can be used to carry out assessments of the requirements in NIST SP 
800-172. The assessment procedures are flexible and can be tailored to 
the needs of organizations and assessors. Assessments can be conducted 
as (1) self-assessments; (2) independent, third-party assessments; or 
(3) government-sponsored assessments. The assessments can be conducted 
with varying degrees of rigor based on customer-defined depth and 
coverage attributes. The findings and evidence produced during the 
assessments can be used to facilitate risk-based decisions by 
organizations related to the CUI enhanced security requirements. This

Section 170.3 Applicability

    Section 170.3 identifies entities to which the rule applies and how 
the Department intends to implement the rule. The rule applies to 
defense contractors and subcontractors that will process, store, or 
transmit FCI or CUI, and private-sector businesses or other entities 
that are specified in Subpart C. Government information systems that 
are operated by contractors and subcontractors in support of the 
Government do not apply to this rule. CMMC Program requirements apply 
to DoD solicitations and contracts requiring defense contractors and 
subcontractors to process, store, or transmit FCI or CUI. Exceptions to 
the applicability of this rule are addressed in Sec.  170.3(c)(1) and 
(2). Department Program Managers or requiring activities will determine 
which CMMC Level will apply to a contract or procurement. Applicability 
of the CMMC Level to subcontractors is addressed in Sec.  170.23.
    Section 170.3 addresses the four-phased implementation plan of the 
CMMC Program requirements in solicitations and contracts. Phase 1 
begins on the effective date of the CMMC revision to DFARS 252.204-
7021. More information regarding Phase 1 can be found in Sec.  
170.3(e)(1). Phase 2 begins six months after the start date of Phase 1. 
More information regarding Phase 2 can be found in Sec.  170.3(e)(2). 
Phase 3 begins one calendar year after the start date of Phase 2. More 
information regarding Phase 3 can be found in Sec.  170.3(e)(3). Phase 
4, or full implementation, begins one calendar year after the start 
date of Phase 3. More information regarding Phase 4 can be found in 
Sec.  170.3(e)(4).

Section 170.4 Acronyms and Definitions

    Section 170.4 includes acronyms and definitions used in the rule 
text and can be used as a reference while reading the text and tables. 
CMMC introduces new terms and associated definitions, and customizes 
definitions for existing terms, as applied to the CMMC Program. CMMC-
custom terms and definitions are clearly marked to distinguish from 
terms sourced externally. CMMC also utilizes terms created by other 
authoritative sources, including NIST. Terms from other authoritative 
sources are also listed in Sec.  170.4 and are properly sourced.
    The Department developed the following CMMC-custom terms to enhance 
understanding of the requirements and elements of the CMMC Program and 
welcomes comments on these definitions as part of the proposed rule:

Section 170.5 Policy

    Section 170.5 addresses the policy underlying the rule. The 
protection of FCI and CUI on defense contractor information systems is 
crucial to the continuity of the missions and functions of the DoD. To 
that end, this rule requires that contractors and subcontractors 
implement the specified security requirements for the applicable CMMC 
Level. For CMMC Level 3, safeguards defined in NIST SP 800-172 and DoD-
specified parameters (see table 1 to Sec.  170.14(c)(4)) may be 
required.
    Program Managers and requiring activities identify the applicable 
CMMC Level. Factors used to determine which CMMC Level will be applied 
are included but not limited to the list found in Sec.  170.5(b)(1-5). 
CMMC Program requirements will flow down to subcontractors, as 
applicable (see Sec.  170.23). A DoD Service Acquisition Executive or a 
Component Acquisition Executive may elect to waive inclusion of CMMC 
Program requirements in a solicitation or contract.
    Section 170.5 addresses that the CMMC Program does not alter the 
requirements imposed on contractors and subcontractors in FAR 52.204-
21, DFARS subpart 204.73, or any other applicable safeguarding of 
information requirement. The CMMC Program verifies implementation of 
security requirements in FAR 52.204-21, NIST SP 800-171 Rev 2, and NIST 
SP 800-172, as applicable.

Section 170.6 CMMC PMO

International Laboratory Accreditation Cooperation (ILAC) Mutual 
Recognition Arrangement (MRA) signatory, with a signatory status scope 
of ISO/IEC 17020:2012 and be compliant with ISO/IEC 17011:2017.\13\ 
There is only one Accreditation Body for the DoD CMMC Program at any 
given time, and its primary mission is to authorize and accredit the 
C3PAOs. Prior to the Accreditation Body being compliant with ISO/IEC 
17011:2017 and completing a peer assessment of conformity with the IAAC 
in accordance with the ISO Committee on Conformity Assessment,\14\ the 
Accreditation Body may authorize but not accredit C3PAOs. After the 
Accreditation Body has achieved compliance with ISO/IEC 17011:2017 and 
completed a peer assessment of conformity with the IAAC in accordance 
with the ISO Committee on Conformity Assessment, the Accreditation Body 
may accredit C3PAOs.

reporting, records management, information protection, quality 
assurance, and appeals. The information systems used by C3PAOs to 
process CMMC assessment information have to meet all of the security 
requirements for CMMC Level 2 and will be assessed by DCMA DIBCAC. 
C3PAOs need to comply with ISO/IEC 17020:2012, as well as with the 
Accreditation Body's policies for CoI, CoPC, and Ethics.
    Prior to a C3PAO being compliant with ISO/IEC 17020:2012, the C3PAO 
may be authorized but not accredited. After a C3PAO is compliant with 
ISO/IEC 17020:2012, the C3PAO may be accredited.

Section 170.10 CMMC Assessor and Instructor Certification Organization 
(CAICO)

    Section 170.10 addresses the roles, responsibilities, and 
requirements for the CAICO, the organization that trains, tests, 
authorizes, and certifies CMMC assessors, instructors, and related 
professionals. There is only one CAICO for the DoD CMMC Program at any

[[Page 89065]]

Section 170.14 CMMC Model

    Section 170.14 addresses the structure, security requirement 
contents, organization, sourcing, and numbering of the security 
requirements that comprise the CMMC Model. It also provides an overview 
of the assessment process. The CMMC Model consists of three (3) levels, 
each containing security requirements taken directly from existing 
regulations and guidelines. Firstly, Sec.  170.14(2) defines CMMC Level 
1 as the 15 requirements listed in the FAR clause 52.204-21(b)(1). 
Secondly, Sec.  170.14(3) defines CMMC Level 2 as the 110 requirements 
from the NIST SP 800-171 Rev 2. Lastly, Sec.  170.14(4) defines CMMC 
Level 3 as 24 selected requirements from the NIST SP 800-172.
    The CMMC security requirements are organized into domains following 
the approach taken in NIST SP 800-171 Rev 2. The numbering of the CMMC 
security requirements, addressed in Sec.  170.14(c)(1), is of the form 
DD.L#-REQ where the `DD' is the two-letter domain abbreviation, the 
`L#' is the CMMC Level, and the `REQ' is based directly on the 
numbering in the source. Assessment criteria for these security 
requirements, as described in Sec.  170.14(d), is based on security 
requirement assessment guidance provided in NIST SP 800-171A and NIST 
SP 800-172A.

Section 170.15 CMMC Level 1 Self-Assessment and Affirmation 
Requirements

    Section 170.15 addresses how an OSA will achieve and maintain 
compliance with CMMC Level 1 Self-Assessment. The OSA must successfully 
implement the security requirements listed in Sec.  170.14(c)(2) within 
their Level 1 CMMC Assessment Scope as described in Sec.  170.19(b). 
Successful implementation requires meeting all objectives defined in 
NIST SP 800-171A for the corresponding CMMC Level 1 security 
requirements as outlined in the mapping table 1 to Sec.  
170.15(c)(1)(i).
    After implementation, the OSA must perform a self-assessment to 
verify the implementation and score themselves using the scoring 
methodology provided in Sec.  170.24. All objectives must be met in 
order for a security requirement to be considered fully implemented; no 
security requirements may be placed on a POA&M for Level 1. The OSA 
must then input their results into SPRS as described in Sec.  
170.15(a)(1)(i) and submit an affirmation as described in Sec.  170.22.
    In order to be eligible for a contract with a CMMC Level 1 Self-
Assessment requirement, the OSA must have a Level 1 Self-Assessment and 
have submitted an affirmation. These activities must be completed 
annually.

Section 170.16 CMMC Level 2 Self-Assessment and Affirmation 
Requirements

    Section 170.16 addresses how an OSA will achieve and maintain 
compliance with CMMC Level 2 Self-Assessment. The OSA must successfully 
implement the security requirements listed in Sec.  170.14(c)(3) within 
its Level 2 CMMC Assessment Scope as described in Sec.  170.19(c). 
Successful implementation requires meeting all objectives defined in 
NIST SP 800-171A for the corresponding CMMC Level 2 security 
requirements.
    After implementation, the OSA must perform a self-assessment to 
verify the implementation and score themselves using the scoring 
methodology provided in Sec.  170.24. All objectives must be met in 
order for a security requirement to be considered fully implemented; in 
some cases, if not all objectives are met, some security requirements 
may be placed on a POA&M as provided for in Sec.  170.21. If the 
minimum score has been achieved and some security requirements are in a 
POA&M, the OSA has a Conditional Self-Assessment; if the minimum score 
has been achieved and no security requirements are in a POA&M, the OSA 
has a Final Self-Assessment. For Conditional Self-Assessments, a POA&M 
close-out must be conducted within 180 days as described in Sec.  
170.21(b).
    After both Conditional Self-Assessment and Final Self-Assessment, 
the OSA must input their results into SPRS as described in Sec.  
170.16(a)(1)(i) and submit an affirmation as described in Sec.  170.22.
    In order to be eligible for a contract with a CMMC Level 2 Self-
Assessment requirement, the OSA must have a Level 2 Conditional Self-
Assessment or Level 2 Final Self-Assessment and have submitted an 
affirmation. The Level 2 Self-Assessment must be completed tri-annually 
and the affirmation must be completed annually.

Section 170.17 CMMC Level 2 Certification Assessment and Affirmation 
Requirements

    Section 170.17 addresses how an OSC will achieve and maintain 
compliance with CMMC Level 2 Certification Assessment. The OSC must 
successfully implement the security requirements listed in Sec.  
170.14(c)(3) within its Level 2 CMMC Assessment Scope as described in 
Sec.  170.19(c). Successful implementation requires meeting all 
objectives defined in NIST SP 800-171A for the corresponding CMMC Level 
2 security requirements.
    After implementation, the OSC must hire a C3PAO to perform an 
assessment to verify the implementation. The C3PAO will score the OSC 
using the scoring methodology provided in Sec.  170.24. All objectives 
must be met in order for a security requirement to be considered fully 
implemented; in some cases, if not all objectives are met, some 
security requirements may be placed on a POA&M as defined in Sec.  
170.21. If the minimum score has been achieved and some security 
requirements are in a POA&M, the OSC has a Conditional Certification 
Assessment; if the minimum score has been achieved and no security 
requirements are in a POA&M, the OSC has a Final Certification 
Assessment. For Conditional Certification Assessments, a POA&M close-
out must be conducted within 180 days as described in Sec.  170.21(b).
    After both Conditional Certification Assessment and Final 
Certification Assessment, the C3PAO will input the OSC's results into 
the CMMC instantiation of eMASS as described in Sec.  170.17(a)(1)(i). 
After both Conditional Certification Assessment and Final Certification 
Assessment, the OSC must submit an affirmation as described in Sec.  
170.22.
    In order to be eligible for a contract with a CMMC Level 2 
Certification Assessment requirement, the OSC must have a CMMC Level 2 
Conditional Certification Assessment or CMMC Level 2 Final 
Certification Assessment and have submitted an affirmation. The CMMC 
Level 2 Certification Assessment must be completed tri-annually and the 
affirmation must be completed annually.

Section 170.18 CMMC Level 3 Certification Assessment and Affirmation 
Requirements

    Section 170.18 addresses how an OSC will achieve and maintain 
compliance with CMMC Level 3 Certification Assessment. The OSC must 
have a CMMC Level 2 Final Certification Assessment based on its Level 3 
CMMC Assessment Scope. The OSC must successfully implement the security 
requirements listed in Sec.  170.14(c)(4) and table 1 to Sec.  
170.14(c)(4) within its Level 3 CMMC Assessment Scope as described in 
Sec.  170.19(d). Successful implementation requires meeting all 
objectives defined in NIST SP 800-172A for the corresponding CMMC Level 
3 security requirements.
    After implementation, the OSC must contact DCMA DIBCAC to perform 
an assessment to verify the

[[Page 89066]]

implementation. DCMA DIBCAC will score the OSC using the scoring 
methodology provided in Sec.  170.24. All objectives must be met in 
order for a security requirement to be considered fully implemented; in 
some cases, if not all objectives are met, some security requirements 
may be placed on a POA&M as defined in Sec.  170.21. If the minimum 
score has been achieved and some security requirements are in a POA&M, 
the OSC has a Conditional Certification Assessment; if the minimum 
score has been achieved and no security requirements are in a POA&M, 
the OSC has a Final Certification Assessment. For Conditional 
Certification Assessments, a POA&M close-out must be conducted within 
180 days as described in Sec.  170.21(b).
    After both Conditional Certification Assessment and Final 
Certification Assessment, DCMA DIBCAC will input the OSC's results into 
the CMMC instantiation of eMASS as described in Sec.  170.18(a)(1)(i). 
After both Conditional Certification Assessment and Final Certification 
Assessment, the OSC must submit an affirmation as described in Sec.  
170.22.
    In order to be eligible for a contract with a CMMC Level 3 
Certification Assessment requirement, the OSC must have a CMMC Level 3 
Conditional Certification Assessment or CMMC Level 3 Final 
Certification Assessment and have submitted an affirmation. The CMMC 
Level 3 Certification Assessment must be completed tri-annually and the 
affirmation must be completed annually.

Section 170.19 CMMC Scoping

    Section 170.19 addresses the requirements for the scoping of each 
CMMC Level assessment. Scoping determines which assets are included in 
a given assessment and the degree to which each is assessed. The CMMC 
Assessment Scope is specified prior to any CMMC assessment, based on 
the CMMC Level being assessed. The Level 2 CMMC Assessment Scope may 
also be affected by any intent to achieve a CMMC Level 3 Certification 
Assessment, as detailed in Sec.  170.19(e).
    Scoping for CMMC Level 1, as detailed in Sec.  170.19(b), consists 
of all assets that process, store, or transmit FCI. These assets are 
fully assessed against the applicable CMMC security requirements 
identified in Sec.  170.14(c)(2) and following the procedures in Sec.  
170.15(c). All other assets are out of scope and are not considered in 
the assessment.
    Scoping for CMMC Level 2, as detailed in Sec.  170.19(c), consists 
of all assets that process, store, or transmit CUI, and all assets that 
provide security protections for these assets. These assets are fully 
assessed against the applicable CMMC security requirements identified 
in Sec.  170.14(c)(3) and following the CMMC Level 2 Self-Assessment 
procedures in Sec.  170.16(c) or the CMMC Level 2 Certification 
Assessment procedures in Sec.  170.17(c). In addition, Contractor Risk 
Managed Assets, which are assets that can, but are not intended to, 
process, store, or transmit CUI because of security policy, procedures, 
and practices in place, are documented and are subject to a limited 
check that may result in the identification of a deficiency, as 
addressed in table 1 to Sec.  170.19(c)(1). Finally, Specialized 
Assets, which are assets that can process, store, or transmit CUI but 
are unable to be fully secured, including: Internet of Things (IoT) 
devices, Industrial Internet of Things (IIoT) devices, Operational 
Technology (OT), Government Furnished Equipment (GFE), Restricted 
Information Systems, and Test Equipment, are documented but are not 
assessed against other CMMC security requirements, as addressed in 
table 1 to Sec.  170.19(c)(1). All other assets are out of scope and 
are not considered in the assessment.
    Scoping for CMMC Level 3, as detailed in Sec.  170.19(d), consists 
of all assets that can (whether intended to or not) or do process, 
store, or transmit CUI, and all assets that provide security 
protections for these assets. The CMMC Level 3 Assessment Scope also 
includes all Specialized Assets but allows an intermediary device to 
provide the capability for the Specialized Asset to meet one or more 
CMMC security requirements, as needed. These assets (or the applicable 
intermediary device, in the case of Specialized Assets) are fully 
assessed against the applicable CMMC security requirements identified 
in Sec.  170.14(c)(4) and following the procedures in Sec.  170.18(c). 
All other assets are out of scope and are not considered in the 
assessment.
    If an OSA utilizes an ESP, other than a Cloud Service Provider 
(CSP), the ESP must have a CMMC certification level equal to or greater 
than the certification level the OSA is seeking. For example, if an OSA 
is seeking a CMMC Level 2 Certification Assessment the ESP must have 
either a CMMC Level 2 Certification Assessment or a CMMC Level 3 
Certification Assessment.

Section 170.20 Standards Acceptance

    Section 170.20 addresses how OSCs that, prior to the effective date 
of this rule, have achieved a perfect score on a DCMA DIBCAC High 
Assessment with the same scope as a Level 2 CMMC Assessment Scope, are 
eligible for a CMMC Level 2 Certification Assessment.

Section 170.21 Plan of Action and Milestones Requirements

    Section 170.21 addresses rules for having a POA&M for the purposes 
of a CMMC assessment and satisfying contract eligibility requirements 
for CMMC. All POA&Ms must be closed within 180 days of the initial 
assessment. To satisfy CMMC Level 1 requirements, a POA&M is not 
allowed. To satisfy CMMC Level 2 requirements, both self-assessment and 
certification assessment, a POA&M is allowed. Section 170.21 details 
the overall minimum score that must be achieved and identifies the 
Level 2 security requirements that cannot have a POA&M and must be 
fully met at the time of the assessment. To satisfy CMMC Level 3 
requirements, a POA&M is allowed. Section 170.21 details the overall 
minimum score that must be achieved and identifies the Level 3 security 
requirements that cannot have a POA&M and must be fully met at the time 
of the assessment. Section 170.21 also established rules for closing 
POA&Ms.

Section 170.22 Affirmation

    Section 170.22 addresses that the OSA's affirming official must 
affirm, in SPRS, compliance with the appropriate CMMC Self-Assessment 
or Certification Assessment: upon completion of any conditional or 
final assessment, annually following final assessment, and following a 
POA&M closeout assessment (as applicable).

Section 170.23 Application to Subcontractors

    Section 170.23 addresses flow down of CMMC requirements from the 
prime contractor to the subcontractors in the supply chain. Prime 
contractors shall comply and shall require subcontractor compliance 
throughout the supply chain at all tiers with the applicable CMMC level 
for each subcontract as addressed in Sec.  170.23(a).

Section 170.24 CMMC Scoring Methodology

    Section 170.24 addresses the assessment finding types MET, NOT MET, 
and NOT APPLICABLE (N/A) in the context of CMMC assessments, and the 
CMMC Scoring Methodology used to measure the implementation status of 
security requirements for CMMC Level 2 and CMMC Level 3. Scoring is not 
calculated for CMMC Level 1 since all

[[Page 89067]]

requirements must be MET at the time of assessment.
    For CMMC Level 2, the maximum score is the total number of 
requirements and is the starting value for assessment scoring. Any 
requirement that has one or more NOT MET objectives reduces the current 
score by the value of the specific requirement. Values for each CMMC 
Level 2 requirement are enumerated in Sec.  170.24(c)(2)(i)(B).
    For CMMC Level 3, the maximum score is the total number of 
requirements and is the starting value for assessment scoring. Any 
requirement that has one or more NOT MET objectives reduces the current 
score by the value of the specific requirement. CMMC Level 3 does not 
use varying values; the value for each requirement is one (1), as 
described in Sec.  170.24(c)(3).

Appendix A to Part 170: Guidance

    Appendix A lists the guidance documents that are available to 
support defense contractors and the CMMC Ecosystem in the 
implementation and assessment of CMMC requirements.

Discussion of Public Comments and Resulting Changes

    As part of standing up version 1 of the CMMC Program, the 
Department of Defense published a DFARS interim final rule, ``Assessing 
Contractor Implementation of Cybersecurity Requirements'' in the 
Federal Register on September 29, 2020 (85 FR 61505). The Department 
received approximately 750 comments on the DFARS interim final rule 
pertaining to elements of the CMMC Program that are now being addressed 
in this rule. Those comments are summarized and addressed in the 
discussion and analysis.
    In addition to comments on elements of the CMMC Program, DoD also 
received comments on the associated DFARS text, solicitation 
provisions, and contract clauses relating to the CMMC Program. The CMMC 
Program requirements proposed in this rule will be implemented in the 
DFARS, as needed, which may result in changes to current DoD 
solicitation provisions and contract clauses relating to DoD's 
cybersecurity protection requirements, including DFARS clause 252.204-
7021, CMMC Requirements. DoD will address comments regarding the DFARS 
clause 252.204-7021 in a separate 48 CFR rulemaking.

1. Service Providers

    Comment: Multiple commenters asked about applicability of the CMMC 
Program to a variety of service providers. One commenter requested 
clarification regarding how CUI controls apply to internet Service 
Providers and their globally sourced service support because of the 
prohibition of foreign dissemination for CUI. Two commenters suggested 
that common carrier telecommunications (often termed as Plain-Old-
Telephone-Services (POTS)) and similar commercial services (cloud 
services, external service providers) should be treated as commercial 
off-the-shelf (COTS), and so excluded from CMMC certification 
requirements. One commenter expressed concerns about the impact of the 
rule on the telecom industry. One commenter recommended that, to limit 
the burden of CMMC implementation, contractors providing commercial 
services to support COTS items, such as technical support for software, 
should receive the same exceptions as other COTS contracts.
    Response: The CMMC Program will result in cybersecurity protection 
and assessment requirements for defense contractors and subcontractors. 
CMMC Level requirements will apply only if a defense contractor or 
subcontractor handles FCI or CUI on its own contractor information 
systems. If so, then under CMMC, the contractor or subcontractor will 
be required to comply with the cybersecurity protection and assessment 
requirements associated with the appropriate Level. As such, CMMC Level 
requirements will not apply to internet Service Providers or other 
telecommunications service providers (i.e., common carriers), unless 
those entities themselves are or intend to become defense contractors 
or subcontractors. In addition, there is no general prohibition of 
foreign dissemination for CUI, although certain CUI may be subject to 
export restrictions. Commercial item determinations per 48 CFR 15, to 
include those relating to common carrier telecommunications or cloud 
services, are not defined by CMMC. With respect to the CMMC Assessment 
Scope, although they provide connectivity for contractor systems, and 
the common carrier link is within the boundary of the contractor's 
system, the common carrier's information system is not within the 
contractor's CMMC Assessment Scope as long as CUI is encrypted during 
transport across the common carrier's information system.

2. Joint Ventures

    Comment: Multiple commenters asked for clarification on how to 
handle joint ventures with respect to DFARS clause 252.204-7021.
    Response: The CMMC Program requirements proposed in this rule will 
be implemented in the DFARS, as needed, which may result in changes to 
current DoD solicitation provisions and contract clauses, including 
DFARS clause 252.204-7021. As such, DoD cannot address applicability of 
current DFARS clause 252.204-7021 at this time. With respect to joint 
ventures, CMMC Program requirements will apply to information systems 
associated with the contract efforts that process, store, or transmit 
FCI or CUI, and to any information system that provides security 
protections for such systems, or information systems not logically or 
physically isolated from all such systems.

3. Internet of Things/Operational Technology

    Comment: Multiple commenters noted the applicability of the CMMC 
requirements to Internet of Things (IoT) and Operational Technology 
(OT) systems was unclear. Several commenters expressed concerns about 
the impact of the rule on factories and OT.
    Response: CMMC security requirements apply to information systems 
associated with the contract efforts that process, store, or transmit 
FCI or CUI, and to any information system that provides security 
protections for such systems; or are not logically or physically 
isolated from all such systems. In accordance with Sec.  170.19, an 
OSA's IoT or OT systems located within its Level 1 or Level 2 CMMC 
Assessment Scope are not assessed; however, for CMMC Level 2 they are 
required to be documented in the System Security Plan (SSP). When a 
CMMC Level 2 Certification Assessment is performed as a precursor to a 
CMMC Level 3 Certification Assessment, the IOT and OT (and all other 
Specialized Assets) should be assessed against all CMMC Level 2 
security requirements as described in Sec.  170.18(a)(1). For CMMC 
Level 3, an OSC's IoT or OT located within its CMMC Assessment Scope 
are assessed against all CMMC security requirements unless they are 
physically or logically isolated. However, for IoT and OT (and all 
other Specialized Assets), it is permissible to use intermediary 
devices to provide the capability for the specialized asset to meet 
CMMC Level 3 security requirements.

4. Government Furnished Equipment

    Comment: One commenter questioned how the interim rule applies to 
Government Furnished Equipment (GFE) in a `test' versus a `production 
environment.'
    Response: As described in Sec.  170.3, CMMC security requirements 
will apply

[[Page 89068]]

to any information system associated with the contract efforts that 
process, store, or transmit FCI or CUI, and to any information system 
that provides security protections for such systems; or information 
systems not logically or physically isolated from all such systems. 
This includes when a `Test Environment' processes, stores, or transmits 
FCI or CUI; provides security protections for such systems; or is not 
logically or physically isolated from such systems. See Sec.  170.19 
and the response to public comment under the heading 3. Internet of 
Things/Operational Technology in the Discussion of Comments and Changes 
section of this preamble for additional details on defining the scope 
of CMMC assessments.
    If GFE cannot be configured to meet all the NIST SP 800-171 Rev 2 
requirements or must be maintained in a specified configuration which 
does not comply with NIST SP 800-171 Rev 2, additional protections such 
as physical or logical isolation may be used for risk mitigation in 
accordance with the treatment of Specialized Assets as defined in table 
1 to Sec.  170.19(c)(1) CMMC Level 2 Scoping.

5. Fundamental Research

    Comment: Multiple commenters requested that DoD clarify the 
application of CMMC requirements to fundamental research. Commenters 
described adverse consequences of not explicitly exempting fundamental 
research from the CMMC requirements, noting that institutions of higher 
education will have to pull out of research agreements with the 
Department, may no longer accept DoD funds because the resource burden 
would be cost prohibitive to both the institution and its partners, and 
the burdens imposed by even CMMC Level 1 requirements would hinder the 
progress of fundamental research. These commenters also noted that 
restrictions on posting of public information would inhibit open 
collaboration and the exchange of ideas that is critical to the 
advancement of scientific discovery. Commenters also requested that the 
Department clarify that subcontracts scoped as fundamental research 
also be exempt from CMMC requirements.
    Response: CMMC Program requirements are designed to provide 
increased assurance to the Department that defense contractors can 
adequately protect FCI and CUI, in accordance with already applicable 
regulations and standards. Fundamental research is defined by National 
Security Defense Directive (NSDD)-189 \17\ as `basic and applied 
research in science and engineering, the results of which ordinarily 
are published and shared broadly within the scientific community, as 
distinguished from proprietary research and from industrial 
development, design, production, and product utilization, the results 
of which ordinarily are restricted for proprietary or national security 
reasons.' CMMC Program requirements apply only to defense contractors 
and subcontractors who handle FCI and CUI on an information system 
associated with a contract effort or any information system that 
provides security protections for such systems, or information systems 
not logically or physically isolated from all such systems. Fundamental 
research that is `shared broadly within the scientific community' is 
not, by definition, FCI or CUI; however, other research-related 
information that is provided to or handled by contractors as part of 
contract performance may be FCI or CUI, thus may trigger application of 
CMMC Level requirements. If DoD determines the information handled by 
contractors pursuant to the fundamental research contract activities is 
or will become FCI or CUI, the information would be required to be 
processed, stored, or transmitted on an information system compliant 
with the appropriate CMMC Level.

---------------------------------------------------------------------------

6. International--Foreign DIB Partners/Non-U.S. Contractors

    Comment: Multiple commenters asked if international subcontractors 
of a U.S. prime will require CMMC certification. Commenters also asked 
if there is a strategy for legally implementing CMMC requirements 
beyond the U.S. DIB, and if an enterprise-level resolution has been 
developed to address foreign DIB sovereignty. One commenter suggested 
that some foreign governments have issued guidance to their local 
companies directing them not to accept CMMC flow down requirements.
    One commenter expressed concern regarding the impact of CMMC to 
existing bilateral/multilateral security agreements. Another commenter 
asked if the foreign DIB will be authorized to evaluate U.S. DIB and 
vice versa. One non-U.S. commenter suggested using the existing 
Facility Security Clearance process to ensure a company is compliant 
with CMMC in accordance with national legislation.
    Response: Contractors are required to comply with all terms and 
conditions of the contract, to include terms and conditions relating to 
cybersecurity protections and assessments. In addition, offerors will 
be required to comply with the pre-award CMMC requirement. This holds 
true when a contract clause is flowed down to subcontractors. The 
Facility Security Clearance process does not apply to unclassified 
information systems owned by, or operated on behalf of, a non-federal 
entity (e.g., contractors), and, therefore, does not apply to systems/
networks that will be subject to CMMC requirements. This rule makes no 
distinction about which C3PAOs may assess which companies seeking 
certification. For more details on C3PAO requirements, see Sec.  170.9.

7. CUI and FCI

a. Marking and Identifying CUI
    Comment: Multiple commenters asked for clarification regarding 
definition, marking, and identification of CUI as related to CMMC 
requirements and DFARS clause 252.204-7021. One commenter asked if the 
definition of DoD CUI applies to the CUI required to be safeguarded 
under the CMMC clause. Another asked if DFARS clause 252.204-7021 
includes information that requires protection under DFARS clause 
252.204-7012.
    One commenter requested that the Department confirm that, under 
CMMC, contractors will only be responsible for protecting CUI that is 
clearly marked upon receipt from the Department and created by 
contractors.
    Response: If the contract includes a CMMC Level requirement, 
contractors will be required to protect FCI and CUI, as applicable, 
through fulfillment of the designated CMMC Level security requirements. 
CMMC does not in any way change the DoD requirements regarding the 
definition, marking, and protection of CUI.
    If DFARS clause 252.204-7012 applies, contractors are required to 
safeguard covered defense information in accordance with the terms and 
conditions of the clause and contract, which includes information 
developed in support of the contract. CMMC does not change these 
requirements.
b. Relationship of FCI and CUI to the CMMC Requirements
    Comment: One commenter suggested that the inclusion of FCI in CMMC 
needs significant clarification. Others asked if FCI references within 
the CMMC Model [1.0] and nonpublic DoD information references in 
Department of

[[Page 89069]]

Defense Instruction (DoDI) 8582.01 \18\ are the same type of 
information, and if DoDI 8582.01 is the definitive DoD policy for FCI 
and DoD standards regarding the requirements under FAR clause 52.204-
21.
---------------------------------------------------------------------------

    \18\ <a href="https://www.esd.whs.mil/Portals/54/Documents/DD/issuances/DoDi/858201p.pdf?ver=2019-12-09-143118-860">https://www.esd.whs.mil/Portals/54/Documents/DD/issuances/DoDi/858201p.pdf?ver=2019-12-09-143118-860</a>.
---------------------------------------------------------------------------

    Response: The CMMC Program requirements for Level 1 will apply when 
the contract effort requires contractors to process, store, or transmit 
FCI on its unclassified information system. If CUI is processed, 
stored, or transmitted on a contractor information system, a higher 
level of CMMC compliance or certification is required. The CMMC Level 
required to protect CUI (i.e., CMMC Level 2 Self-Assessment as 
described in Sec.  170.16, CMMC Level 2 Certification Assessment as 
described in Sec.  170.17, or CMMC Level 3 Certification Assessment as 
described in Sec.  170.18) is determined by the Department based upon 
the sensitivity of the CUI and will be identified in the solicitation.
    The CMMC Program uses the definitions of FCI from FAR 4.1901 and 
CUI from 32 CFR 2002, which are the definitive sources for these 
definitions. DoDI 8582.01, published on December 9, 2019, points to FAR 
clause 52.204-21 and DFARS clause 252.204-7012, both of which preceded 
it, to address the safeguarding requirements for FCI and CUI. CMMC 
builds from those requirements by requiring that defense contractors 
and subcontractors provide assurance, either with Self-Assessments, 
Third-Party Assessments, or Level 3 Assessments, as required, that they 
have implemented the required information protection requirements.

8. Small Business/Entities

a. Assistance/Support for Small Business
    Comment: Several commenters suggested that in order to successfully 
implement cybersecurity requirements, contractors require support from 
the Department. One commenter suggested DoD should perform an analysis 
of each requirement and ensure that necessary support structures are in 
place and fully functioning prior to implementing this rule, and that 
access to tech support/solutions should be provided. Multiple 
commenters suggested that more support and guidance is needed for small 
businesses trying to comply with CMMC. One commenter suggested that DoD 
should relax affiliation rules (in conjunction with the Small Business 
Association (SBA)) to allow small companies to work together to meet 
CMMC requirements while spreading the cost over a larger base and 
expand mentor-prot[eacute]g[eacute] agreements for larger businesses to 
help smaller companies with CMMC appraisals.
    One commenter expressed concern for non-traditional, innovative 
companies that are coming in through the Small Business Innovation 
Research (SBIR) and Small Business Technology Transfer (STTR) process 
and asked what DoD is doing to help them become compliant. Another 
noted that if CMMC Level 1 will be the minimum requirement for SBIRs 
and STTRs, regardless of whether they include FCI, it may significantly 
limit the number of universities that can partner with small businesses 
under these awards.
    Response: DoD's Office of Small Business and Technology 
Partnerships (OSBTP) is working to provide SBIR/STTR programs with 
support for CMMC implementation through the use of Technical and 
Business Assistance. The SBA's affiliation rules are codified at 13 CFR 
121.103, available at <a href="https://www.ecfr.gov/current/title-13/chapter-I/part-121">https://www.ecfr.gov/current/title-13/chapter-I/part-121</a>. Any change to the SBA's affiliation rules is outside the 
scope of this rulemaking.
    The CMMC Program is designed to increase assurance that defense 
contractors do in fact, comply with information protection requirements 
to adequately protect FCI and CUI. Additional information to assist 
contractors regarding DoD's current information security protection 
requirements may be found in Frequently Asked Questions (FAQs) 
Regarding the Implementation of DFARS subpart 204.73, published at 
<a href="https://DoDprocurementtoolbox.com/">https://DoDprocurementtoolbox.com/</a>.
b. Impact of Cost
    Comment: Multiple commenters commented on the cost impact of CMMC 
to small businesses, suggesting that the cost to become and remain 
compliant is too high. Several commenters added that small businesses 
limited by finances won't be able to compete, which could be 
detrimental to the supply chain and efforts to meet national defense 
goals, and that the rule fails to provide any consideration for the 
future loss of technology acquisition should small businesses be 
inadvertently precluded from participation. Other commenters suggested 
that the impact of CMMC will be a profound and significant obstacle to 
businesses due to their lack of resources as compared to their large 
business competitors, adding that the requirement to have the same 
measures in place for any company, regardless of size, incurs a higher 
percentage of indirect cost for small businesses. Multiple commenters 
remarked on the limited or lack of options for a small business to 
recover costs.
    Response: The estimated costs attributed to this rule do not 
include the costs associated with compliance with existing 
cybersecurity requirements under FAR clause 52.204-21 or associated 
with implementing NIST SP 800-171 requirements in accordance with DFARS 
clause 252.204-7012, Safeguarding Covered Defense Information and Cyber 
Incident Reporting. To the extent that defense contractors or 
subcontractors have already been awarded DoD contracts or subcontracts 
that include these clauses, and process, store, or transmit FCI or CUI 
in support of the performance of those contracts, costs for 
implementing those cybersecurity requirements should have already been 
incurred and are not attributed to this rule. Those costs are distinct 
from costs associated with undergoing a CMMC assessment to verify 
implementation of those security requirements. The CMMC Program does 
not levy additional information security protection requirements for 
CMMC Levels 1 and 2. The value of DoD's sensitive information (and 
impact of its loss to the Department) does not diminish when it moves 
to contractors--prime or sub, large or small.
    A Regulatory Flexibility Analysis was conducted. In comparison to 
CMMC 1.0, DoD has now eliminated the requirement for organizations to 
hire a third-party assessment organization to comply with CMMC Level 1. 
The CMMC Program requirements further address cost concerns by 
permitting self-assessment at Level 1 and at Level 2 for some contracts 
that are not designated to require the added assurance of C3PAO 
assessment.
    In addition, resources available through the DoD Office of Small 
Business Programs (OSBP) may help defray cybersecurity costs by helping 
companies stay up to date with the latest cybersecurity policies and 
best practices. The OSBP also partners with the NIST and its 
Manufacturing Extension Partnership (MEP) programs (<a href="https://www.nist.gov/mep">https://www.nist.gov/mep</a>), which operate across the U.S. to provide resource 
and funding assistance options.
    The Department currently has no plans for separate reimbursement of 
costs to acquire cybersecurity capabilities or a required cybersecurity 
certification that may be incurred by an offeror on a DoD contract. 
Costs may be recouped via competitively set prices, as companies see 
fit.

[[Page 89070]]

c. Alternative Implementation
    Comment: Multiple commenters requested that the government give 
small businesses time for CMMC compliance post-contract award. One 
commenter recommended that DoD consider only requiring government 
assessment of NIST SP 800-171 compliance (vice private third party) for 
small businesses, even at lower CMMC assessment levels, thus offsetting 
a higher burden level to small businesses. Several commenters commented 
on the need to include exemptions for small businesses that do not 
possess CUI and have never been contracted by the government. One added 
that DoD should identify portions of contracts which won't require CMMC 
so that small businesses are afforded maximum practicable opportunity 
regardless of their CMMC status.
    Response: The DoD has determined that the assessment of the ability 
of a prospective contactor to adequately protect FCI and CUI that will 
be processed, stored, or transmitted on information systems during 
contract performance is a requirement prior to award of any prime 
contract or subcontract. Failure to assess a prospective contractor's 
ability to comply with applicable information security protection 
requirements, such as NIST SP 800-171 Rev 2, risks significant 
performance delays if information cannot be shared immediately at 
contract award due to lack of compliance. As applicable, the awardee 
must be capable of processing, storing, and transmitting FCI and CUI at 
the start of the performance period, regardless of the business size of 
the awardee. The CMMC Program has simplified requirements for Level 1 
and 2 assessments in some contracts. Specifically, although contractors 
must still implement and maintain the security requirements set forth 
in FAR 52.204-21 to protect FCI and set forth in the NIST SP 800-171 
Rev 2 to protect CUI, the requirement to hire a third-party assessment 
organization for CMMC Level 1 was eliminated, and for some contracts, 
contractors may be permitted to self-assess compliance with CMMC Level 
2. Annual affirmations are also required for CMMC Level 1 and 2.
    Prospective contractors must make a business decision regarding the 
type of DoD business they wish to pursue and understand the 
implications for doing so. If an offeror or current DoD contractor or 
subcontractor has self-assessed then later decides to pursue a contract 
or subcontract requiring a certification at CMMC Level 2 or 3, it will 
need to factor in the time and investment necessary to hire a third-
party assessment organization and achieve certification as a condition 
of contract award.
    Public comments received illustrate that some small businesses may 
be unaware of how to propose cybersecurity-related costs for cost-type 
contracts. This rule does not change existing contract cost principles 
or procedures. For firm-fixed priced efforts, market supply and demand 
dictates profitability and bid prices, and underlying costs are not 
itemized.

9. Disputes Regarding CMMC Assessments

    Comment: Multiple commenters asked about the CMMC assessment 
dispute resolution process, with regard to which standards would be 
followed, how much time would be available to appeal findings, the 
types of complaints that could be raised, any limits to the costs or 
schedule required for dispute resolution, and roles and 
responsibilities of the DoD, C3PAOs, and the Accreditation Body. 
Commenters also wanted to know whether a tiered recourse process would 
be available to resolve contractor objections to the initial 
resolution. Two commenters expressed concerns regarding potential 
impacts of C3PAO assessment errors. Two commenters requested 
clarification regarding whether the CMMC Level required by the DoD or a 
prime contractor could be contested.
    Response: The CMMC assessment appeal process (formerly referred to 
as dispute resolution) described in the DFARS Case 2019-D041 
Supplementary Information has changed and is described in Sec.  
170.9(b)(20) and Sec.  170.8(b)(16). The appeals process is derived 
from and consistent with ISO/IEC 17020:2012 and ISO/IEC 17011:2017. 
Each C3PAO is required to have a time-bound, internal appeals process 
to address disputes related to perceived assessor errors, malfeasance, 
and unethical conduct. Requests for appeals will be reviewed and 
approved by individual(s) within the C3PAO not involved in the original 
assessment activities in question. OSCs can request a copy of the 
process from their C3PAO. If a dispute regarding assessment findings 
cannot be resolved by the C3PAO, it will be escalated to the 
Accreditation Body. The decision by the Accreditation Body will be 
final.
    A request for an appeal about an assessor's professional conduct 
that is not resolved with the C3PAO will be escalated and resolved by 
the Accreditation Body.
    The issue of C3PAO liability is between an OSC and the C3PAO with 
which it contracts to do the assessment.
    Any questions about the CMMC Level required by the solicitation 
should be directed to the contracting officer for the affected 
contractor.

10. Acceptance of Alternate Standards

a. NIST SP 800-171 Rev 2 DoD Assessments and CMMC Assessments
    Comment: Multiple commenters asked for clarification on reciprocity 
between NIST SP 800-171 Rev 2 DoD Assessments and CMMC assessments.
    Response: As stated in Sec.  170.20(a), DoD intends to allow 
qualified standards acceptance of High confidence assessment using NIST 
SP 800-171 Rev 2 for CMMC Level 2. However, the CMMC Program 
requirements proposed in this rule will be implemented in the DFARS, as 
needed, which may result in changes to current DoD solicitation 
provisions and contract clauses relating to cybersecurity assessments.
b. Cloud Standards
    Comment: Many commenters expressed concerns regarding CMMC 
recognition of Federal Risk and Authorization Management Program 
(FedRAMP) and requested guidance on which FedRAMP baselines, if any, 
would be granted standards acceptance at each CMMC Level. A few 
commenters sought assurance that DoD Cloud Computing Security 
Requirements Guide (SRG) Impact Levels 4 and 5 would not be applied to 
CMMC Level 3.
    Response: CMMC does not offer comprehensive acceptance of FedRAMP. 
The CMMC Program allows the acceptance of FedRAMP environments in some 
cases to meet CMMC requirements in connection with use of a Cloud 
Service Provider (CSP). If an OSC uses an external CSP to process, 
store, or transmit CUI or to provide security protection for any such 
component, the OSC must ensure the CSP's product or service offering 
either (1) is authorized as FedRAMP Moderate or High on the FedRAMP 
Marketplace; or (2) meets the security requirements equivalent to those 
established by the Department for the FedRAMP Moderate or High 
baseline. The CSP will provide evidence that its product or service 
offering meets the security requirements equivalent to FedRAMP Moderate 
or High by providing a body of evidence (BOE) that attests to and 
describes how the CSP's product or service offering meets the FedRAMP 
baseline security requirements. Note that for any portion of the on-
premises (internal) network

[[Page 89071]]

that interacts with the cloud service offering and is within the CMMC 
Assessment Scope, the OSC is required to meet all applicable CMMC 
requirements to achieve certification.
    The DoD Cloud Computing SRG applies to DoD-provided cloud services 
and those provided by a contractor on behalf of the department, i.e., a 
commercial cloud service provider or integrator. Cloud Computing SRG 
does not apply to CMMC.
c. Other Standards
    Comment: Numerous commenters asked whether CMMC could leverage the 
results of other assessments, such as ISO/IEC 27001/27002, NIST SP 800-
53, NIST SP 800-172, HITRUST, DoE Cybersecurity Capability Maturity 
Model, NIAP Common Criteria Testing Laboratory Services (CCEVS), 
Committee on National Security Systems (CNSS) Instruction No. 12533 
(CNSSI 12533), ISA/IEC-62443, DoD's Security Technical Implementation 
Guides (STIG), NIST Cyber Security Framework (CSF), NIST Risk 
Management Framework (RMF), the American Institute of CPAs Service and 
Organizational Controls, Service and Organization Controls (SOC) Trust 
Services Criteria (SOC 2), ISA/IEC-62443, ITAR, Criminal Justice 
Information Services (CJIS) security standards, and non-ISO/IEC 
standards used by foreign partners such as the Australian Cybersecurity 
Centre Essential Eight Maturity Model.
    Response: The CMMC Program standards acceptance is defined in Sec.  
170.20 of this rule.

11. CMMC Assessment Scope

    Comment: Multiple commenters requested details on assessment 
boundaries and what systems are in-scope for a CMMC assessment. 
Questions included how assessment boundaries are defined, how networks 
composed of federal components (including systems operated on behalf of 
the government) and non-federal components are addressed, how 
centralized security services are treated, and how ``enduring 
exceptions'' are handled.
    Response: Sec.  170.19 states that prior to a CMMC assessment, the 
OSA must define the CMMC Assessment Scope for the assessment, 
representing the boundary with which the CMMC assessment will be 
associated. This section includes detailed guidance on how to define 
the CMMC Assessment Scope, how different categories of equipment are 
defined to be in- or out-of-scope for an assessment, how the security 
of specialized equipment is expected to be managed, External Service 
Providers considerations, and the incorporation of people, technology, 
and facilities into the boundary.
    GFE, IoT, OT, and, as defined, Restricted Information Systems and 
Test Equipment are categorized as ``Specialized Assets'' in Sec.  
170.19. NIST SP 800-171 Rev 2 uses the term ``enduring exceptions'' to 
describe how to handle exceptions for Specialized Assets.

12. Applicability of Multiple CMMC Levels

    Comment: Two commenters sought confirmation that it is acceptable 
for contractors with multiple business segments to have one or more 
CMMC assessments (e.g., one segment at Level 1, another at Level 2). 
Commenters also wanted to know if systems within the scope of an 
assessment require multiple assessments if the systems are used to 
support tasks under multiple contracts. Another asked, if a company has 
multiple Commercial and Government Entity (CAGE) codes, whether a 
single assessment can cover all CAGE codes.
    Response: Yes, it is possible to have different business segments 
or different enclaves assessed or certified at different CMMC Levels. A 
CMMC assessment can be restricted to a particular segment or enclave 
based on the defined CMMC Assessment Scope, and an OSA can define 
multiple CMMC Assessment Scopes. Thus, a business segment that only 
supports Level 1 (FCI) efforts can identify a boundary that is assessed 
against Level 1 requirements, and another segment that supports Level 2 
(CUI) efforts can identify a different boundary that is assessed 
against Level 2. Offerors will be required to attain CMMC 
certification, when applicable, at or above the level required by the 
solicitation, by the time of award (or option period exercise) and must 
maintain their CMMC status throughout the life of the contract, task 
order, or delivery order.

13. CMMC Implementation Timeline and Pilot Program

a. CMMC Schedule
    Comment: There were many comments requesting clarification or 
justification regarding the general roll-out schedule for DFARS clause 
252.204-7021. Some commenters requested program acceleration and others 
advocated for delays. Two commenters were confused by statements in the 
Federal Register Notice that the timeline for implementation across the 
DoD contractor population would be seven years, but that all contracts 
would include the CMMC clause in five years, at the end of the roll-
out.
    Response: The DoD is implementing a phased implementation for the 
CMMC Program and intends to introduce CMMC requirements in 
solicitations over a three-year period to provide appropriate ramp-up 
time. The Department anticipates it will take two years for companies 
with existing contracts to become CMMC certified.
    In response to public comment, assessment requirements in CMMC have 
been simplified to three tiers, and DoD is developing policy to guide 
Program Managers through a time-phased introduction of CMMC 
requirements. From the effective date of the DFARS rule that will 
implement CMMC requirements, DoD will include CMMC self-assessment 
requirements in solicitations when warranted by the FCI and CUI 
categories associated with the planned effort. A similar requirement 
for CUI has been in place since publication of the September 2020 rule 
that implemented DFARS provision 252.204-7019, which requires offerors 
to submit NIST SP 800-171 Rev 2 self-assessment results in the SPRS as 
a condition of award. DoD intends to include CMMC requirements for 
Levels 1, 2, and 3 in all solicitations issued on or after October 1, 
2026, when warranted by any FCI or CUI information protection 
requirements for the contract effort. In the intervening period, DoD 
Program Managers will have discretion to include CMMC requirements in 
accordance with DoD policies.
b. CMMC Pilot Program
    Comment: Multiple commenters wanted more information about the 
roll-out of the CMMC pilot program, including transparency about which 
acquisition programs are being considered for inclusion prior to the 
release of a solicitation. Commenters requested details on the 
``provisional period,'' whether there would be a break between the 
pilot program and the official launch of the CMMC Program, whether 
there would be an assessment on the effectiveness of the pilot, and if 
lessons learned from the pilot would be shared across the community.
    Response: CMMC 1.0 did include a CMMC Pilot program; however, CMMC 
2.0 does not include pilots. Instead, upon the effective date of the 
associated CMMC DFARS rule, the Department intends to begin including 
CMMC self-assessment requirements when applicable, for protection of 
FCI and CUI.

[[Page 89072]]

c. Communicating CMMC Requirements
    Comment: Two commenters requested that, during the phased rollout 
of CMMC, defense contractors be forewarned of DoD plans to include a 
CMMC requirement in an upcoming solicitation. They asked for 
transparency with respect to which contracts were being considered for 
CMMC requirements.
    Response: Offerors and contractors will be informed of CMMC 
requirements in solicitations through (1) the specification of a 
required CMMC Level, and (2) inclusion of the appropriate DFARS 
provisions or clauses. There is no plan to advertise a list of 
solicitations that will or may include CMMC requirements. The 
implementation plan described in Sec.  170.3(e) addresses phase-in of 
CMMC requirements.
d. Market Capacity for Assessments
    Comment: Multiple commenters wanted details about assessor 
availability and were concerned that a lack of assessors would impact 
the schedule for including CMMC requirements in solicitations and 
contractor planning to attain CMMC certification to meet those 
requirements.
    Response: The phased implementation plan described in Sec.  
170.3(e) is intended to address ramp-up issues, provide time to train 
the necessary number of assessors, and allow companies the time needed 
to understand and implement CMMC requirements. An extension of the 
implementation period or other solutions may be considered in the 
future to mitigate any C3PAO capacity issues, but the Department has no 
such plans at this time. If changes to the implementation plan occur, 
DoD policies that govern requirements definition in the acquisition 
process will be modified.
e. Certification Sustainment During Validity Period
    Comment: Three commenters asked about sustainment of CMMC 
certification during the three-year certificate validity period. They 
wanted to know how sustainment will be monitored and whether 
demonstrating continuous monitoring capabilities would be considered in 
lieu of a strict three-year recertification period. There were also 
questions about what the criteria or triggers would be that would lead 
to a loss of accreditation during this period, including what happens 
when a company with a certification is acquired by another company, and 
whether contractors are required to notify the DoD if systems fall out 
of compliance with CMMC requirements.
    Response: The validity period is one (1) year for CMMC Level 1 and 
three (3) years for CMMC Levels 2 and 3. Contractors must continue to 
meet CMMC requirements during the period of performance of the 
contract. Under CMMC, contractors must submit affirmations into SPRS 
for each assessment, attesting that they have met the CMMC requirements 
and will maintain the applicable information systems at the required 
CMMC level as specified in Sec.  170.22. Monitoring contractor 
compliance with the terms of the contract is the responsibility of the 
contractor, with the government contracting officer. DoD is not 
utilizing a continuous monitoring capability in lieu of compliance 
requirements. DoD understands that information systems operating in a 
CMMC Assessment Scope will require upgrades and maintenance. For 
systems certified at CMMC Level 2 or above, a plan for addressing 
deficiencies is defined in Sec.  170.21.
    It is possible for an organization to need a new assessment during 
the validity period. CMMC self-assessments and certifications are valid 
for a defined CMMC Assessment Scope. If the CMMC Assessment Scope 
changes due to infrastructure modifications or expansion of the CMMC 
Assessment Scope due to new acquisition, a new assessment may be 
required. The original CMMC certification remains valid for the 
original CMMC Assessment Scope. The information system(s) in the new 
CMMC Assessment Scope may not be used to process, store, or transmit 
CUI for any contract until it is validated via a new CMMC assessment. 
The same applies to the annual affirmations. During the annual 
affirmation process, a senior organization official affirms that the 
organization is satisfying and will maintain the requirements of the 
specified CMMC level (e.g., CMMC Level 2 Self-Assessment). The 
affirmation applies to the CMMC Assessment Scope. At the time of a new 
self-assessment or certification, a new affirmation is submitted into 
SPRS affirming that the organization meets the CMMC requirements and 
will maintain the applicable information system (within the CMMC 
Assessment Scope) at the required CMMC level. For CMMC Levels 2 and 3, 
an affirmation is required to be submitted in SPRS annually for the 
duration of the triennial validity period and at the conclusion of any 
POA&M closeout assessments. Affirmation requirements are set forth in 
Sec.  170.22.

14. CMMC Assessment Timeline

    Comment: Several comments requested details about CMMC assessment 
timelines, including how long an assessment would take, how long after 
an assessment was completed would the assessment report be ready, and 
when SPRS content would be updated. One commenter wanted to know how 
soon after a failed assessment a subsequent assessment could be 
scheduled. One commenter wanted details about the remediation period.
    Response: The actual length of time it takes for an OSA to prepare 
for, and assessors to conduct an assessment and prepare the assessment 
report depends on many factors, including the number of systems and 
networks in the CMMC Assessment Scope, the level of assessment being 
conducted, staff preparedness for assessor questions, and the number of 
assessors conducting the assessment.
    For CMMC assessments, C3PAOs will upload the results of the 
assessment and the signed CMMC certificate into the CMMC instantiation 
of eMASS. Certification is automatically posted to SPRS. There is no 
minimum time to wait after a failed assessment before scheduling 
another assessment.
    A NOT MET requirement may be re-evaluated during the course of the 
assessment and for 10 business days following the active assessment 
period under certain conditions, as set forth in Sec.  170.17(c)(2) and 
Sec.  170.18(c)(2). A Level 2 or Level 3 conditional assessment and 
associated POA&M must be closed out within 180 days.

15. Assessment Delays and Award Impact

    Comment: Several commenters expressed concerns about the impact 
that delays in the assessment process would have on contract award. For 
example, if an assessment is held up, by no fault of the contractor, 
such that the results will not be available until after the award date, 
will the contractor be ineligible to receive the award or is there a 
process for delaying the award? Would the answer be the same for a 
reassessment of a contractor whose three-year assessment or certificate 
is expiring? On a related issue, one comment asked about the timing of 
reassessment/recertification and whether work on an existing contract 
can continue after an assessment/certificate has expired if the 
reassessment is scheduled but delayed.
    Response: The CMMC Program rule does not provide mitigations for 
assessment delays that may impact timeliness of certification or 
recertification with regard to the closing date of a particular 
solicitation. Offerors will be required to attain CMMC certification, 
when applicable, at or

[[Page 89073]]

above the level in the solicitation, by the time of award (or option 
period exercise) and must maintain their CMMC status throughout the 
life of the contract, task order, or delivery order. The three-year 
validity period should provide adequate time to prepare for and 
schedule subsequent assessments for certification. Timelines for 
meeting CMMC requirements for Level 1 or 2 self-assessment are within 
the control of the contractor.

16. Defense Contractor and Subcontractor Engagement

    Comment: Several commenters suggested that defense contractors and 
subcontractors should be more engaged in the formulation of the rule 
and better informed in how the rule will be applied. They indicated 
that guidance is unclear, ad hoc, and inconsistent, and requested an 
authoritative source of information, such as FAQs, that are kept up to 
date and provide reliable responses to questions. They also expressed a 
desire for more transparency in how ambiguities are being resolved in 
early assessments.
    Response: In September 2019, the CMMC PMO released the first draft 
publication of the CMMC Model v 0.4. The CMMC PMO received over 2,000 
comments from individuals and industry associations. These comments 
informed changes included in CMMC Model 1.0 released in January 2020. 
In addition, DFARS Case 2019-D041 generated over 750 additional public 
comments that informed changes to the rule text and influenced the 
transition to CMMC 2.0. The Office of the Under Secretary of Defense 
for Acquisition and Sustainment (OUSD(A&S)) held over 100 industry 
listening sessions in 2020 and 2021, engaged with the DIB through 
briefings and discussions with defense industry trade associations, 
academia, and government-based organizations with industry members 
(e.g., National Industrial Security Program Policy Advisory Committee). 
Many sessions were recorded and shared with the public on the internet 
in social media, news releases, and the CMMC PMO website (<a href="https://DoDcio.defense.gov/CMMC/">https://DoDcio.defense.gov/CMMC/</a>), which was completely updated in 2021 and 
contains new information, FAQs, and allows the public direct contact 
with the CMMC PMO. As always, FAQs are to clarify content only, and do 
not interpret, define, or otherwise change the meaning of the 
regulatory text. The CMMC PMO continues to communicate with defense 
contractors and subcontractors, to include small businesses, and other 
members of the public.
    The official website of the DoD CMMC Program is <a href="https://DoDcio.defense.gov/CMMC/">https://DoDcio.defense.gov/CMMC/</a>. This website contains links to CMMC documents 
including, but not limited to, the CMMC Model Overview, CMMC Scoping 
Guidance (by level), CMMC Level 1 Self-Assessment Guide, CMMC Level 2 
Assessment Guide, and the CMMC Glossary.

17. C3PAO Consistency

    Comment: One commenter expressed concerns that C3PAOs would not 
conduct CMMC assessments in a uniform manner, leading to inconsistent 
results.
    Response: C3PAOs use only certified CMMC assessors to perform CMMC 
assessments. To ensure assessments are conducted in a uniform manner, 
assessors are trained by certified instructors and required to pass 
CMMC assessor tests before becoming certified. The accredited CAICO 
manage and oversee the training, testing, authorizing, and certifying 
of candidate assessors and instructors. A CAICO must meet the DoD 
requirements set forth in Sec.  170.10 and achieve compliance with ISO/
IEC 17024:2012, Conformity Assessment--General Requirements for Bodies 
Operating Certification of Persons Conformity Assessment.

18. CMMC Cost Impacts

a. CMMC Cost Assumptions and Estimates
    Comment: Several commenters questioned or refuted the cost 
estimates and/or the assumptions and mathematical approach upon which 
the cost estimates were based. Several commenters requested 
clarification around the cited difference in both cost and hours 
between the CMMC certification process and the DoD Assessment process, 
the accounting for completion of NIST SP 800-171 Rev 2 requirements, 
and cost distinction between enterprise and enclave assessments. Two 
commenters stated that the estimated number of subcontractors was low, 
and one commenter suggested that the $5 million threshold for small 
businesses excluded a large number of small businesses from the 
calculations. One commenter asked whether duplication of assessments 
was considered for small businesses who support many prime contractors. 
Additional commenters believed costs were absent from the calculations, 
to include the cost of completing POA&M, management costs for small 
companies to achieve maturity, and costs for international suppliers. A 
number of comments requested additional estimates based on adjustments 
to labor rates for benefits and taxes, each of the assessment levels, 
and small, medium, and large companies. One commenter asked for 
clarification on the calculations used to estimate public savings. One 
commenter questioned why North American Industry Classification System 
(NAICS) code 54715 pertaining to sensitive CUI was not included in the 
calculations.
    Response: The cost estimates and assumptions referenced by the 
commenters pertain to CMMC 1.0 and are not reflective of the changes in 
CMMC, though public comment feedback has been incorporated into the 
cost estimation process for the CMMC Program where appropriate. The 
Department limited estimates for CMMC to those costs associated with 
preparing for, attaining, and publishing results of: (a) CMMC 
compliance via self-assessment for CMMC Levels 1 and 2, and (b) 
certification at CMMC Level 2 through a C3PAO and Level 3 through the 
DoD. Costs for companies to implement information security protections 
to comply with the existing FAR subpart 4.19 to achieve CMMC Level 1, 
and DFARS subpart 204.73 to achieve CMMC Level 2, are distinct from 
costs associated with CMMC assessment processes to verify and attest to 
the corresponding implementation of existing rules. Cost estimates were 
developed for companies to implement security requirements for CMMC 
Level 3. CMMC Level 3 security requirements are defined in table 1 to 
Sec.  170.14(c)(4) CMMC Level 3 Requirements. For the vast majority of 
the DIB, CMMC does not levy additional information security protection 
requirements but is designed to provide increased assurance that 
defense contractors are contract compliant and can adequately protect 
FCI and CUI at a level commensurate with risk, accounting for 
information flow down to its subcontractors in a multi-tier supply 
chain. There is no recognized duplication of assessments for small 
companies that support many primes, because once assessed, an 
organization need only provide evidence of compliance or certification 
to prospective primes in order to satisfy the CMMC requirement in a 
solicitation. When information system or network boundaries differ, an 
additional assessment may apply.
b. CMMC Cost Burden
    Comment: Several commenters suggested that costs were 
underestimated, particularly for small businesses who were perceived to 
be at risk of decreased participation in the

[[Page 89074]]

marketplace due to the cost prohibitive nature of the CMMC requirement. 
Multiple commenters requested additional strategies to mitigate costs, 
including the promotion of new technologies.
    Response: CMMC Levels 1 and 2, which represent the majority of the 
anticipated requirements, does not levy any additional information 
security protection requirements. To address assessment cost concerns, 
CMMC eliminates the third-party assessment requirement at CMMC Level 1 
and permits self-assessment for certain contracts containing a CMMC 
Level 2 requirement. The DoD Office of Small Business Programs, 
available at <a href="https://business.defense.gov/">https://business.defense.gov/</a>, has informational resources 
that may help defray cybersecurity implementation costs by helping 
organizations stay up-to-date with the latest cybersecurity compliance 
and policy best practices.
c. CMMC Cost Effectiveness and Alternatives
    Comment: Two commenters requested that the DoD measure the impact 
of implementing the additional security requirements. One commenter 
suggested an alternative strategy to protect CUI when generated.
    Response: CMMC does not require implementation of any additional 
security protection requirements beyond those identified in current FAR 
clause 52.204-21 and in NIST SP 800-171 Rev 2 for CMMC Levels 1 and 
Level 2, respectively. CMMC Level 3 requirements are new and based upon 
NIST SP 800-172.

19. CMMC Model

a. CMMC Level Requirement Selection
    Comment: Multiple commenters requested clarification about who 
selects the CMMC Level that is specified in a solicitation and the 
criteria used. Commenters also wanted to know if the contractor's CMMC 
Level flows-down directly to subcontracts and if so, whether that level 
carries down to lower tier subcontracts. Numerous questions asked if 
the government or a contractor is responsible for determining the 
appropriate CMMC Level to include in a subcontract and, if it is the 
contractor's responsibility, what criteria is used to identify the 
appropriate level to flow-down. To that end, commenters requested 
guidance for identifying CUI and information sensitivity. One commenter 
asked for clarification on whether different CMMC Level requirements 
could be identified within a single Statement of Work (SOW).
    Response: The solicitation will specify the required CMMC Level, 
and the level itself will be identified by the requiring activity. The 
requiring activity knows the type and sensitivity of information that 
will be shared with or developed by the awarded contractor and selects 
the CMMC Level required to protect the information according to DoD 
guidance. Contractors must have achieved this level, or higher, to be 
awarded the resultant contract. For subcontracts, the prime contractor 
will identify for its subcontractor the required CMMC Level in 
accordance with Sec.  170.23 if it is not already defined in the 
solicitation. If a prime contractor is uncertain about the appropriate 
CMMC Level to assign when creating a subcontract solicitation, it 
should consult with the government program office to determine what 
type of certification or assessment will be required given the 
information that will flow down. Policies for identification and clear 
marking of CUI materials are provided in CUI program materials and 32 
CFR part 2002, when applicable. A solicitation may contain requirements 
for multiple CMMC Levels if, in support of the contract, different 
enclaves are expected to process, store, or transmit information that 
needs different levels of security.
b. Model Standard, CMMC Levels, and Model Updates
    Comment: One commenter stated that the CMMC Model is not a 
configuration-controlled standard managed by a recognized standards 
body.
    Response: This rule codifies the CMMC Program, elements of which 
are reflected in the CMMC Model. All CMMC Model requirements are 
derived from FAR 52.204-21, NIST SP 800-171 Rev 2, and NIST SP 800-172, 
which are configuration-controlled guidelines managed by NIST. As a 
result of the alignment of CMMC to NIST guidelines, the Department's 
requirements will continue to evolve as changes are made to the 
underlying NIST SP 800-171 Rev 2 and NIST SP 800-172 security 
requirements. Additional rulemaking may be necessary in the future to 
conform CMMC requirements described in this rule to any changes to the 
underlying information protection requirements defined in the 
foundational NIST guidelines.
    Comment: Many comments were received requesting changes to CMMC 
Model 1.0. Several commenters requested changes to CMMC Level 
requirements and others had questions about the content and handling of 
CMMC Model updates. A few commenters made suggestions for restricting 
the current implementation, such as using only NIST SP 800-171 Rev 2 
for the CMMC 1.0 implementation of Level 1-3 requirements and 
supplementing with additional requirements only in Levels 4 and 5. 
Similar comments recommended using NIST SP 800-171 Rev 2 for the 
initial CMMC rollout and later expanding to include additional CMMC 
requirements. A number of comments questioned the purpose and use of 
the CMMC 1.0 implementation of CMMC Level 2. Other comments requested 
information on updating CMMC requirements as new technology and threats 
emerge and new versions of NIST SP 800-171 Rev 2 and NIST SP 800-53 are 
released. Multiple comments were received on CMMC 1.0 Levels 4 and 5. 
Several commenters believed there to be a significant disconnect 
between NIST SP 800-171B/172 and CMMC 1.0 Levels 4 and 5, and issues 
with implementation of these levels. Many comments requested that 
Levels 4 and 5 be updated to allow for flexibility in implementation 
rather than require all the requirements as written. Reasons cited for 
allowing flexibility include reducing cost and assessment complexity as 
well as allowing for the ability to adapt based on architectural 
environments and dynamic threat models.
    Response: Changes were made in this rule to requirements in the 
former CMMC model based in part upon receipt of informal public 
comment. The CMMC Model was streamlined to three-tiers, which align to 
the protection requirements set forth in FAR 52.204-21, NIST SP 800-171 
Rev 2, and NIST SP 800-172, and all CMMC-unique requirements and 
process maturity elements have been removed.
    The CMMC Model and program requirements will be evaluated as new 
technology and threats emerge and revised as appropriate.
    Comment: One comment included a request to identify instances where 
contractors would be better off using a classified environment, rather 
than CMMC version 1.0 Level 4 or 5, to protect the information.
    Response: The CMMC Program is designed to enforce protection of 
unclassified information, to include FCI and CUI, not intended for 
public release that is shared by the Department with its contractors 
and subcontractors. The program provides the Department increased 
assurance that contractors and subcontractors are meeting the 
cybersecurity requirements that apply to acquisition programs and 
systems that process federal contract information and controlled 
unclassified information.

[[Page 89075]]

Any discussion regarding the use of classified networks is outside of 
the scope of the CMMC Program.

20. CMMC Requirements

    Comment: There were multiple comments suggesting additions, 
deletions, or changes to model requirements. One commenter noted 
multiple instances of CMMC requirements with the term `information 
system' rather than `system' used in NIST SP 800-171 Rev 2, asking if 
CMMC meant to change the intent by inserting `information' in these 
requirements. Multiple commenters questioned the intent, clarity, or 
interpretation of several CMMC requirements/NIST SP 800-171 Rev 2 
requirements, recommending clarification regarding vulnerability 
management, protection of mobile devices, review of audit logs, 
disabling of identifiers, FIPS validated encryption, and malicious code 
scans. One comment suggested that CMMC 1.0 requirements RM.2.141 and 
RM.3.144 are redundant and recommended incorporating RM 3.146 into 
CA.2.159, justifying that a plan of action is essentially a risk 
management plan. Two commenters noted that two CMMC 1.0 requirements 
(RE.2.137 and RE.3.139) are unclear as they do not specify what data 
requires backup, or the meaning of resilient backup. One commenter said 
that CMMC 1.0 requirement MA.2.114 removed the qualifier of 
``maintenance'' when describing personnel requiring supervision of 
maintenance activities, asking if this is an insignificant change to 
the NIST SP 800-171 Rev 2 security requirement, or whether there is 
some rationale or message that the CMMC specification is trying to 
adjust by deviating from the NIST SP 800-171 Rev 2. Two commenters 
stated that CMMC 1.0 requirement MP.1.1.18 requires only FCI be 
sanitized, but, for CMMC 1.0 Level 3 (CMMC Level 2 under CMMC 2.0) 
assessments, there is no requirement to sanitize CUI. One commenter 
wanted to know which CMMC requirement requires a medium assurance 
certificate for reporting cyber incidents.
    Response: In CMMC 1.0, there was no intent to change the meaning of 
NIST requirements except those referenced as ``modified.'' These minor 
discrepancies are now resolved as all FCI requirements use the exact 
FAR language and all CUI requirements use the exact language from the 
relevant NIST guidelines. The requirements in CMMC Level 3 are derived 
from NIST SP 800-172 with DoD-approved parameters. Commenters 
requesting revisions to NIST guidelines should respond to the NIST 
public comment periods. There is no CMMC-specific cyber incident 
reporting requirement or need for associated medium assurance 
certificate.
    Comment: Several comments sought clarification on the alignment and 
relative authority or precedence of the CMMC requirements to Federal, 
Legislative, Statutory, Regulatory, or DoD Organizational policy, DoD 
instructions, and FAQs.
    Response: The CMMC Program requirements will be required once 
implemented in the DFARS and will have the same relative authority of 
any other DoD contract requirement. The CMMC Program relates to and 
incorporates elements of the following authorities: Executive Order No. 
13556, Controlled Unclassified Information, 75 FR 68675 (November 4, 
2010), which establishes ``an open and uniform program for managing 
[unclassified] information that requires safeguarding or dissemination 
controls;'' 32 CFR part 2002, which describes the executive branch's 
Controlled Unclassified Information Program and establishes policy for 
designating, handling, safeguarding, and decontrolling information that 
qualifies as CUI when processed, stored, or transmitted on a federal or 
non-federal information system; FAR clause 52.204-21, Basic 
Safeguarding of Covered Contractor Information Systems, which, as 
applicable, requires contractors to apply certain basic safeguarding 
procedures on covered contractor information systems that process, 
store, or transmit FCI; and DFARS clause 252.204-7012, Safeguarding 
Covered Defense Information and Cyber Incident Reporting, which, as 
applicable, requires defense contractors to implement NIST SP 800-171 
Rev 2 requirements on unclassified covered contractor information 
systems that process, store, or transmit covered defense information. 
Additional DoD instructions and manuals address DoD information 
security policy, including DoDI 5200.48 CUI which establishes policy, 
assigns responsibilities, and prescribes procedures for CUI throughout 
the DoD for federal and on non-federal information systems to include 
the implementation of NIST SP 800-171 Rev 2. A requirement for CMMC 
assessments provides DoD assurance that contractors have implemented 
required cybersecurity protections. The requirements of this rule will 
be implemented in an associated 48 CFR acquisition rule regarding CMMC.

21. CMMC Assessment

    Comment: Multiple commenters pointed out that the rule does not 
specify an authoritative source for obtaining a CMMC certificate, 
leaving the pedigree of certificates in question. Two comments inquired 
about the security of record [data] collection and retention and 
whether the assessors' platforms would need to be CMMC Level 3 
compliant to protect sensitive data used for the assessment/
certification process.
    Response: The processes for achieving compliance with a CMMC level 
are described in Sec.  170.15 through Sec.  170.18. CMMC Level 2 
Certification Assessments are conducted by C3PAOs authorized by the 
CMMC Accreditation Body. C3PAOs grant CMMC Level 2 certificates of 
assessment. The DoD conducts CMMC Level 3 Certification Assessments and 
grants Level 3 certificates of assessment. A C3PAO's IT infrastructure 
must achieve at least a CMMC Level 2 Certification Assessment. 
Certified CMMC Assessors working at their place of business or from 
home must use their C3PAO's IT infrastructure. Assessment data and 
results are securely uploaded by the C3PAO into the CMMC instantiation 
of eMASS. The CMMC instantiation of eMASS automatically feeds 
compliance data into SPRS. Both eMASS and SPRS are Department owned and 
operated systems.
    Comment: A few commenters requested resources for understanding 
CMMC requirements. There were also many comments related to the 
purpose, status, schedule, or content of the CMMC Assessment Guides. 
Additional comments requested clarification on the evaluation criteria 
and evidence described in the current Assessment Guides.
    Response: CMMC Assessment Guides are optional resources to aid in 
understanding CMMC requirements and are largely derived from NIST 
documentation, to include NIST SP 800-171 Rev 2 and NIST SP 800-172. 
The CMMC assessment process is defined in Sec.  170.15 through Sec.  
170.18, and the CMMC Scoring Methodology is defined in Sec.  170.24. 
The evaluation criteria (i.e., assessment procedures) and evidence 
(i.e., potential assessment methods and objects) required are taken 
directly from the NIST documentation, and revisions to NIST 
documentation are outside the scope of this rule. The CMMC Assessment 
Guides provide supplementary information, further discussion, examples, 
and references for assessors and contractors preparing for assessments. 
The guides do not identify

[[Page 89076]]

specific solutions or baselines. These documents are available at: 
<a href="https://DoDcio.defense.gov/CMMC/">https://DoDcio.defense.gov/CMMC/</a>. Updated CMMC Assessment Guides and 
associated CMMC documents were posted on the OUSD(A&S) CMMC website 
after the public comment period for DFARS Case 2019-D041 closed on 
November 30, 2020. These documents reflected changes based on review of 
public comments. Future updates to CMMC guidance documentation will be 
made as needed.
    Comment: One comment suggested that audit standards be determined 
for CMMC assessments. Two comments asked for clarification regarding 
references provided in the model, whether all references must be 
reviewed, and if the requirements within the references must also be 
achieved.
    Response: The Department has reviewed definitions of audit and 
assessments and determined ``assessment'' best meets the goals of the 
CMMC Program. The cybersecurity standard requirements for the different 
CMMC Levels are set forth in Sec.  170.14 and clarify references for 
the security requirements.
    Comment: Many commenters were concerned about the lack of waivers 
or POA&Ms. Several commenters commented that not allowing waivers is 
impractical and will impact the ability of businesses to qualify for 
contract award. Commenters asked for clarification on the differences 
between POA&M that are not allowed by CMMC and the plans of action as 
required in the CMMC Level 3 control (now CMMC Level 2 under CMMC 2.0), 
CA.2.159 (now CA.L2-3.12.2 under CMMC 2.0). Many noted that POA&Ms are 
necessary when managing activities like system upgrades, vendor 
changes, and company acquisitions to avoid temporarily falling out of 
compliance.
    Response: Under certain circumstances, the CMMC Program does permit 
contract award to organizations that have an approved and time limited 
POA&M. See Sec.  170.21 for additional information on POA&Ms. There is 
no process for organizations to request waiver of CMMC solicitation 
requirements. DoD internal policies, procedures, and approval 
requirements will govern the process for DoD to waive inclusion of the 
CMMC requirement in the solicitation.

22. The Accreditation Body and C3PAOs

    Comment: Many commenters had questions and concerns about the 
management of the Accreditation Body and C3PAOs. A few commenters 
suggested using a government entity instead of the Accreditation Body 
construct to manage assessments. Commenters asked about the governance, 
resourcing, and oversight of the Accreditation Body with respect to 
CMMC training and assessments. Commenters expressed concerns such as 
who would make final decisions about CMMC issues, the lack of clearly 
defined roles and responsibilities for CMMC governance, and the long-
term effectiveness of the Accreditation Body staffed by an all-
volunteer workforce. One comment asked how the Accreditation Body can 
legally license training when CMMC Program information is available for 
free.
    Response: The decision to use a non-governmental Accreditation Body 
was made because the DoD determined that there was insufficient 
capacity within the DoD to manage assessor training and assessments for 
all defense contractors who need to comply with CUI protection 
policies. The DoD CMMC PMO provides oversight of the Accreditation Body 
and is also responsible for developing, updating, maintaining, and 
publishing the CMMC Model, CMMC Assessment Guides, and policies for 
implementation of the CMMC Program.
    Roles and responsibilities of the CMMC PMO, the Accreditation Body, 
and its organizations are described in SUBPART C of this rule. The 
Accreditation Body accredits C3PAOs and the CAICO. The Accreditation 
Body authorizes the CAICO to certify CMMC assessors and instructors and 
the C3PAOs to conduct assessments using CAICO-certified assessors.
    Comment: Many commenters expressed concerns about how to ensure the 
necessary independence, quality assurance, integrity, and rigor of, and 
protection against potential conflicts of interest within the 
Accreditation Body and C3PAOs. Numerous commenters recommended the use 
of ISO/IEC standards to address these issues. Additionally, one 
commenter was concerned about high costs for assessments that could 
result if there is a lack of oversight for charging fees.
    Response: The Accreditation Body is required to become compliant 
with the ISO/IEC 17011:2017 standard (the international benchmark used 
in demonstrating an accreditation body's impartiality, technical 
competency, and resources) and the requirements set forth in Sec.  
170.8. Additionally, the C3PAOs and CAICO must comply with requirements 
as specified in Sec.  170.9 and Sec.  170.10, respectively, including 
the specified ISO/IEC standards.
    Comment: To address a perceived shortage of CMMC C3PAO assessors, 
two commenters suggested authorizing the use of other ISO/IEC-compliant 
accreditation bodies to increase the numbers of assessors. Another 
commenter wanted to know how a company could become an accreditation 
body.
    Response: Consistency in training is imperative due to the unique 
qualifications needed to understand requirements. Additionally, ISO/IEC 
17024:2012 Conformity Assessment requirements are levied against the 
CAICO and may not be required by other entities. The number and level 
of assessors needed is relative to the number of companies seeking CMMC 
assessment. The demand level is influenced, but not solely determined 
by, the number of solicitations that include CMMC requirements, the 
CMMC Levels specified, and the estimated number of subcontractors that 
will also need to meet CMMC requirements, when flowed down by the prime 
contractor. To facilitate a smooth and orderly transition to CMMC, the 
Department will issue policy guidance to government Program Managers to 
govern the rate at which CMMC requirements are levied in new 
solicitations. The implementation phases are described in Sec.  
170.3(e). The CMMC PMO has visibility into the Accreditation Body's 
assessor training activities, tracks the anticipated number of trained 
assessors, and will use this information to inform policies that guide 
government Program Managers in identifying CMMC requirements in new 
solicitations.

23. Relationship to Existing Regulations

    Comment: Several commenters asked about the implications of having 
DFARS clauses 252.204-7012 and 252.204-7021 coexist in contracts and 
wanted to know if all the 252.204-7012 requirements, including the 
requirements for ``adequate security,'' incident reporting, and flow-
down, apply in the presence of 252.204-7021. Others were concerned 
about a perceived conflict on the protection of CUI between NIST SP 
800-171 Rev 2, which specifies the minimum requirements to provide 
``adequate security'' for CUI on nonfederal systems and DFARS clause 
252.204-7021 based on the CMMC Program. Multiple commenters wanted to 
know if the 252.204-7021 clause and the CMMC requirements override 
contractor responsibility to comply with other applicable clauses of 
the contract, or other applicable U.S. Government statutory or 
regulatory requirements. Others were concerned about a

[[Page 89077]]

continued proliferation of security requirements.
    Response: CMMC Program requirements proposed in this rule will be 
implemented in the DFARS, as needed, which may result in changes to 
current DoD solicitation provisions and contract, including DFARS 
clause 252.204-7021. As such, DoD cannot address applicability of or 
changes to current DFARS clause 252.204-7021 or other current DFARS 
cybersecurity provisions or clauses at this time.
    DoD does not intend to impose duplicative cybersecurity protection 
or assessment requirements. There is no conflict between the CMMC 
cybersecurity protection requirements described in this rule and DoD's 
current information safeguarding requirements, including those set 
forth in DFARS clause 252.204-7012. This CMMC rule adds new 
requirements for the assessment of contractor implementation of 
underlying information security standards and guidelines, as 
applicable, such as those set forth in FAR clause 52.204-21 and in the 
NIST SP 800-171 Rev 2. This rule also prescribes additional information 
security protection and assessment requirements for CMMC Level 3, 
derived from NIST SP 800-172, for certain limited scenarios.
    As new cyber threats emerge, security requirements will continue to 
evolve to support efforts to protect information important to U.S. 
national security. However, alternate standards will continue to be 
reviewed, as described in Sec.  170.20, to minimize the burden of new 
requirements.

24. Phase-Out of Existing Cybersecurity Requirements

    Comment: Several commenters asked whether DFARS clause 252.204-
7012, DFARS provision 252.204-7019 and 252.204-7020 will be phased out 
since DFARS clause 252.204-7021 is now a requirement.
    Response: The CMMC Program requirements proposed in this rule will 
be implemented in the DFARS, as needed, which may result in changes to 
current DoD solicitation provisions and contract clauses, including 
DFARS clause 252.204-7021. As such, DoD cannot address applicability of 
or changes to current DFARS clause 252.204-7021 or other current DFARS 
cybersecurity provisions or clauses at this time.
    The information safeguarding requirements and cyber incident 
reporting requirements set forth in DFARS clause 252.204-7012 will not 
be phased out as a result of this rule. CMMC Program requirements 
provide DoD with verification, through self or third-party assessment, 
that defense contractors have, in fact, implemented DoD's cybersecurity 
protection requirements.
    In addition, the requirements of this rule will not be fully 
implemented (and will not appear in all DoD contracts) until 2026 or 
later. As such, DoD will continue to require the current cybersecurity 
protections as reflected in the identified DFARS provisions and clauses 
for contracts that do not include a CMMC requirements.

Applicability

    The CMMC Program will require DoD to identify CMMC Level 1, 2, or 3 
as a solicitation requirement for any effort that will cause a 
contractor or subcontractor to process, store, or transmit FCI or CUI 
on its unclassified information system(s). Once CMMC is implemented in 
48 CFR, DoD will specify the required CMMC Level in the solicitation 
and the resulting contract.
    Summary of Program Changes: DFARS Case 2019-D041 implemented DoD's 
original model for assessing contractor information security 
protections, which is referred to as ``CMMC 1.0.'' CMMC 1.0 was 
comprised of five progressively advanced levels of cybersecurity 
standards and required defense contractors and subcontractors to 
undergo a certification process to demonstrate compliance with the 
cybersecurity standards associated with a given CMMC Level.
    In March 2021, the Department initiated an internal review of 
CMMC's implementation that engaged DoD's cybersecurity and acquisition 
leaders to refine policy and program implementation, focusing on the 
need to reduce costs for small businesses and align cybersecurity 
requirements to other federal standards and guidelines. This review 
resulted in CMMC 2.0, which streamlines assessment and certification 
requirements and improves implementation of the CMMC Program. These 
changes include:
    <bullet> Eliminating Levels 2 and 4, and renaming the remaining 
three CMMC Levels as follows:
    <bullet> Level 1 will remain the same as CMMC 1.0 Level 1;
    <bullet> Level 2 will be similar to CMMC 1.0 Level 3;
    <bullet> Level 3 will be similar to CMMC 1.0 Level 5.
    <bullet> Removing CMMC-unique requirements and maturity processes 
from all levels;
    <bullet> For CMMC Level 1, allowing annual self-assessments with an 
annual affirmation by company leadership;
    <bullet> Allowing a subset of companies at Level 2 to demonstrate 
compliance through self-assessment rather than C3PAO assessment.
    <bullet> For CMMC Level 3, requiring Department-conducted 
assessments; and
    <bullet> Developing a time-bound and enforceable POA&M process.
    The CMMC Program will be implemented through publication of rules 
for both title 32 CFR and title 48 CFR. Both rules will have public 
comment periods.

Background

A. Statement of Need for This Rule

    The Department of Defense (DoD) requires defense contractors to 
protect sensitive unclassified information in accordance with 
requirements for FCI and CUI. To verify contractor and subcontractor 
implementation of DoD's cybersecurity information protection 
requirements, the Department developed the Cybersecurity Maturity Model 
Certification (CMMC) Program as a means of assessing and verifying 
adequate protection of contractor information systems that process, 
store, or transmit either FCI or CUI.
    The CMMC Program is intended to: (1) align cybersecurity 
requirements to the sensitivity of unclassified information to be 
protected, (2) add a self-assessment element to affirm implementation 
of applicable cybersecurity requirements, (3) add a certification 
element to verify implementation of cybersecurity requirements, and (4) 
add an affirmation to attest to continued compliance with assessed 
requirements. As part of the program, DoD also intends to provide 
supporting resources and training to the DIB, to help support companies 
who are working to achieve the required CMMC level. The CMMC Program 
provides for assessment at three levels, starting with basic 
safeguarding of FCI at CMMC Level 1, moving to the broad protection of 
CUI at CMMC Level 2, and culminating with higher-level protection of 
CUI against risk from Advanced Persistent Threats (APTs) at CMMC Level 
3.
    The CMMC Program addresses DoD's need to protect its sensitive 
unclassified information during the acquisition and sustainment of 
products and services from the DIB. This effort is instrumental in 
establishing cybersecurity as a foundation for DoD acquisitions.
    Although DoD contract requirements to provide adequate security for 
covered defense information (reflected in DFARS clause 252.204-7012) 
predate CMMC by many years, a certification requirement for the 
handling of CUI to

[[Page 89078]]

assess a contractor or subcontractor's implementation of those required 
information security controls is new with the CMMC Program.
    The theft of intellectual property and sensitive information from 
all U.S. industrial sectors from malicious cyber activity threatens 
economic security and national security. The Council of Economic 
Advisers estimates that malicious cyber activity cost the U.S. economy 
between $57 billion and $109 billion in 2016.\19\ The Center for 
Strategic and International Studies estimates that the total global 
cost of cybercrime was as high as $600 billion in 2017.\20\
---------------------------------------------------------------------------

    \19\ Based on information from the Council of Economic Advisors 
report: The Cost of Malicious Cyber Activity to the U.S. Economy, 
2018.
    \20\ Based on information from the Center for Strategic and 
International Studies report on the Economic Impact of Cybercrime; 
<a href="https://www.csis.org/analysis/economic-impact-cybercrime">https://www.csis.org/analysis/economic-impact-cybercrime</a>.
---------------------------------------------------------------------------

    Malicious cyber actors have targeted and continue to target defense 
contractors and the DoD supply chain. These attacks not only focus on 
the large prime contractors, but also target subcontractors that make 
up the lower tiers of the DoD supply chain. Many of these 
subcontractors are small entities that provide critical support and 
innovation. Overall, the DIB sector consists of over 220,000 companies 
\21\ that process, store, or transmit CUI or FCI in support the 
warfighter and contribute towards the research, engineering, 
development, acquisition, production, delivery, sustainment, and 
operations of DoD systems, networks, installations, capabilities, and 
services. The aggregate loss of intellectual property and controlled 
unclassified information from the DoD supply chain can undercut U.S. 
technical advantages and innovation, as well as significantly increase 
the risk to national security. As part of multiple lines of effort 
focused on the security and resiliency of the DIB, the Department is 
working with industry to enhance the protection of FCI and CUI within 
the DoD supply chain. Toward this end, DoD has developed the CMMC 
Program.
---------------------------------------------------------------------------

    \21\ Based on information from the Federal Procurement Data 
System, the average number of unique prime contractors is 
approximately 212,650 and the number of known unique subcontractors 
is approximately 8,300. (FPDS from FY18-FY21).
---------------------------------------------------------------------------

Cybersecurity Maturity Model Certification Program
    The CMMC Program provides a comprehensive and scalable 
certification approach to verify the implementation of requirements 
associated with the achievement of a cybersecurity level. CMMC is 
designed to provide increased assurance to the Department that defense 
contractors can adequately protect FCI and CUI at a level commensurate 
with the risk, accounting for information flow down to its 
subcontractors in a multi-tier supply chain. Defense contractors can 
achieve a specific CMMC Level for its entire enterprise network or an 
enclave(s), depending upon where the information to be protected is 
processed, stored, or transmitted.
    The CMMC Program assesses implementation of cybersecurity 
requirements. The CMMC requirements for safeguarding and security are 
the same as those required by FAR Subpart 4.19 and DFARS Subpart 
204.73, as well as selected NIST SP 800-172 requirements. CMMC Level 1 
requires implementation of the safeguarding requirements set forth in 
FAR clause 52.204-21. CMMC Level 2 requires implementation of the 
security requirements in NIST SP 800-171 Rev 2. CMMC Level 3 requires 
implementation of the security requirements in NIST SP 800-171 Rev 2 as 
well as selected NIST SP 800-172 requirements, with DoD specified 
parameters. The CMMC requirements for all three Levels are provided in 
Sec.  170.14. In general, CMMC assessments do not duplicate efforts 
from existing DoD assessments. In rare circumstances a re-assessment 
may be necessary when cybersecurity risks, threats, or awareness have 
changed.
    Under the CMMC Program, CMMC contract requirements include self-
assessments and third-party assessments for CMMC Level 2, predicated on 
program criticality, information sensitivity, and the severity of cyber 
threat. Based on the type and sensitivity of the information to be 
protected, a defense contractor must achieve the appropriate CMMC Level 
and demonstrate implementation of the associated set of information 
protection requirements.
    If CMMC Level 1 or Level 2 Self-Assessment is a contract 
requirement, the defense contractor will be required to self-assess its 
compliance with the CMMC Level 1 or Level 2 requirements and submit the 
assessment results and an affirmation of conformance in SPRS. CMMC 
Level 1 self-assessment and associated affirmation is required 
annually. CMMC Level 2 Self-Assessment is required triennially with an 
affirmation following self-assessment and annually thereafter.
    If CMMC Level 2 Certification Assessment is a contract requirement, 
CMMC assessments must be performed by an authorized or accredited CMMC 
Third Party Assessment Organization (C3PAO). When CMMC Level 3 
Certification Assessment is a contract requirement, an assessment by 
DoD is required following a CMMC Level 2 Final Certification 
Assessment. Upon completion of a CMMC Level 2 or 3 Certification 
Assessment, the offeror may be granted a certification of assessment 
based on the results of the assessment at the appropriate CMMC Level 
(as described in the CMMC Model). The assessment results are documented 
in SPRS to enable contracting officers to verify the validity status of 
an offeror's certification level and currency (i.e., not more than 
three years old) prior to contract award. The offeror must also submit 
an affirmation of conformance in SPRS following the assessment and 
annually thereafter.
    CMMC allows the use of a Plan of Action and Milestones (POA&Ms) for 
specified CMMC Level 2 and 3 security requirements. Each POA&M must be 
closed, i.e., all requirements completed, within 180 days of the 
initial assessment.
    The details of the requirements for self-assessment, third-party 
assessment, and affirmation for each CMMC Level, are provided in Sec.  
170.15 through Sec.  170.18. POA&M requirements, including which 
requirements are allowed to be on a POA&M and POA&M closeout 
requirements, in addition to requirements for provision of an 
affirmation at closeout, contract eligibility, and continuation are 
provided in Sec.  170.21 and Sec.  170.22.
    DoD's phased implementation of CMMC requirements is described in 
Sec.  170.3(e). Once CMMC requirements have been implemented in the 
DFARS, the solicitation will identify the specific CMMC Level required 
for that procurement. To implement a phased transition, selection of a 
CMMC Level will be based upon careful consideration of market research 
and the likelihood of a robust competitive market of prospective 
offerors capable of meeting the requirement. In some scenarios, DoD may 
elect to waive application of CMMC third party assessment requirements 
to a particular procurement. In such cases, the solicitation will not 
include a CMMC assessment requirement. Such waivers may be requested 
and approved by the Department in accordance with DoD's internal 
policies and procedures. For a DoD solicitation or contract that does 
include CMMC requirements, including those for the acquisition of 
commercial items (except those exclusively COTS items) valued at 
greater than the micro-purchase threshold, contracting officers will 
not make award, or exercise an option on a contract, if the offeror or

contractor does not meet the requirements for the required CMMC Level. 
Furthermore, CMMC requirements are required to flow down to 
subcontractors as prescribed in the solicitation at all tiers, 
commensurate with the sensitivity of the unclassified information 
flowed down to each subcontractor.

B. Legal Authority

    5 U.S.C. 301 authorizes the head of an Executive department or 
military department to prescribe regulations for the government of his 
or her department, the conduct of its employees, the distribution and 
performance of its business, and the custody, use, and preservation of 
its records, papers, and property. (<a href="https://www.govinfo.gov/content/pkg/USCODE-2009-title5/pdf/USCODE-2009-title5-partI-chap3-sec301.pdf">https://www.govinfo.gov/content/pkg/USCODE-2009-title5/pdf/USCODE-2009-title5-partI-chap3-sec301.pdf</a>).
    Section 1648 of the National Defense Authorization Act for Fiscal 
Year 2020 (Pub. L. 116-92) \22\ directs the Secretary of Defense to 
develop a consistent, comprehensive framework to enhance cybersecurity 
for the U.S. Defense Industrial Base (DIB). The CMMC Program is an 
important part of this framework.

C. Community Impact

    This rule impacts all prospective and actual DoD contractors and 
subcontractors that are handling or will handle DoD information that 
meets the standards for FCI or CUI on a contractor information system 
during performance of the DoD contract or subcontract. This rule also 
impacts all companies who are performing or will perform accreditation, 
training, certification, or assessment functions in connection with 
implementation of the CMMC Program.

D. Regulatory History

    The CMMC Program verifies defense contractor compliance with DoD's 
cybersecurity information protection requirements. It is designed to 
protect sensitive unclassified information that is shared by the 
Department with or generated by its contractors and subcontractors. The 
cybersecurity standards required by the program are the same as those 
set forth in FAR clause 52.204-21 (CMMC Level 1), the NIST SP 800-171 
Rev 2 guidelines, which is presently required by DFARS clause 252.204-
7012 (CMMC Level 2), and additional selected requirements from the NIST 
SP 800-172 guidelines (CMMC Level 3). The program adds a robust 
assessment element and provides the Department increased assurance that 
contractors and subcontractors are meeting these requirements.
    In September 2020, the DoD published an interim rule to the DFARS 
in the Federal Register (DFARS Case 2019-D041), which implemented the 
DoD's initial vision for the CMMC Program (``CMMC 1.0'') and outlined 
the basic features of the program (tiered model, required assessments, 
and implementation through contracts). The interim rule became 
effective on November 30, 2020, establishing a five-year phase-in 
period.
    In March 2021, the Department initiated an internal review of 
CMMC's implementation, informed by more than 750 CMMC-related public 
comments in response to the interim DFARS rule. This comprehensive, 
programmatic assessment engaged cybersecurity and acquisition leaders 
within DoD to refine policy and program implementation.
    In November 2021, the Department announced CMMC 2.0, which 
incorporates an updated program structure and requirements designed to 
achieve the primary goals of an internal DoD review of the CMMC 
Program. With the implementation of the CMMC Program, the Department 
introduced several key changes that build on and refine the original 
program requirements. These include:
    <bullet> Streamlining the model from five to three certification 
levels;
    <bullet> Allowing all companies at Level 1 and a subset of 
companies at Level 2 to demonstrate compliance through self-
assessments;
    <bullet> Increased oversight of professional and ethical standards 
of third-party assessors; and
    <bullet> Allowing companies, under certain limited circumstances, 
to make POA&Ms to achieve certification.
    The CMMC requirements established pursuant to DFARS Case 2019-D041 
have not been revised as of the date of publication of this rule. 
However, the CMMC Program requirements proposed in this rule will be 
implemented in the DFARS, as needed, which may result in changes to the 
current DFARS text, solicitation provisions, and contract clauses 
relating to DoD's cybersecurity protection requirements, including 
DFARS subpart 204.75 and DFARS clause 252.204-7021, Cybersecurity 
Maturity Model Certification (CMMC) Requirements.

Regulatory Impact Analysis

    FAR Subpart 4.19 and DFARS Subpart 204.73 address safeguarding of 
FCI and CUI in contractor information systems and prescribe contract 
clauses requiring protection of FCI and CUI within the supply chain. 
The FAR and DFARS requirements for safeguarding FCI and CUI predate the 
CMMC Program by many years, and baseline costs for their implementation 
are assumed to vary widely based on factors including, but not limited 
to, company size and complexity of the information systems to be 
secured. FAR 52.204-21, Basic Safeguarding of Covered Contractor 
Information Systems, is prescribed at FAR section 4.1903 for use in 
solicitations and contracts when the contractor or subcontractor at any 
tier may have FCI residing in or transiting through its information 
system. This clause requires contractors and subcontractors to apply 
basic safeguarding requirements and procedures to protect applicable 
contractor information systems that process, store, or transmit FCI. In 
addition, DFARS clause 252.204-7012, Safeguarding Covered Defense 
Information and Cyber Incident Reporting, is prescribed at DFARS 
section 204.7304(c) for use in DoD in all solicitations and contracts, 
including solicitations and contracts using FAR part 12 procedures for 
the acquisition of commercial items, except for solicitations and 
contracts solely for the acquisition of commercially available off-the-
shelf items. This clause applies when a contractor information system 
processes, stores, or transmits covered defense information and 
requires contractors and subcontractors to provide ``adequate 
security'' to safeguard that information when it resides on or transits 
through a contractor information system, and to report cyber incidents 
that affect that system or network. The clause states that to provide 
adequate security, the contractor shall implement, at a minimum, the 
security requirements in National Institute of Standards and Technology 
(NIST) Special Publication (SP) 800-171 Rev 2, Protecting CUI in 
Nonfederal Systems and Organizations. Contractors are also required to 
flow down DFARS clause 252.204-7012 to all subcontracts for 
operationally critical support or for which subcontractor performance 
will involve covered defense information.
    However, neither FAR clause 52.204-21 nor DFARS clause 252.204-7012 
provide for DoD assessment of a contractor's implementation of the 
information protection requirements required by those clauses. The 
Department developed the CMMC Program to verify implementation of 
cybersecurity requirements in DoD contracts and subcontracts, by 
assessing

[[Page 89080]]

adequacy of contractor information system security compliance prior to 
award and during performance of the contract. With limited exceptions, 
the Department intends to require compliance with CMMC as a condition 
of contract award. Once CMMC is implemented, the required CMMC Level 
for contractors and subcontractors will be specified in the 
solicitation and Requests for Information (RFIs), if utilized.
    There are three different levels of CMMC assessment, starting with 
basic safeguarding of FCI at Level 1, moving to the broad protection of 
CUI at Level 2, and culminating with higher level protection of CUI 
against risk from Advanced Persistent Threats (APTs) at Level 3. The 
benefits and costs associated with implementing this rule, as well as 
alternative approaches considered, are as follows:

Background

    The Department of Defense (DoD or Department) requires a secure and 
resilient supply chain to ensure the development, production, and 
sustainment of capabilities critical to national security. The DoD 
supply chain is targeted by adversaries with increasing frequency and 
sophistication, and to devastating effect. Therefore, implementation of 
cybersecurity standards and enforcement mechanisms are critically 
important. Executive Order (E.O.) 14028, ``Improving the Nation's 
Cybersecurity,'' emphasizes the need to strengthen cybersecurity 
protections for both the Federal Government and the private sector.
    Nation-state adversaries attack the U.S. supply chain for a myriad 
of reasons, including exfiltration of valuable technical data (a form 
of industrial espionage); disruption to control systems used for 
critical infrastructure, manufacturing, and weapons systems; corruption 
of quality and assurance across a broad range of product types and 
categories; and manipulation of software to achieve unauthorized access 
to connected systems and to degrade the integrity of system operations. 
For example, since September 2020, major cyber-attacks such as the 
SolarWinds,\23\ Colonial Pipeline, Hafnium,\24\ and Kaseya \25\ 
attacks, have been spearheaded or influenced by nation-state actors 
\26\ and resulted in significant failures and disruption. In context of 
this threat, the size and complexity of defense procurement activities 
provide numerous pathways for adversaries to access DoD's sensitive 
systems and information. Moreover, adversaries continue to evolve their 
tactics, techniques, and procedures. For example, on April 28, 2022, 
CISA and the FBI issued an advisory on destructive ``wiperware,'' a 
form of malware which can destroy valuable information.\27\ Protection 
of DoD's sensitive unclassified information is critically important, 
and the DoD needs assurance that contactor information systems are 
adequately secured to protect such information when it resides on or 
transits those systems.

---------------------------------------------------------------------------

    The Department is committed to working with defense contractors to 
protect DoD and defense contractor sensitive unclassified information 
in accordance with requirements for FCI and CUI.
    <bullet> Federal Contract Information (FCI): As defined in section 
4.1901 of the FAR, FCI means information, not intended for public 
release, that is provided by or generated for the Government under a 
contract to develop or deliver a product or service to the Government, 
but not including information provided by the Government to the public, 
such as that on public websites, or simple transactional information, 
such as that necessary to process payments.
    <bullet> Controlled Unclassified Information (CUI): 32 CFR 
2002.4(h) defines CUI, in part, as information the Government creates 
or possesses, or that an entity creates or possesses for or on behalf 
of the Government, that a law, regulation, or Government-wide policy 
requires or permits an agency to handle using safeguarding or 
dissemination controls, including FCI.
    In September 2020, the DoD published DFARS interim rule (Case 2019-
D041), which implemented DoD's initial vision for the Cybersecurity 
Maturity Model Certification (CMMC) Program (``CMMC 1.0'') and outlined 
basic program features, to include: 5-level tiered model, CMMC 
Certified Third Party Assessment Organization (C3PAO) assessments in 
support of contractor and subcontractor certification, with no 
allowance for a Plan of Action and Milestones, and implementation of 
all security requirements by the time of a contract award. A total of 
750 comments were received on the CMMC Program during the public 
comment period that ended on November 30, 2020. These comments 
highlighted a variety of industry concerns including concerns relating 
to the costs for a C3PAO certification, and the costs and burden 
associated with implementing, prior to award, the required process 
maturity and 20 additional cybersecurity practices that were included 
in CMMC 1.0. The Small Business Administration Office of Advocacy also 
raised similar concerns on the impact the rule would have on small 
businesses in the DIB.
    Pursuant to DFARS clause 252.204-7012, DoD has required certain 
defense contractors and subcontractors to implement the security 
protections set forth in the National Institute of Standards and 
Technology (NIST) Special Publication (SP) 800-171 Rev 2 to provide 
adequate security for sensitive unclassified DoD information that is 
processed, stored, or transmitted on contractor information systems and 
to document their implementation status, including any plans of action 
for any NIST SP 800-171 Rev 2 requirement not yet implemented, in a 
System Security Plan. The CMMC Program provides the Department the 
mechanism needed to verify that a defense contractor or subcontractor 
has implemented the security requirements at each CMMC Level and is 
maintaining that status across the contract period of performance, as 
required.
    In calendar year (CY) 2021 DoD paused the planned CMMC rollout to 
conduct an internal review of the CMMC Program. The internal review 
resulted in a refined and streamlined set of requirements that 
addressed many of the concerns identified in the public comments 
received relating to CMMC 1.0. These changes have been incorporated 
into the CMMC Program structure and policies, now referred to as ``CMMC 
2.0.'' In July 2022, the CMMC PMO met with the Office of Advocacy for 
the United States Small Business Administration (SBA) to address the 
revisions planned in CMMC 2.0 that are responsive to prior SBA 
concerns.
    The CMMC Program will enhance the ability of the DoD to safely 
share sensitive unclassified information with

[[Page 89081]]

defense contractors and know the information will be suitably 
safeguarded. Once fully implemented, CMMC will incorporate a set of 
cybersecurity requirements into acquisition contracts to provide 
verification that applicable cyber protections have been implemented. 
Under the CMMC Program, defense contractors and subcontractors will be 
required to implement certain cybersecurity protection requirements 
tied to a designated CMMC level and either perform a self-assessment or 
obtain an independent assessment from either a third-party or DoD as a 
condition of a DoD contract award. CMMC is designed to validate the 
protection of sensitive unclassified information that is shared with 
and generated by the Department's contractors and subcontractors. 
Through protection of information by adherence to the requirements 
verified in CMMC 2.0, the Department and its contractors will prevent 
disruption in service and the loss of intellectual property and assets, 
and thwart access to sensitive unclassified information by the nation's 
adversaries.
    The CMMC Program is intended to: (1) align cybersecurity 
requirements to the sensitivity of unclassified information to be 
protected, and (2) add a certification element, where appropriate, to 
verify implementation of cybersecurity requirements. As part of the 
program, DoD also intends to provide supporting resources and training 
to defense contractors to help support companies who are working to 
achieve the required CMMC level. The CMMC Program provides for 
assessment at three levels: basic safeguarding of FCI at CMMC Level 1, 
broad protection of CUI at CMMC Level 2, and enhanced protection of CUI 
against risk from Advanced Persistent Threats (APTs) at CMMC Level 3. 
The CMMC Program is designed to provide increased assurance to the 
Department that a defense contractor can adequately protect sensitive 
unclassified information (i.e., FCI and CUI) in accordance with 
prescribed security requirements, accounting for information flow down 
to its subcontractors in a multi-tier supply chain.
    The CMMC Program addresses DoD's need to protect its sensitive 
unclassified information during the acquisition and sustainment of 
products and services from the DIB. This effort is instrumental in 
establishing cybersecurity as a foundation for future DoD acquisition.
    Although DoD contract requirements to provide adequate security for 
covered defense information (reflected in DFARS 252.204-7012) predate 
CMMC by many years, a certification requirement for the handling of CUI 
to assess a contractor or subcontractor's compliance of those required 
information security controls is new with the CMMC Program. Findings 
from DoD Inspector General report \28\ indicate that DoD contractors 
did not consistently implement mandated system security requirements 
for safeguarding CUI and recommended that DoD take steps to assess a 
contractor's ability to protect this information. The report emphasizes 
that malicious actors can exploit the vulnerabilities of contractors' 
networks and systems and exfiltrate information related to some of the 
Nation's most valuable advanced defense technologies.
---------------------------------------------------------------------------

    \28\ DODIG-2019-105 ``Audit of Protection of DoD CUI on 
Contractor-Owned Networks and Systems''
---------------------------------------------------------------------------

    Currently, the FAR and DFARS prescribe contract clauses intended to 
protect FCI and CUI. Specifically, the clause at FAR 52.204-21, Basic 
Safeguarding of Covered Contractor Information Systems, is prescribed 
at FAR 4.1903 for use in Government solicitations and contracts when 
the contractor or a subcontractor at any tier may have FCI residing in 
or transiting through its information system(s). This clause requires 
contractors and subcontractors to implement basic safeguarding 
requirements and procedures to protect FCI being processed, stored, or 
transmitted on contractor information systems. In addition, DFARS 
clause 252.204-7012, Safeguarding Covered Defense Information and Cyber 
Incident Reporting, is prescribed at DFARS 204.7304(c) for use in all 
solicitations and contracts except for solicitations and contracts 
solely for the acquisition of commercially available off-the-shelf 
(COTS) items. This clause requires contractors and subcontractors to 
provide ``adequate security'' to process, store or transmit covered 
defense information when it resides on or transits a contractor 
information system, and to report cyber incidents that affect that 
system or network. The clause states that to provide adequate security, 
the contractor shall implement, at a minimum, the security requirements 
in NIST Special Publication (SP) 800-171 Rev 2, Protecting CUI in 
Nonfederal Systems and Organizations. Contractors are also required to 
flow down DFARS clause 252.204-7012 to all subcontracts that require 
processing, storing, or transmitting of covered defense information.
    However, neither FAR clause 52.204-21 nor DFARS clause 252.204-7012 
provide for DoD verification of a contractor's implementation of the 
basic safeguarding requirements specified in FAR 52.204-21 nor the 
security requirements specified in NIST SP 800-171 Rev 2, 
implementation of which is required by DFARS clause 252.204-7012, prior 
to contract award. As part of multiple lines of effort focused on the 
security and resilience of the DIB, the Department is working with 
industry to enhance the protection of FCI and CUI within the DoD supply 
chain. Toward this end, DoD has developed the CMMC Program.

CMMC 2.0 Requirements

    The CMMC Program requirements will be implemented through the DoD 
acquisition and contracting process. With limited exceptions, the 
Department intends to require compliance with CMMC as a condition of 
contract award. Once CMMC is implemented, the required CMMC level for 
contractors will be specified in the solicitation. In accordance with 
the implementation plan described in 32 CFR 170.3(e), CMMC compliance 
or certification requirements will apply to new DoD solicitations and 
contracts, and shall flow down to subcontractors, based on the 
sensitivity of the FCI and CUI to be processed, stored or transmitted 
to or by the subcontractor. Before contract award, the offeror must 
achieve the specified CMMC level for the contractor information system 
(e.g., enterprise network, network enclave) that will process, store, 
or transmit the information to be protected. The contractor or 
subcontractor will also submit affirmations in the Supplier Performance 
Risk System (SPRS). An overview of requirements at each level is shown:

CMMC Level 1 Self-Assessment

    <bullet> CMMC Level 1 Self-Assessment requires compliance with 
basic safeguarding requirements to protect FCI are set forth in FAR 
clause 52.204-21. CMMC Level 1 does not add any additional security 
requirements to those identified in FAR 52.204-21.
    <bullet> Organizations Seeking Assessment (OSAs) will submit the 
following information in SPRS prior to award of any prime contract or 
subcontract and annually thereafter:
    1. the results of a self-assessment of the OSA's implementation of 
the basic safeguarding requirements set forth in 32 CFR 170.15 
associated with the contractor information system(s) used in 
performance of the contract; and
    2. an initial affirmation of compliance, and then annually 
thereafter, an affirmation of continued

[[Page 89082]]

compliance as set forth in 32 CFR 170.22.
    3. the Level 1 Self-Assessment cost burden will be addressed as 
part of the 48 CFR acquisition rule.

CMMC Level 2 Self-Assessment

    <bullet> CMMC Level 2 Self-Assessment requires compliance with the 
security requirements set forth in NIST SP 800-171 Rev 2 to protect 
CUI. CMMC Level 2 does not add any additional security requirements to 
those identified in NIST SP 800-171 Rev 2.
    <bullet> OSAs will submit the following information in SPRS prior 
to award of any prime contract or subcontract:
    1. the results of a self-assessment of the OSA's implementation of 
the NIST SP 800-171 Rev 2 requirements set forth in 32 CFR 170.16 
associated with the covered contractor information system(s) used in 
performance of the applicable contract.
    2. an initial affirmation of compliance, and, if applicable, a 
POA&M closeout affirmation, and then annually thereafter, an 
affirmation of continued compliance set forth in 32 CFR 170.22.
    3. the Level 2 Self-Assessment cost burden will be addressed as 
part of the 48 CFR acquisition rule.

CMMC Level 2 Certification Assessment

    <bullet> CMMC Level 2 Certification requires compliance with the 
security requirements set forth in in 32 CFR 170.17 to protect CUI. 
CMMC Level 2 does not add any additional security requirements to those 
identified in NIST SP 800-171 Rev 2.
    <bullet> A CMMC Level 2 Certification Assessment of the applicable 
contractor information system(s) provided by an authorized or 
accredited C3PAO is required to validate implementation of the NIST SP 
800-171 Rev 2 security requirements prior to award of any prime 
contract or subcontract and exercise of option.
    <bullet> The C3PAO will upload the CMMC Level 2 results in eMASS 
which will feed the information into SPRS.
    <bullet> OSCs will submit in SPRS an initial affirmation of 
compliance, and, if necessary, a POA&M closeout affirmation, and then 
annually thereafter, an affirmation of continued compliance as set 
forth in 32 CFR 170.22.
    The Level 2 Certification Assessment cost burdens are included in 
this part with the exception of the requirement for the OSC to upload 
the affirmation in SPRS that is included in the Title 48 acquisition 
rule and an update to DFARS collection approved under OMB Control 
Number 0750-0004, Assessing Contractor Implementation of Cybersecurity 
Requirements. Additionally, the information collection reporting 
requirements for the CMMC instantiation of eMASS are included in a 
separate ICR for this part and cover only those requirements pertaining 
to the CMMC process.

CMMC Level 3 Certification Assessment

    <bullet> CMMC Level 3 Certification Assessment requires a CMMC 
Level 2 Final Certification Assessment and compliance with the security 
requirements set forth in 32 CFR 170.18 to protect CUI. CMMC Level 3 
adds additional security requirements to those required by existing 
acquisition regulations as specified in this rule.
    <bullet> A CMMC Level 3 Certification Assessment of the applicable 
contractor information system(s) provided by the DCMA Defense 
Industrial Base Cybersecurity Assessment Center (DIBCAC) is required to 
validate implementation of the DoD-defined selected security 
requirements set forth in NIST SP 800-172. A CMMC Level 2 Final 
Certification is a prerequisite to schedule a DIBCAC assessment for 
CMMC Level 3.
    <bullet> DCMA DIBCAC will upload the CMMC Level 3 results into the 
CMMC instantiation of eMASS, which will feed the information into SPRS.
    <bullet> OSCs will submit in SPRS an initial affirmation of 
compliance, and, if necessary, a POA&M closeout affirmation, and then 
annually thereafter, an affirmation of continued compliance as set 
forth in 32 CFR 170.22.
    The Level 3 Certification Assessment cost burdens are included in 
this part with the exception of the requirement for the OSC to upload 
the affirmation in SPRS that is included in the Title 48 acquisition 
rule and an update to DFARS collection approved under OMB Control 
Number 0750-0004, Assessing Contractor Implementation of Cybersecurity 
Requirements. Additionally, the information collection reporting 
requirements for the CMMC instantiation of eMASS are included in a 
separate ICR for this part and cover only those requirements pertaining 
to the CMMC process. As described, the CMMC Program couples an 
affirmation of compliance with certification assessment requirements to 
verify OSA implementation of cybersecurity requirements, as applicable.
    The CMMC Program addresses DoD's need to protect its sensitive 
unclassified information during the acquisition and sustainment of 
products and services from the DIB. This effort is instrumental in 
ensuring cybersecurity is the foundation of future DoD acquisitions.

Policy Problems Addressed by CMMC 2.0

    Implementation of the CMMC Program is intended to solve the 
following policy problems:

Verifies the Contractor Cybersecurity Requirements

    Neither FAR clause 52.204-21 nor DFARS clause 252.204-7012 provide 
for DoD assessment of a defense contractor or subcontractor's 
implementation of the information protection requirements within those 
clauses. Defense contractors represent that they will implement the 
requirements in NIST SP 800-171 Rev 2 upon submission of their offer. 
Findings from DoD Inspector General report (DODIG-2019-105 ``Audit of 
Protection of DoD Controlled Unclassified Information on Contractor-
Owned Networks and Systems'') indicate that DoD contractors did not 
consistently implement mandated system security requirements for 
safeguarding CUI and recommended that DoD take steps to assess a 
contractor's ability to protect this information. CMMC adds new 
assessment requirements for contractor implementation of underlying 
information security requirements, to allow DoD to assess a defense 
contractor's cybersecurity posture using authorized or accredited 
C3PAOs. The contractor and subcontractor must achieve the required CMMC 
Level as a condition of contract award.

Implementation of Cybersecurity Requirements

    Under DFARS clause 252.204-7012, defense contractors and 
subcontractors must document implementation of the security 
requirements in NIST SP 800-171 Rev 2 in a system security plan and may 
use a Plan of Action Milestones to describe how and when any 
unimplemented security requirements will be met. For the CMMC Program, 
the solicitation, will specify the required CMMC level, which will be 
determined considering program criticality, information sensitivity, 
and severity of cyber threat. Although the security requirements in 
NIST SP 800-171 Rev 2 address a range of threats, additional 
requirements are needed to significantly reduce the risk posed by APTs. 
An APT is an adversary that possesses sophisticated levels of expertise 
and significant resources that allow it to create opportunities to 
achieve its objectives by using multiple attack vectors (e.g., cyber, 
physical, and

[[Page 89083]]

deception). CMMC Level 3 requires implementation of selected security 
requirements from NIST SP 800-172 to reduce the risk of APT threats.
    The CMMC Program will require prime contractors to flow the 
appropriate CMMC requirement down throughout the entire supply chain 
relevant to a particular contract. Defense contractors or 
subcontractors that handle FCI, must meet the requirements for CMMC 
Level 1. Defense contractors that handle CUI must meet the requirements 
for CMMC Level 2 or higher, depending on the sensitivity of the 
information associated with a program or technology being developed.

Scale and Depth

    Today, DoD prime contractors must include DFARS clause 252.204-7012 
in subcontracts for which performance will involve covered defense 
information, but this does not provide the Department with sufficient 
insights with respect to the cybersecurity posture of all members of a 
multi-tier supply chain for any given program or technology development 
effort. CMMC 2.0 requires prime contractors to flow down appropriate 
CMMC Level requirements, as applicable, to subcontractors throughout 
their supply chain(s).
    Given the size and scale of the DIB, the Department cannot scale 
its existing cybersecurity assessment capability to conduct on-site 
assessments of approximately 220,000 DoD contractors and subcontractors 
every three years. The Department's existing assessment capability is 
best suited for conducting targeted assessments for the relatively 
small subset of DoD contractors and subcontractors that support 
designated high-priority programs involving CUI.
    CMMC addresses the Department's scaling challenges by utilizing a 
private-sector accreditation structure. A DoD-authorized Accreditation 
Body will authorize, accredit, and provide oversight of C3PAOs which in 
turn will conduct CMMC Level 2 Certification Assessments of actual and 
prospective DoD contractors and subcontractors. Defense contractors 
will directly contract with an authorized or accredited C3PAO to obtain 
a CMMC Certification Assessment. The cost of CMMC Level 2 activities is 
driven by multiple factors, including market forces that govern 
availability of C3PAOs and the size and complexity of the enterprise or 
enclave under assessment. The Government will perform CMMC Level 3 
Certification Assessments. Government resource limitations may affect 
schedule availability.

Reduces Duplicate or Respective Assessments of Our Industry Partners

    CMMC assessment results will be posted in SPRS, DoD's authoritative 
source for supplier and product performance information. Posting CMMC 
assessment results in SPRS precludes the need to validate CMMC 
implementation on a contract-by-contract basis. This enables DoD to 
identify whether the CMMC requirements have been met for relevant 
contractor information systems, avoids duplicative assessments, and 
eliminates the need for program level assessments, all of which 
decreases costs to both DoD and industry.

CMMC 2.0 Implementation

    The DoD is implementing a phased implementation for CMMC 2.0 and 
intends to introduce CMMC requirements in solicitations over a three-
year period to provide appropriate ramp-up time. This phased 
implementation is intended to minimize the financial impacts to defense 
contractors, especially small businesses, and disruption to the 
existing DoD supply chain. After CMMC is implemented in acquisition 
regulation, DoD will include CMMC self-assessment requirements in 
solicitations when warranted by the type of information that will be 
handled by the contractor of subcontractor(s). CMMC requirements for 
Levels 1, 2, and 3 will be included in solicitations issued after the 
phase-in period when warranted by any FCI and/or CUI information 
protection requirements for the contract effort. In the intervening 
period, Government Program Managers will have discretion to include 
CMMC requirements or exclude them and rely upon existing DFARS Clause 
252.204-7012 requirements, in accordance with DoD policy. As stated in 
32 CFR 170.20(a), there is qualified standards acceptance between DCMA 
DIBCAC High Assessment and CMMC Level 2, which will result in 
staggering of the dates for new CMMC Level 2 assessments. The 
implementation period will consist of four (4) phases as set forth in 
32 CFR 170.3(e), during which time the Government will include CMMC 
requirements in certain solicitations and contracts. During the CMMC 
phase-in period, program managers and requiring activities will be 
required to include CMMC requirements in certain solicitations and 
contracts and will have discretion to include in others.
    A purpose of the phased implementation is to ensure adequate 
availability of authorized or accredited C3PAOs and assessors to meet 
the demand.

CMMC 2.0 Flow Down

    CMMC Level requirements will be flowed down to subcontractors at 
all tiers as set forth in 32 CFR 170.23; however, the specific CMMC 
Level required for a subcontractor will be based on the type of 
unclassified information and the priority of the acquisition program 
and/or technology being developed.

Key Changes Incorporated in the CMMC 2.0 Program

    In November 2021, the Department announced ``CMMC 2.0,'' which is 
an updated program structure with revised requirements. In CMMC 2.0, 
the Department has introduced several key changes that build on and 
refine the original program requirements. These include:
    <bullet> Streamlining the model from five levels to three levels.
    <bullet> Exclusively implementing National Institute of Standards 
and Technology (NIST) cybersecurity standards and guidelines.
    <bullet> Allowing all companies subject to Level 1, and a subset of 
companies subject to Level 2 to demonstrate compliance through self-
assessments.
    <bullet> Increased oversight of professional and ethical standards 
of CMMC third-party assessors.
    <bullet> Allowing Plans of Action & Milestones (POA&M) under 
limited circumstances to achieve conditional certification.
    As a result of the alignment of CMMC 2.0 to NIST guidelines, the 
Department's requirements will continue to evolve as changes are made 
to the underlying NIST SP 800-171 Rev 2 and NIST SP 800-172 
requirements.

CMMC Assessment

Assessment Criteria

    CMMC requires that defense contractors and subcontractors entrusted 
with FCI and CUI implement cybersecurity standards at progressively 
more secure levels, depending on the type and sensitivity of the 
information.

CMMC Level 1 Self-Assessment

    An annual CMMC Level 1 Self-Assessment and annual affirmation 
asserts that an OSA has implemented all the Basic Safeguarding 
requirements to protect FCI as set forth in 32 CFR 170.14(c)(2).
    An OSA can choose to perform the annual self-assessment internally 
or engage a third-party to assist with evaluating its Level 1 
compliance. Use of a third party to assist with the

[[Page 89084]]

assessment process is still considered a self-assessment and does not 
result in a CMMC certification. An OSA can be compliant with CMMC Level 
1 requirements for an entire enterprise network or for a particular 
enclave(s), depending upon where the FCI is or will be processed, 
stored, or transmitted.

CMMC Level 2 Self-Assessment

    A CMMC Level 2 Self-Assessment and triennial affirmation attests 
that an OSA has implemented all the security requirements to protect 
CUI as specified in 32 CFR 170.14(c)(3).

CMMC Level 2 Certification Assessment

    A CMMC Level 2 Certification Assessment, conducted by a C3PAO, 
verifies that an OSC is conforming to the security requirements to 
protect CUI as specified in 32 CFR 170.14(c)(3). A CMMC Level 2 
assessment must be conducted for each OSC information system that will 
be used in the execution of the contract that will process, store, or 
transmit CUI.

CMMC Level 3 Certification Assessment

    Receipt of a CMMC Level 2 Final Certification Assessment for 
information systems within the Level 3 CMMC Assessment Scope is a 
prerequisite for a CMMC Level 3 Certification Assessment. A CMMC Level 
3 Certification Assessment, conducted by DCMA Defense Industrial Base 
Cybersecurity Assessment Center (DIBCAC), verifies that an OSC has 
implemented the CMMC Level 3 security requirements to protect CUI as 
specified in 32 CFR 170.14(c)(4). A CMMC Level 3 Certification 
Assessment must be conducted for each OSC information system that will 
be used in the execution of the contract that will process, store, or 
transmit CUI.

Impact and Cost Analysis of CMMC 2.0

Summary of Impact

    Public comment feedback on CMMC 1.0 indicated that cost estimates 
were too low. CMMC 2.0 cost estimates account for that feedback with 
the following improvements:

<bullet> Allowance for outsourced IT services
<bullet> Increased total time for the contractor to prepare for the 
assessment, including limited time for learning the reporting and 
affirmation processes
<bullet> Allowance for use of consulting firms to assist with the 
assessment process
<bullet> Time for a senior level manager to review the assessment and 
affirmation before submitting the results in SPRS
<bullet> Updated government and contractor labor rates that include 
applicable burden costs

    As a result, some CMMC 2.0 costs may be higher than those included 
in CMMC 1.0.
    The CMMC 2.0 impact analysis includes estimated costs for 
implementation of CMMC 2.0 requirements across Level 1, Level 2, and 
Level 3 for the Public (small and other than small entities, including 
the CMMC Ecosystem as set forth in 32 CFR Subpart C) and the 
Government. In summary, the total estimated Public and Government costs 
associated with this rule, calculated for a 20-year horizon in 2023 
dollars at a 7 percent discount rate and a 3 percent discount rate are 
provided as follows:

    Estimating the number of CMMC assessments for unique entities per 
level per year is complicated by the fact that companies may serve as a 
prime contractor on one effort but a subcontractor on others, and may 
also enter into subcontract agreements with more than one prime 
contractor for various opportunities.
    In addition, the CMMC Program relies upon free market influences of 
supply and demand to propel implementation. Specifically, the 
Department does not control which defense contractors aspire to compete 
for which business opportunities, nor does it control access to the 
assessment services offered by C3PAOs. OSAs may elect to complete a 
self-assessment or pursue a certification assessment at any time after 
issuance of the rule, in an effort to distinguish themselves as 
competitive for efforts that require an ability to adequately protect 
CUI. For that reason, the number of CMMC assessments for unique 
entities per level per year may vary significantly from the assumptions 
used in generating the cost estimate. The estimates represent the best 
estimates at this time based on internal expertise and public feedback.
    DoD utilized historical metrics gathered for the CMMC 1.0 Program 
and subject matter expertise from Defense Pricing and Contracting (DPC) 
and DCMA DIBCAC to estimate the number of entities by type and by 
assessment level for this analysis. The following

[[Page 89085]]

table summarizes the estimated profile used in this analysis.

    DoD is planning for a phased roll-out of each assessment level 
across 7 years with the entity numbers reaching a maximum by Year 4 as 
shown in the tables. The target of Year 4 was selected based on the 
projected capacity of the CMMC Ecosystem to grow to efficiently support 
the entities in the pipeline. For modeling efficiency, a similar roll-
out is assumed regardless of entity size or assessment level. It is 
assumed that by year 7 the maximum number of entities is reached. 
Beyond year 7, the number of entities entering and exiting are expected 
to net to zero. The following tables reflect the number of new entities 
in each year and for each level.

Public Costs

Summary of Impacted Awardee Entities
    According to data available in the Electronic Data Access system 
for fiscal years (FYs) 2019, 2020, and 2021, DoD awards an average of 
1,366,262 contracts and orders per year that contain DFARS clause 
252.204-7012, to 31,338 unique awardees, of which 683,718 awards (50%) 
are made to 23,475 small entities (75%).\29\
---------------------------------------------------------------------------

    \29\ The number of unique awardees impacted each year is \1/3\ 
of the average number of annual awardees according to the Electronic 
Data Access system (31,338/3 = 10,446). This estimate does not 
address new entrants or awardees who discontinue doing business with 
DoD.
