Self-Regulatory Organizations; The Options Clearing Corporation; 
Notice of Filing of Proposed Rule Change by The Options Clearing 
Corporation Concerning Revisions to OCC Rule 213--Cybersecurity 
Obligations

October 20, 2026.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(``Exchange Act'' or ``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice 
is hereby given that on October 8, 2026, The Options Clearing 
Corporation (``OCC'' or ``Corporation'') filed with the Securities and 
Exchange Commission (``Commission'') the proposed rule change as 
described in Items I, II, and III below, which Items have been prepared 
primarily by OCC. The Commission is publishing this notice to solicit 
comments on the proposed rule change from interested persons.

I. Clearing Agency's Statement of the Terms of Substance of the 
Proposed Rule Change

    This proposed rule change would amend OCC Rule 213--Cybersecurity 
Obligations (``Rule 213'') to further enhance OCC's security protocols 
and promote resiliency in OCC's approach to assessing and managing 
cybersecurity risks. OCC's proposed changes to Rule 213 would, among 
other things, (i) establish the concept of a ``Major Clearing Member 
System Event,'' in which OCC would be authorized to take certain 
action, including disconnection of a Clearing Member, or its Third-
Party Service Provider, connected to OCC's Systems (as defined below); 
(ii) enhance the requirements of a Clearing Member to notify OCC in the 
event of a Security Incident (which would be redefined as a ``Clearing 
Member System Event''); (iii) remove language that invites a Clearing 
Member to assess potential impact of a Clearing Member System Event on 
OCC's Systems and clarify OCC's authority to assess such incident and 
determine impact; (iv) provide OCC with the authority to inform, or 
require the Clearing Member to inform, the Clearing Member's Third-
Party Service Provider (as defined below) of the Clearing Member System 
Event; (v) update and add defined terms used throughout Rule 213; and 
(vi) incorporate other reporting, testing and approval requirements, 
process, obligations, and governance necessary for reconnection.
    The proposed changes to OCC Rule 213 are contained in Exhibit 5 to 
File No. SR-OCC-2026-010. Material proposed to be added is marked by 
underlining and material proposed to be deleted is marked with 
strikethrough text. All terms with initial capitalization that are not 
otherwise defined herein have the same meaning as set forth in the OCC 
By-Laws and Rules.\3\

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

II. Clearing Agency's Statement of the Purpose of, and Statutory Basis 
for, the Proposed Rule Change

    In its filing with the Commission, OCC included statements 
concerning the purpose of and basis for the proposed rule change and 
discussed any comments it received on the proposed rule change. The 
text of these statements may be examined at the places specified in 
Item IV below. OCC has prepared summaries, set forth in sections (A), 
(B), and (C) below, of the most significant aspects of these 
statements.

(A) Clearing Agency's Statement of the Purpose of, and Statutory Basis 
for, the Proposed Rule Change

Background
    OCC is the sole clearing agency for standardized equity options 
listed on national securities exchanges registered with the Commission. 
OCC provides clearing services for options on equities, indices, 
Exchange Traded Funds (``ETFs''), for certain transactions in futures 
and options on futures, and for certain stock loan transactions. 
Organizations become OCC Clearing Members to facilitate the clearing 
and settlement of their customer transactions or proprietary 
transactions through OCC. More specifically, in its role as a clearing 
agency, OCC guarantees the performance of its Clearing Members for all 
transactions cleared by OCC by becoming the buyer to every seller and 
the seller to every buyer (or the lender to every borrower and the 
borrower to every lender, in the case of stock loan transactions). In 
2012, OCC was designated as a systemically important financial market 
utility (``SIFMU'') by the Financial Stability Oversight Council 
pursuant to Title VIII of the Dodd-Frank Wall Street Reform and 
Consumer Protection Act of 2010 (``Dodd-Frank Act'').\4\ Such 
designation highlights the critical role that OCC plays in ensuring the 
stability and integrity of the financial markets.
---------------------------------------------------------------------------

    \4\ Financial Stability Oversight Council 2012 Annual Report, 
Appendix A: Designation of Systemically Important Financial Market 
Utilities, at 145 (2012), <a href="https://home.treasury.gov/system/files/261/2012-Appendix-A-Designation-of-Systemically-Important-Market-Utilities.pdf">https://home.treasury.gov/system/files/261/2012-Appendix-A-Designation-of-Systemically-Important-Market-Utilities.pdf</a>.
---------------------------------------------------------------------------

    Based on OCC's interconnections with its Clearing Members and with 
its Clearing Member's Third-Party Service Provider connected to OCC's 
Systems, OCC is exposed to various cybersecurity risks. Such 
cybersecurity risks have the potential to impact OCC, as well as market 
participants, as a cybersecurity attack on OCC may lead to the loss of 
data or system integrity, unauthorized disclosure of sensitive 
information, or an inability to conduct essential clearance and 
settlement functions. Moreover, as a SIFMU, a failure or disruption to 
OCC could threaten the stability of the financial system in the United 
States. Therefore, OCC believes it is prudent to enhance the 
cybersecurity notification obligations of its Clearing Members and 
strengthen OCC's ability to protect against and respond to such events 
to safeguard OCC's Systems and information against cyberattacks.

[[Page 66880]]

    In November 2023, OCC received approval \5\ from the Commission to 
amend certain provisions in OCC's Rules relating to a Clearing Member's 
obligation to address a ``Security Incident'' (currently defined as the 
occurrence of a cyber-related disruption or intrusion of a Clearing 
Member's systems that is reasonably likely to pose an imminent risk or 
threat to OCC's operations). The amended provisions became OCC's 
existing Rule 213, which established, among other things: (i) 
notification requirements of a Clearing Member in the event of a 
Security Incident and (ii) OCC's security requirements for the 
reconnection process of a Clearing Member following a Security Incident 
that results in a Clearing Member's disconnection.
---------------------------------------------------------------------------

    \5\ See Securities Exchange Act Release No. 98979 (Nov. 17, 
2023), 88 FR 82441 (Nov. 24, 2023) (SR-OCC-2023-003).
---------------------------------------------------------------------------

    In recent years, OCC has received Rule 213 notifications, however, 
none have impacted OCC. OCC monitors the threat landscape on an ongoing 
basis, maintaining a dedicated threat intelligence team responsible for 
monitoring the activities of threat actors targeting the financial 
services industry. Through this monitoring, OCC has observed an 
increase in the frequency and elevated risk of cyber events targeting 
the industry and the broader marketplace. Considering OCC's experience 
receiving Rule 213 notifications, together with the increasing 
frequency and elevated risk of cyber events in the financial services 
industry at large, OCC has identified opportunities for additional 
enhancements to Rule 213. Though no specific triggering event 
necessitated these enhancements, OCC's actions are proactive, taken in 
light of the elevated risk environment across the industry.
1. Purpose
    OCC's proposed amendments to Rule 213 are intended to further 
promote resiliency, strengthen OCC's cybersecurity protocols, and 
maintain consistency with industry standards, including by aligning 
OCC's Rules with recent rule amendments \6\ of similarly situated self-
regulatory organizations (``SROs'') with overlapping membership with 
OCC. Among other things, OCC's proposed enhancements to Rule 213 would:
---------------------------------------------------------------------------

    \6\ See Securities Exchange Act Release No.104183 (Nov. 17, 
2025), 90 FR 52453 (Nov. 20, 2025) (SR-DTC-2025-003), (SR-FICC-2025-
006), (SR-NSCC-2025-003).
---------------------------------------------------------------------------

    <bullet> Add a defined terms section to Rule 213, including 
defining OCC's ``Systems'' to include not only direct connections, but 
also established communication channels (e.g., access to File Transfer 
Protocols (``FTPs'') for transmitting data or instructions that may be 
compromised by a systems intrusion to a Clearing Member's back-office 
systems);
    <bullet> Require the Cybersecurity Confirmation to be signed by a 
senior executive of the Clearing Member or applicant who is authorized 
to attest to such matters;
    <bullet> Remove language that invites a Clearing Member to assess 
the potential impact of a Clearing Member System Event on OCC's Systems 
and operations when determining whether such incident is reportable, 
specify the timeframe in which OCC requires a Clearing Member System 
Event to be reported, and identify the specific information a Clearing 
Member must include in such notice;
    <bullet> Establish the concept of a ``Major Clearing Member System 
Event,'' including a declaration requiring the approval of two or more 
Designated Officers and prompt notification to the Chairman of the 
Board of Directors;
    <bullet> Reorganize and clarify OCC's authority to take action in 
response to a Clearing Member System Event, including specifying the 
actions that constitute a ``disconnect,'' and clarify a Clearing 
Member's related cooperation obligations;
    <bullet> Add provisions incorporating the reporting, testing, and 
approval requirements, process, obligations, and governance necessary 
for reconnection, including the ability for OCC to require an audit 
report from a Third-Party Cybersecurity Firm; and
    <bullet> Provide OCC with the authority to inform, or require the 
Clearing Member to inform, the Clearing Member's Third-Party Service 
Provider of the Clearing Member System Event if OCC determines, in its 
discretion, that such action is necessary for the protection of OCC and 
other Clearing Members.
    As described in more detail below, OCC believes its proposed 
changes will strengthen OCC's security protocols by enhancing Rule 213 
to be more efficient, effective and clear in its cybersecurity 
obligations of Clearing Members so that OCC may better address 
cybersecurity risks to protect OCC and its Clearing Members. 
Furthermore, OCC believes its proposed changes will enable OCC's 
Clearing Members to better understand and prepare for their obligations 
to OCC as it relates to a cybersecurity event.
Proposed Changes
Proposed Rule 213(a) \7\--Defined Terms
---------------------------------------------------------------------------

    \7\ Existing Rule 213(a) would be renumbered to Rule 213(b).
---------------------------------------------------------------------------

    First, OCC proposes to introduce new section (a) titled ``Defined 
Terms.'' To strengthen the provisions of proposed Rule 213 and further 
clarify OCC's requirements related to the cybersecurity obligations of 
a Clearing Member, OCC proposes to define several terms specifically 
for the purposes of Rule 213.\8\ OCC's proposed changes would:
---------------------------------------------------------------------------

    \8\ OCC's proposed amendments to Rule 213 align with the rule 
amendments of similarly situated SROs with overlapping membership 
with OCC, including the National Securities Clearing Corporation 
(``NSCC''). See supra note 6.
---------------------------------------------------------------------------

    <bullet> Define ``Best Practices'' to mean policies, procedures, 
practices or similar standards and guidelines that are reasonably 
designed and consistent with then current financial-sector 
cybersecurity standards issued by an authoritative body that is a U.S. 
governmental entity or agency, an association of a U.S. governmental 
entity or agency, or a widely recognized industry organization. The 
purpose of defining ``Best Practices'' is to clarify the standards that 
OCC would require a Third-Party Cybersecurity Firm to employ when such 
firm is engaged, as would be required by OCC Rule 213 as discussed 
further below. OCC's proposed definition of ``Best Practices'' aligns 
with Section 1001(a)(4) of the Commission's Regulation Systems 
Compliance and Integrity (``Reg SCI'').\9\
---------------------------------------------------------------------------

    \9\ 17 CFR 242.1001(a)(4).
---------------------------------------------------------------------------

    <bullet> Delete OCC's existing definition of a ``Security 
Incident'' and replace it with ``Clearing Member System Event.'' OCC 
proposes to define a ``Clearing Member System Event'' to mean an 
incident resulting from the unintended or unauthorized access to, or 
the malfunction or corruption (whether partial or total) of one or more 
systems, of a Clearing Member or its Third-Party Service Provider, 
connected to OCC's Systems. The purpose of re-defining the concept of a 
``Security Incident'' to a ``Clearing Member System Event'' is to 
capture only those disruptions to systems connected to OCC's Systems, 
whether via an established communication channel from a Clearing 
Member, or through the Clearing Member's Third-Party Service Provider; 
it is not intended to capture every disruption to every system of the 
Clearing Member or its Third-Party Service Provider. In addition, as 
described in further detail in section (d) of proposed Rule 213, OCC 
proposes to eliminate the existing definition of a

[[Page 66881]]

``Security Incident'' to remove language that invites Clearing Members 
to assess the potential impact of such incident on OCC's Systems and 
operations when determining whether an incident is reportable. OCC's 
existing definition of a ``Security Incident,'' is defined, in part, as 
an incident, or an incident that is occurring, involving a cyber-
related disruption or intrusion of the Clearing Member's systems that 
is reasonably likely to pose an imminent risk or threat to OCC's 
operations. OCC believes the language in the existing definition 
invites Clearing Members to assess whether such incident to their 
systems would impact OCC, and therefore OCC proposes to eliminate the 
definition of ``Security Incident'' and replace the definition with 
``Clearing Member System Event'' in proposed Rule 213.
    <bullet> Define ``OCC's Systems'' to mean the systems, equipment 
and technology networks of OCC, whether owned, leased, or licensed, and 
including software, hardware, applications, devices, IP addresses, or 
other addresses or accounts used in an established communication 
channel with such systems, equipment and technology networks, to 
provide the services set forth in these Rules, or otherwise used to 
transact business or connect with OCC. OCC proposes to introduce the 
definition of ``OCC's Systems'' for the purposes of Rule 213 to 
articulate OCC's potentially impacted connections and any means of 
connectivity in the event of a Clearing Member System Event. OCC's 
proposed definition incorporates not only direct connections but also 
references ``established communication channels,'' which OCC believes 
may include access to File Transfer Protocol (``FTPs'') for 
transmitting data or instructions that may be compromised by a systems 
intrusion to a Clearing Member's back-office systems.
    <bullet> Define a ``Major Clearing Member System Event'' to mean a 
Clearing Member System Event that has or is reasonably anticipated to, 
for example, disrupt, degrade, cause a delay in, interrupt or otherwise 
alter the normal operation of OCC's Systems; result in unauthorized 
access to OCC's Systems; result in the loss of control of, disclosure 
of, or loss of OCC's Confidential Information; or cause a strain on, 
loss of, or overall threat to the OCC's resources, functions, security 
or operations. The purpose of establishing the concept of a ``Major 
Clearing Member System Event,'' is to tie the disruption at issue to 
its effect on the normal operations of OCC. This concept introduces a 
threshold level in which OCC would be authorized to take action, 
including disconnection, in the event OCC determines that a Clearing 
Member System Event rises to the level of a Major Clearing Member 
System Event.\10\ OCC believes the concept of a ``Major Clearing Member 
System Event'' will strengthen OCC's security protocols by establishing 
a baseline by which OCC can measure the disruption at issue against its 
impact on OCC and, as described in further detail below, take action to 
mitigate risks presented.
---------------------------------------------------------------------------

    \10\ OCC's Information Security Disconnect and Reconnect 
Procedure is contained in Confidential Exhibit 3 of SR-OCC-2026-010, 
and it outlines how OCC determines that a Clearing Member System 
Event rises to the level of a Major Clearing Member System Event.
---------------------------------------------------------------------------

    <bullet> Define ``Third-Party Cybersecurity Firm'' to mean a firm 
that, in OCC's reasonable judgement, (A) (i) is well-known and 
reputable; (ii) is not the subject Clearing Member, or an affiliate or 
a Third-Party Service Provider of the subject Clearing Member; (iii) is 
experienced in financial-sector cybersecurity; and (iv) employs Best 
Practices; or (B) is otherwise determined to be a Third-Party 
Cybersecurity Firm by OCC. OCC proposes to include this definition to 
clearly describe the type of firm that OCC would require the subject 
Clearing Member to engage under proposed Rule 213(g)(3).
    <bullet> Define ``Third-Party Service Provider'' to mean an 
affiliate of any Clearing Member, service bureau or other similar 
entity, that connects to OCC's Systems on behalf of or for the benefit 
of a Clearing Member. This proposed definition would help clarify that 
OCC Rule 213 applies to a Clearing Member's Third-Party Service 
Provider's connections to OCC's Systems.
Proposed Rule 213(b)--Cybersecurity Confirmation Submission
    Proposed Rule 213(b) incorporates the provision from existing Rule 
213(a)(ii) into proposed Rule 213(b)(1) to promote clarification and 
efficiency. Proposed Rule 213(b) also makes other conforming and non-
substantive changes, including reorganizing provisions into a 
hierarchical structure, and updating language to promote clarity and 
efficiency.
    Existing Rule 213(a) requires Clearing Members and clearing 
membership applicants to periodically submit a form, provided by OCC, 
confirming, in part, that they have a cybersecurity program in place 
(``Cybersecurity Confirmation''). Sections (i) and (ii) of existing 
Rule 213(a) require that applicants must submit it with their 
application, and existing Clearing Members must resubmit it at least 
every two years, within 180 days of the OCC's notice requiring 
attestation. OCC's proposed changes streamline existing Rule 213(a) 
into proposed Rule 213(b)(1) by combining the general description of 
the Cybersecurity Confirmation requirement with the specific timing 
obligation applicable to Clearing Members into a single paragraph. 
Specifically, OCC's proposed Rule 213(b)(1) would provide, in part, 
that each Clearing Member must complete and submit ``an attestation at 
least every two years, and not later than 180 calendar days from the 
date that OCC notifies the Clearing Member that the attestation is 
required.'' In addition, proposed Rule 213(b)(1) would remove the 
reference to the phrase ``applicant for clearing membership'' as OCC 
believes such language is duplicative since it is included in the 
subsequent provision in proposed Rule 213(b)(2). OCC's proposed changes 
replace the term ``shall'' with ``must'' in proposed Rule 213(b)(1) and 
proposed Rule 213(b)(2) to promote stronger cadence and readability. 
OCC's proposed changes also eliminate the specific reference to the 
word ``form'' after ``attestation.'' The concept of a ``form'' and an 
``attestation'' may introduce different meanings, so this proposed 
change is intended to eliminate ambiguity and maintain consistency with 
OCC's referenced term, ``Cybersecurity Confirmation.'' OCC also 
proposes to eliminate the reference that the attestation is ``provided 
by the Corporation'' because OCC believes this is unnecessary to 
specify. Finally, OCC proposes to remove the word ``materials'' in 
proposed Rule 213(b)(2) to promote efficiency.
Proposed Rule 213(c) \11\--Representations in the Cybersecurity 
Confirmation
    OCC's proposed changes relocate the signature requirement set forth 
in existing Rule 213(c), ``Execution of the Cybersecurity 
Confirmation,'' into the introductory provision of proposed Rule 
213(c), ``Representations in the Cybersecurity Confirmation'' 
(redesignated from existing Rule 213(b)). As relocated, the requirement 
would provide that the Cybersecurity Confirmation must be signed by a 
senior executive of the Clearing Member or applicant who is authorized 
to attest to these matters, consistent with the substance of the 
existing requirement. Existing Rule 213(c) would be deleted in its 
entirety, as its sole requirement is preserved within proposed Rule 
213(c). OCC believes this change is non-

[[Page 66882]]

substantive and is designed to eliminate duplicative rule text and 
improve the clarity and organization of Rule 213. OCC's proposed 
changes also remove the word ``designated'' from the signature 
requirement, such that the Cybersecurity Confirmation may be signed by 
any senior executive of the Clearing Member or applicant who is 
authorized to attest to these matters, rather than requiring a 
designated senior executive. Specifically, proposed Rule 213(c) would 
provide that the Cybersecurity Confirmation ``must be signed by a 
senior executive of the Clearing Member or applicant who is authorized 
to attest to these matters.'' OCC believes the term ``designated'' 
creates ambiguity. Additionally, OCC believes that removing this term 
improves operational flexibility by allowing any senior executive with 
the requisite authorization to sign and improves timely compliance by 
avoiding delays that could arise if a specifically designated 
individual is unavailable at the time attestation is required. OCC 
believes the proposed change preserves the integrity and reliability of 
the attestation, since the signatory must still be a senior executive 
with the requisite authorization to attest to these matters.
---------------------------------------------------------------------------

    \11\ Existing Rule 213(b) would be renumbered to proposed Rule 
213(c).
---------------------------------------------------------------------------

    OCC's proposed changes to Rule 213(c) also make other non-
substantive changes, including reorganizing the provisions into a 
hierarchical structure and replacing the term ``shall'' with ``must'' 
to promote stronger cadence and readability.
Proposed Rule 213(d)--Occurrence of a Clearing Member System Event
    OCC's proposed Rule 213(d) would introduce enhanced notification 
requirements for a Clearing Member in the event of a Clearing Member 
System Event. More specifically, OCC's proposed changes would introduce 
a particular timeframe required for Clearing Members to report such 
incident and specify the information that must be included in the 
notification.
    First, as referenced above in the proposed ``Defined Terms'' 
section, OCC proposes to re-define and broaden the definition of 
``Security Incident'' to ``Clearing Member System Event.'' In alignment 
with this proposed change, OCC would also eliminate the existing 
definition of a ``Security Incident'' in proposed Rule 213(d), which 
states in part, that such incident is one that is occurring involving a 
cyber related disruption or intrusion of the Clearing Member's systems 
that is reasonably likely to pose an imminent risk or threat to OCC's 
operations.
    Second, OCC's proposed changes would require that a Clearing Member 
experiencing a Clearing Member System Event must notify OCC immediately 
``in writing, but no later than two hours'' after the Clearing Member 
becomes aware or should be aware that there has been a Clearing Member 
System Event. The purpose of including a specific timeframe of two 
hours for which a Clearing Member System Event must be reported is to 
clarify OCC's existing standard of ``immediate'' in order to help 
mitigate the risk presented by a Clearing Member or its Third-Party 
Service Provider that is experiencing such incident.\12\ OCC believes 
that the term ``immediately,'' standing alone, may be interpreted 
differently and therefore could create uncertainty and inconsistent 
compliance. By pairing ``immediately'' with a definite, objective two-
hour limit, OCC's Clearing Members will have a clear, unambiguous 
benchmark for timely notification. By receiving notification of a 
Clearing Member System Event within two hours of its occurrence, OCC 
believes it will be able to address and respond to such event in a 
timely manner and take proactive steps to reduce any future risk 
presented to OCC and its Clearing Members. If a Clearing Member does 
not report a Clearing Member System Event within the notification 
timeframe set forth in section (d), OCC will evaluate the facts and 
circumstances of the delay in notification to determine whether a rule 
violation has occurred that is subject to OCC's disciplinary process 
under Chapter XII of OCC's Rules.
---------------------------------------------------------------------------

    \12\ OCC's current rule 213(d) requires a member to immediately 
notify OCC and to confirm such notice promptly in writing.
---------------------------------------------------------------------------

    Third, OCC's proposed changes require that notification of proposed 
section 213(d) must, at a minimum include the following information (as 
described below), and any such information unconfirmed or otherwise 
unknown may be identified by the Clearing Member as ``Unknown.'' OCC's 
existing Rule 213 does not expressly set out requirements for what to 
include in a notification of a Clearing Member System Event. While OCC 
already obtains the required information outlined out in proposed Rule 
213(d) through its existing practice, the required information is not 
memorialized in OCC's Rules, policies, or procedures. This practice has 
historically included, among other things, requests regarding the legal 
entity name of the Clearing Member, contact information of individuals 
authorized to act on its behalf, and key details of the incident such 
as its nature, status, systems or data affected, and remediation steps 
taken. OCC typically obtains this information from the Clearing Member 
via phone or email, depending on the circumstances. This information is 
generally gathered over the course of OCC's engagement with the 
Clearing Member as the incident develops and the Clearing Member's own 
understanding of the incident evolves, rather than all at once at the 
onset of the incident. As such, the purpose of proposed section 213(d) 
is to codify what OCC already expects in practice, so that all Clearing 
Members are aware, in advance, of the information required to be 
included when reporting a Rule 213 incident.
    OCC's proposed changes provide that the information required to be 
in the notice, if known, include: (i) the legal entity name of the 
Clearing Member or its Third-Party Service Provider affected by the 
Clearing Member System Event, (ii) contact information of individuals 
who are authorized to act on behalf of the subject Clearing Member 
regarding the Clearing Member System Event, and (iii) key details of 
the Clearing Member System Event such as event type, event effect, 
start date, end date, discovery date, scope, and any other notices 
given that would help to provide additional context of the Clearing 
Member System Event. As discussed above, OCC's existing Rule 213 does 
not expressly set out requirements for what information must be 
included in a notification of a Clearing Member System Event. In 
practice, OCC would obtain the same details identified in proposed 
section 213(d), but not all at once and not in the formal manner that 
proposed section 213(d) establishes.
    OCC's proposed changes to Rule 213(d) would provide that the 
information required in the notice related to ``Legal Entities'' would 
include a complete list of the legal entity names of the Clearing 
Member and any Third-Party Service Providers experiencing or otherwise 
affected or potentially affected by the Clearing Member System Event. 
In addition, OCC's proposed changes would require that information 
required in the notice related to ``Contact Information'' would include 
list of persons--with their corresponding titles, primary email 
addresses and phone numbers, and if those primary email addresses and 
phone numbers are associated with the systems that are the subject of 
the Clearing Member System Event, alternate email addresses and phone 
numbers--who are authorized to act on behalf of the subject Clearing 
Member regarding the Clearing Member System

[[Page 66883]]

Event. Furthermore, OCC's proposed changes would provide that 
information required in the notice related to ``Clearing Member System 
Event Details'' would include requirements in sections (A) through (G) 
of proposed Rule 213(d):
    (A) Event Type--the type of Clearing Member System Event, for 
example an insider threat, phishing attack, Man-in-the-Middle 
(``MITM'') \13\ attack, privilege escalation, denial of service, 
external threat, malware, unauthorized access, ransomware, compromised 
user account, SQL injections, brute force attack, system compromise, 
supply chain attacks (as each term is commonly understood by 
cybersecurity professionals in the financial sector), or other with a 
provided explanation;
---------------------------------------------------------------------------

    \13\ A man-in-the-middle (``MITM'') attack is an attack in which 
an adversary positions itself between two communicating parties in 
order to intercept and alter the data traveling between them. See 
National Institute of Standards and Technology, Computer Security 
Resource Center, Glossary, Man-in-the-Middle Attack (MitM), <a href="https://csrc.nist.gov/glossary/term/man_in_the_middle_attack">https://csrc.nist.gov/glossary/term/man_in_the_middle_attack</a>.
---------------------------------------------------------------------------

    (B) Event Effect--perceived, anticipated, or known effect of the 
Clearing Member System Event, for example, loss of communication, data 
corruption, security breach, or other with a provided explanation;
    (C) Start Date--date and time when the Clearing Member System Event 
began;
    (D) End Date--date and time when the Clearing Member System Event 
ended, if applicable;
    (E) Discovery Date--date and time when the Clearing Member System 
Event was first identified;
    (F) Scope--scope of the Clearing Member System Event, including, 
but not limited to, a list of each affected or likely affected system 
or data, including OCC's Systems and data, the degree of such affect, 
and any supporting evidence of such; and
    (G) Notices--whether any formal or informal notices or information 
regarding the Clearing Member System Event was made public and, if so, 
provide a copy of such notices or information.
    The purpose of these proposed changes is to codify OCC's 
expectations to increase transparency around OCC's existing process. 
More specifically, OCC's proposed changes codify, within Rule 213(d), 
the information that OCC has historically requested from Clearing 
Members during a Rule 213 event. Currently, OCC receives this 
information from Clearing Members upon request during a Rule 213 event 
as an incident unfolds, rather than receiving a standardized set of 
information upfront. By codifying OCC's expectations directly in this 
Rule, OCC intends to increase transparency and ensure that all Clearing 
Members know, in advance, precisely what information they must provide 
when reporting a Rule 213 incident, as well as the types of information 
OCC may request as its investigation proceeds. OCC believes this 
advance clarity will enable Clearing Members to prepare more 
effectively and will allow OCC to more promptly and effectively review 
and mitigate any risk associated with the incident.
    OCC believes that the requested information in the proposed 
sections (A) through (G), including Legal Entities, Contact 
Information, and details of the Clearing Member System Event are 
essential pieces of information that would help OCC to efficiently and 
effectively review and take action to mitigate risk presented. OCC also 
believes the proposed changes will allow Clearing Members and their 
Third-Party Service Providers to better understand and prepare for 
their obligations to OCC in the event they experience a Clearing Member 
System Event.
Proposed Rule 213(e) \14\--Declaration of a Major Clearing Member 
System Event
---------------------------------------------------------------------------

    \14\ Existing Rule 213(e) would be renumbered to Rule 213(g).
---------------------------------------------------------------------------

    OCC proposes to introduce new Rule 213(e) sections (1) through (3), 
which would focus on the declaration of a Major Clearing Member System 
Event, including the details surrounding who is authorized to declare 
such event and notification requirements associated with such event.
    First, proposed Rule 213(e)(1) would provide that upon becoming 
aware of a Clearing Member System Event, OCC will consider whether such 
Clearing Member System Event meets the definition of a Major Clearing 
Member System Event. The proposed change would also provide that the 
existence of a Major Clearing Member System Event must be declared by 
two or more Designated Officers of OCC, in their reasonable judgement.
    Second, proposed Rule 213(e)(2) would provide that upon declaration 
of a Major Clearing Member System Event, OCC may act (or refrain from 
acting) pursuant to this Rule to help address, correct, mitigate or 
alleviate any and all risks presented to OCC by or related to the Major 
Clearing Member System Event. The proposed change would also provide 
that action taken will be in consideration of the risks presented to 
OCC, including but not limited to, information provided pursuant to 
this Rule.
    The purpose of OCC's Proposed Rule 213(e)(1) through (2) is to 
clarify that OCC will assess the potential impact of a Clearing Member 
System Event on OCC's Systems and operations, and OCC will determine to 
act, or refrain from acting, depending on the details of the Clearing 
Member System Event. The proposed rule removes any ambiguity that may 
exist in present language that invites the Clearing Member to assess 
potential impact of the Clearing Member System Event on OCC's Systems 
or operations. The purpose of the proposed change is also to clearly 
define who is authorized to declare a Major Clearing Member System 
event, specifically, that such a declaration must be made by two or 
more Designated Officers of OCC. OCC believes it is appropriate that 
such declaration be made by two or more Designated Officers of OCC to 
ensure that information regarding the Clearing Member System Event has 
been escalated to and considered at the highest management level. OCC 
believes the proposed rule change also provides transparency to 
Clearing Members and other stakeholders as to who is authorized to 
declare a Major Clearing Member System Event.
    Lastly, OCC's proposed changes introduce a new requirement that OCC 
notify the Chairman of the Board of Directors following a declaration 
of a Major Clearing Member System Event. Specifically, proposed Rule 
213(e)(3) provides that following declaration of a Major Clearing 
Member System Event, OCC will promptly notify the Chairman of the Board 
of Directors of such declaration. Because a Major Clearing Member 
System Event reflects OCC's determination that a Clearing Member System 
Event may have a significant impact on OCC's Systems or operations, OCC 
believes it is appropriate that this information be escalated to the 
Chairman of the Board of Directors without delay. OCC believes that 
notifying the Chairman is appropriate because it allows the Chairman to 
determine, based on the nature and severity of the specific Major 
Clearing Member System Event, the extent to which the full Board or any 
relevant Board Committee should be further notified or involved.
Proposed Rule 213(f)--Authority To Take Action and Required Cooperation
    Proposed Rule 213(f) would expand upon OCC's existing authority to 
take action in the event of a Clearing Member System Event and 
associated Major Clearing Member System Event. More specifically, 
proposed Rule 213(f)

[[Page 66884]]

introduces requirements surrounding: (i) OCC's ability to act, or 
refrain from acting, in the event of a Major Clearing Member System 
Event, (ii) OCC's responsibility to notify the Clearing Member of any 
disconnect or material action taken, and (iii) the Clearing Member's 
responsibility to cooperate fully and to the reasonable satisfaction of 
OCC in the event of a Major Clearing Member System Event. Proposed Rule 
213(f) also makes other conforming and non-substantive changes, 
including reorganizing provisions into a hierarchical structure, and 
updating language to promote clarity and efficiency.
    OCC's proposed changes would organize Rule 213(f) into subsections 
(1) through (4). Proposed Rule 213(f)(1) details, in part, OCC's 
ability to, in the event of a Clearing Member System Event, take 
actions reasonably necessary to mitigate any impact to its operations, 
including actions described in proposed Rule 213(f)(1)(A) through Rule 
213(f)(1)(C).\15\ OCC's changes to proposed Rule 213(f)(1)(A) make 
conforming and non-substantive changes to the text, including removing 
the phrase ``the right to.'' To maintain consistency and align with 
OCC's proposed definition of OCC's Systems, OCC proposes to eliminate 
the term ``data'' before systems in proposed Rule 213(f)(1)(A). 
Proposed Rule 213(f)(1)(B) is new and provides that OCC may take 
actions reasonably necessary to mitigate any effects to its operations, 
including to suspend any and all transmissions, communications, or 
access between OCC's Systems (together with actions taken under Rule 
213(f)(1)(A), ``disconnect''). The purpose of this change is to broaden 
OCC's authority to take action that OCC believes may be necessary to 
mitigate risk presented by a Clearing Member System Event and 
associated Major Clearing Member System Event. In addition to OCC's 
existing authority to disconnect access of a Clearing Member, as 
described in proposed Rule 213(f)(1)(A), OCC believes the proposed 
change to expand OCC's authority to suspend any and all transmission, 
communication or access of a Clearing Member will help to ensure that 
OCC can adequately address all potential connectivity and communication 
types of a Clearing Member. OCC also proposes to adopt new Rule 
213(f)(1)(C) to provide OCC the authority to act in the event OCC 
determines that a Major Clearing Member System Event has occurred. 
Proposed Rule 213(f)(1)(C) provides that OCC may take, or refrain from 
taking, or require the subject Clearing Member to take or refrain from 
taking, any and all action that OCC considers appropriate to help 
address, correct, mitigate or alleviate the Major Clearing Member 
System Event and, as appropriate and practical, facilitate the 
continuation of services, which may include issuing instructions to the 
subject Clearing Member and requiring such Clearing Member to act on 
such instructions. Examples of actions that OCC considers appropriate 
may include, but are not limited to, disconnection from OCC's Systems, 
forced password resets, and requiring the Clearing Member to use 
alternative communication and file transfer methods (e.g., secure file 
transport instead of email). The purpose of this proposed change is to 
provide OCC with the authority to evaluate and address a Major Clearing 
Member System Event and adequately respond to such event in effort to 
mitigate impact to OCC and its Clearing Members. Additionally, in the 
event OCC determines a Major Clearing Member System Event has occurred, 
by adding the provision that allows OCC to issue instructions and 
requires the subject Clearing Member to follow those instructions, OCC 
believes this requirement will help to help facilitate the continuation 
of services for the subject Clearing Member and alleviate future impact 
that may otherwise result from the disruption. Specifically, the 
issuance of instructions allows OCC to direct a more tailored response 
that is specific to the nature and severity of the Major Clearing 
Member System Event. This flexibility enables OCC to address the risk 
presented by a specific Major Clearing Member System Event while, where 
practicable, preserving the Clearing Member's ability to continue some 
or all of its services during remediation.
---------------------------------------------------------------------------

    \15\ The proposed changes would not substantively alter this 
section of 213(f) but include only conforming changes such as 
changes to match defined terms.
---------------------------------------------------------------------------

    OCC proposes to adopt Rule 213(f)(3), which addresses OCC's 
notification requirements to the Clearing Member, as well as the 
subject Clearing Member's obligations to comply with OCC's statutory 
rules. More specifically, proposed Rule 213(f)(3) would provide that 
OCC will promptly notify the Clearing Member of any disconnect or other 
material action that OCC takes with respect to such Clearing Member 
pursuant to Rule 213. In addition, proposed Rule 213(f)(3) would 
provide that, notwithstanding any action taken pursuant to Rule 213, 
the Clearing Member must continue to meet its obligations to OCC and 
comply with OCC's statutory rules, as defined in its By-Laws. Under 
OCC's existing Rule 213, if OCC determines that disconnection of a 
Clearing Member from OCC's Systems is necessary, the Clearing Member 
must continue to meet its obligations to OCC notwithstanding that 
disconnection. OCC's existing Rule 213(d) focuses solely on the 
Clearing Member's continuing obligations following a disconnection and 
it does not address whether OCC will notify the Clearing Member that a 
disconnection (or any other action) has occurred. Proposed Rule 
213(f)(3) expands the current provision in two respects: (i) it adds a 
notification obligation on OCC's part, and (ii) it broadens both the 
scope of triggering actions (from disconnection alone to any material 
action under the Rule) and the scope of the Clearing Member's 
continuing obligations to also include compliance with OCC's statutory 
rules, as the term is defined in OCC's By-Laws.
    These proposed changes serve several purposes. First, the purpose 
of requiring OCC to promptly notify a Clearing Member of any 
disconnection or other material action taken under this Rule is to 
provide enhanced transparency to Clearing Members regarding actions 
that OCC takes that impact them. OCC believes it is prudent to notify 
the Clearing Member promptly in such event to allow the Clearing Member 
to better prepare for and understand their obligations to OCC. Second, 
the proposed change expands the scope of that notification obligation 
from disconnection alone to ``any material action'' taken pursuant to 
the Rule. This may include, for example, modifying the scope and 
specifications of access of the Clearing Member to OCC's Systems. The 
purpose of this proposed change is to ensure that Clearing Members 
receive notice of any material action OCC may take, not solely the most 
severe action of disconnection. Third, the proposed change broadens the 
Clearing Member's continuing obligations to apply ``notwithstanding any 
action taken pursuant to this Rule,'' rather than only 
``notwithstanding disconnection,'' removing any ambiguity as to whether 
a Clearing Member's obligations to OCC continue in the event OCC takes 
a material action, outside of disconnection. Finally, the proposed 
change also specifies what obligations the Clearing Member must 
continue to meet, by adding an express requirement that the Clearing 
Member comply with the statutory rules of OCC, as defined in OCC's By-
Laws. OCC's current Rule 213 refers only generally to the Clearing 
Member's ``obligations to OCC'' without

[[Page 66885]]

specifying what those obligations include. OCC believes the addition of 
``comply with the statutory rules of OCC, as defined in its By-Laws'' 
clarifies what those obligations encompass. OCC's proposed changes to 
proposed Rule 213(f)(3) also make other conforming, non-substantive 
changes.
    Lastly, OCC proposes to adopt new Rule 213(f)(4), which requires 
that the Clearing Member must cooperate fully and completely with, and 
to the reasonable satisfaction of, OCC in all matters relating to the 
Major Clearing Member System Event, including, but not limited: (i) 
conducting timely investigations and inquiries, as OCC believes 
reasonably necessary, with respect to any known or unknown information 
relating to the Clearing Member System Event; (ii) promptly notifying 
OCC of any material changes, updates, or new information learned 
regarding the Clearing Member System Event; and (iii) promptly 
providing any documentation or information requested by OCC, unless not 
legally permitted to do so, regarding or related to the Clearing Member 
System Event.\16\ The purpose of this proposed change is to provide 
enhanced transparency to Clearing Members on their obligations to 
comply with the proposed requirements. OCC believes that cooperation 
from Clearing Members on matters relating to a Major Clearing Member 
System Event will help OCC to efficiently and effectively manage and 
respond to a Major Clearing Member System Event in effort to mitigate 
risk presented.
---------------------------------------------------------------------------

    \16\ Sections (i) through (ii) described in the narrative would 
be numbered to proposed Rule 213(f)(4)(A) though proposed Rule 
213(f)(4)(C).
---------------------------------------------------------------------------

Proposed Rule 213(g) \17\ Procedures for Reconnection
---------------------------------------------------------------------------

    \17\ Existing Rule 213(e) would be renumbered to proposed Rule 
213(g).
---------------------------------------------------------------------------

    OCC proposes to update existing Rule 213(e) titled ``Procedures for 
Connecting Following a Security Incident that Results in 
Disconnection'' to Proposed Rule 213(g) titled ``Procedures for 
Reconnection.'' OCC believes that such change in title is necessary to 
more accurately encompass the obligations of a Clearing Member pursuant 
to OCC's authority to act in the event of a Clearing Member System 
Event, as described in proposed Rule 213(f)(1). The retitled rule sets 
forth the information that the subject Clearing Member would be 
required to provide OCC in the event OCC takes action pursuant to 
proposed Rule 213(f)(1) and includes both substantive and non-
substantive changes as described below. Proposed Rule 213(g) also 
reorganizes existing Rule 213(e) into proposed Rule 213(g)(1) through 
213(g)(2), and incorporates new section (3) in proposed Rule 213(g)(3) 
titled ``Report from Third-Party Cybersecurity Firm.''
Proposed Rule 213(g)(1) Reconnection Attestation
    OCC's proposed Rule 213(g)(1) would be titled ``Reconnection 
Attestation.'' Proposed Rule 213(g)(1) would include the current 
requirement that a subject Clearing Member must complete and submit a 
Reconnection Attestation prior to OCC reestablishing connectivity to 
OCC's Systems. More specifically, proposed Rule 213(g)(1) would provide 
that if OCC takes action pursuant to Rule 213(f)(1), the Clearing 
Member must complete and submit a form as provided by OCC that 
describes the Clearing Member System Event and includes required 
representations (``Reconnection Attestation''). OCC proposes to add 
language to clarify that such requirement must be met prior to OCC 
reestablishing connectivity to OCC's Systems (``Reconnection''). OCC 
proposes to relocate the existing provision that states ``The Clearing 
Member also will be required to complete an associated checklist 
provided by OCC that describes remediation efforts (``Reconnection 
Checklist''),'' because OCC believes such text is more appropriately 
located in proposed Rule 213(g)(2), which outlines the requirements in 
the Reconnection Checklist. In addition, OCC's proposed changes 
collapse and consolidate Rule 213(e)(1) into Rule 213(e), which becomes 
proposed Rule 213(g), such that the signature requirement is now 
reflected in proposed Rule 213(g)(1). Specifically, OCC's proposed 
changes reflect that the provision in current Rule 213(e)(1) on the 
requirement for the Reconnection Attestation to be signed by a 
designated senior executive becomes included in proposed Rule 
213(g)(1). This change is intended to make Rule 213 easier to navigate 
by grouping related requirements together; it does not alter the 
Clearing Member's underlying obligation to obtain a signature from an 
individual who maintains the authorization to sign the Reconnection 
Attestation. OCC's proposed changes also eliminate the term 
``designated'' when describing the senior executive of the Clearing 
Member that must sign the Reconnection Attestation. OCC believes the 
term ``designated'' creates ambiguity. By removing this term, OCC 
believes it improves operational flexibility by allowing any senior 
executive of the Clearing Member \18\ with the requisite authorization 
to sign, and it improves timely compliance by avoiding delays that 
could arise if a specifically designated individual is unavailable at 
the time attestation is required. OCC believes the proposed change 
preserves the integrity and reliability of the attestation, since the 
signatory must still be a senior executive with the requisite 
authorization to attest to these matters.
---------------------------------------------------------------------------

    \18\ A senior executive of the Clearing Member with the 
requisite authorization to sign may for example include, but is not 
limited to, a member of the board of directors or a member of senior 
management with the requisite knowledge and experience to make such 
an attestation, as determined by the Clearing Member's own 
delegation of authority and procedures.
---------------------------------------------------------------------------

    In addition, proposed Rule 213(g)(1)(A) through 213(g)(1)(E) 
incorporates the requirements in current Rule 213(e)(1)(A) though Rule 
213(e)(1)(E) and makes other non-substantive changes including renaming 
the term ``Security Incident'' to ``Clearing Member System Event,'' as 
described in proposed Rule 213(a).
Proposed Rule 213(g)(2) Reconnection Checklist
    OCC's proposed Rule 213(g)(2) would be titled ``Reconnection 
Checklist.'' Proposed Rule 213(g)(2) reorganizes the provisions from 
existing Rule 213(e)(2) into proposed Rule 213(g)(2) and subsections 
(A) through (J) of proposed Rule 213(g)(2) to promote clarity and 
efficiency. OCC's proposed changes also make other conforming, 
clarifying and non-substantive changes. More specifically, OCC's 
proposed changes to Rule 213(g)(2) provide that if OCC takes action 
pursuant to Rule 213(f)(1), the Clearing Member must complete an 
associated checklist as provided by OCC that describes remediation 
efforts (``Reconnection Checklist''), which may require information 
including but not limited to the information in proposed subsections 
(A) though (J) of proposed Rule 213(g)(2).
Proposed Rule 213(g)(3) Report From Third-Party Cybersecurity Firm
    OCC proposes to adopt Rule 213(g)(3), titled ``Report from Third-
Party Cybersecurity Firm,'' which provides that OCC may require that 
the subject Clearing Member provide a report from a Third-Party 
Cybersecurity Firm, either as a condition to Reconnection or following 
Reconnection. OCC's proposed changes describe the information required 
to be in such report in proposed Rule 213(g)(3)(A) through proposed 
Rule 213(g)(3)(G).

[[Page 66886]]

    More specifically, proposed Rule 213(g)(3) states that if OCC takes 
action pursuant to Rule 213(f)(1), OCC may require, either as a 
condition to reconnection or following reconnection, that the Clearing 
Member provide a detailed, comprehensive, and auditable report from a 
Third-Party Cybersecurity Firm, or a summary or such report that 
includes: (i) a timeline of the Clearing Member System Event, including 
all material actions, events, and decisions taken for or relating to 
the Clearing Member System Event; (ii) a description of the Clearing 
Member System Event and an explanation of how such disruption was 
corrected or resolved; (iii) root cause analysis of the Clearing Member 
System Event; (iv) confirmation that any issues identified by the 
Third-Party Cybersecurity Firm as severe, critical, or moderate, or 
comparable categorizations, have been resolved; (v) confirmation of 
normal or intended operation of the subject system(s), including, but 
not limited to, the return or replacement of key systems and data 
stores to pre-Clearing Member System Event resilience, in a safe, 
secure and proper manner for at least 72 hours; (vi) a description of 
short-and long-term preventive monitoring and detection recommendations 
form the Third-Party Cybersecurity Firm; and (vii) any other 
information reasonably requested to be included by OCC.\19\ In the 
event a Clearing Member is the subject of action pursuant to OCC's 
authority under proposed Rule 213(f)(1), the purpose of proposed Rule 
213(g)(3) is to provide OCC with all necessary information about the 
subject Clearing Member's disruption and its remediation from an 
independent, knowledgeable and reputable Third-Party Cybersecurity 
Firm, so that OCC can determine whether Reconnection is appropriate. 
OCC's ability to require an audit report from a Third-Party 
Cybersecurity Firm provides OCC with essential information that will 
help OCC to fully evaluate the Clearing Member System Event and take 
steps to mitigate risks presented by such incident.
---------------------------------------------------------------------------

    \19\ The provisions described in subsections (i) through (vii) 
above would be organized as subsections (A) through (G), 
respectively, in proposed Rule 213(g)(3).
---------------------------------------------------------------------------

Proposed Rule 213(h) Reconnection Testing and Approval
    OCC's proposed changes would adopt Rule 213(h) titled 
``Reconnection Testing and Approval, '' which would require, prior to 
any Reconnection, that the subject Clearing Member must demonstrate, as 
applicable, to OCC's reasonable satisfaction, that it: (i) can operate 
in a test environment, including, but not limited to, sending and 
receiving messages and transactions; (ii) can replay or resubmit 
previously submitted messages or transactions; (iii) can reverse or 
void previously submitted messages or transactions; (iv) can confirm 
the integrity of messages and transactions; (v) has alternative 
communication methods with OCC to facilitate the exchange of messages, 
transactions, and reports; and (vi) can complete any other such 
requirements as are reasonably requested by OCC. Furthermore, proposed 
Rule 213(h)(2) would authorize two or more Designated Officers of OCC 
to, in their reasonable judgment, approve the Reconnection of a 
Clearing Member that was the subject of action taken pursuant to 
proposed Rule 213, after OCC has received all required information 
pursuant to this Rule, in a form and a substance satisfactory OCC, and 
that all information necessary for a safe Reconnection and certain 
testing has occurred, pursuant to proposed Rule 213(h)(1).
    The purpose of proposed Rule 213(h) is to ensure that the approval 
for a Reconnection is not made until OCC has received, to its 
satisfaction, all necessary information from the Clearing Member, and 
that OCC confirmed the subject Clearing Member can safely perform the 
capabilities necessary for submitting, receiving, and correcting 
information appropriately and in a manner unaffected by the Clearing 
Member System Event, so as to help mitigate the risk presented by the 
Reconnection. In addition, OCC believes it is appropriate that the 
approval of a Reconnection be made by at least two members of OCC's 
management committee to help ensure that information regarding the 
Reconnection has been escalated to the highest management level.
Proposed Rule 213(i) Certain Miscellaneous Matters
    OCC proposes to adopt Rule 213(i), titled ``Certain Miscellaneous 
Matters,'' which would address various provisions including, but not 
limited to, (i) OCC's limited liability to a Clearing Member pursuant 
to proposed Rule 213; (ii) OCC's authority to inform the subject 
Clearing Member's Third-Party Service Provider, or require the Clearing 
Member to inform its Third-Party Service Provider, of a Clearing Member 
System Event; and (iii) the failure of a Clearing Member to comply with 
proposed Rule 213.
    First, in an effort to promote enhanced transparency to Clearing 
Members, proposed Rule 213(i)(1) would address, in part, OCC's limited 
liability to any Clearing Member as it relates to losses arising out of 
OCC's action or inaction pursuant to proposed Rule 213. More 
specifically, proposed Rule 213(i)(1) would provide that without 
limiting any other provisions in these Rules concerning limitations on 
liability, neither OCC nor its directors, officers, employees, agents, 
or contractors shall be liable to any Clearing Member or any customer 
or client thereof for: (i) any failure, hindrance, interruption or 
delay in performance in whole or in part of the obligations of OCC 
under these Rules, if that failure, hindrance, interruption or delay 
arises out of or relates to a Clearing Member System Event, Major 
Clearing Member System Event, or any action or inaction pursuant to 
this Rule 213; or (ii) any loss, liability, damage, cost or expense 
arising from or relating in any way to any advice, request, 
requirement, instruction, action or inaction pursuant to this Rule 
213.\20\ Second, proposed Rule 213(i)(2) would provide that the power 
of OCC to take any action pursuant to this Rule 213, or to request or 
require any action, documentation, or information pursuant to this Rule 
213, also includes the power to waive, repeal, rescind, revoke, amend, 
or vary any such action, request, or requirement in consideration of 
the facts and circumstances. Third, proposed Rule 213(i)(3) would 
provide that the powers of OCC pursuant to this Rule 213 are in 
addition to, and not in limitation of, any authority granted elsewhere 
in these Rules to act as specified therein. The purpose of proposed 
Rule 213(i)(2) and proposed Rule 213(i)(3) is to promote enhanced 
transparency to Clearing Member on OCC's authority to take action 
pursuant to Rule 213 so that Clearing Members can better understand and 
be prepared for their obligations to OCC.
---------------------------------------------------------------------------

    \20\ The provisions described in (i) through (ii) would be 
organized as proposed Rule 213(i)(1)(A) through 213(i)(1)(B).
---------------------------------------------------------------------------

    Fourth, proposed Rule 213(i)(4) would provide that all information 
related to or regarding a Major Clearing Member System Event and all 
acts pursuant to this Rule 213 will be considered Confidential 
Information pursuant to these Rules; provided, however, that the OCC 
may inform, or direct the Clearing Member to inform, the Clearing 
Member's Third-Party Service Provider of a Clearing Member System Event 
if OCC determines, in its discretion, that such action is necessary for 
the protection of OCC and other Clearing Members. The purpose of the 
proposed change is to mitigate risk to

[[Page 66887]]

OCC and its Clearing Members that may be presented by a Clearing Member 
System Event and associated Major Clearing Member System Event. The 
proposed changes also provide transparency to Clearing Members on their 
obligation to inform their Third-Party Service Providers in certain 
circumstances that OCC deems necessary.
    Fifth, proposed Rule 213(i)(5) would provide that the failure of a 
Clearing Member to comply with the requirements of this Rule 213 may 
subject the Clearing Member to any and all disciplinary action 
permitted under these Rules, including, without limitation, suspension. 
Lastly, proposed Rule 213(i)(6) would provide that a Clearing Member 
that has authorized another party, such as a Third-Party Service 
Provider, to access and use OCC's systems will be responsible for such 
authorized party's compliance with the requirements of this Rule 213 
and any compliance failure by that authorized party will be deemed to 
be a failure of the authorizing Clearing Member. The purpose of 
proposed Rules 213(i)(5) and 213(i)(6) is to highlight the importance 
of complying with proposed Rule 213 and the actions OCC may take if 
there is a failure to comply.
2. Statutory Basis
    OCC believes the proposed rule change is consistent with Section 
17A of the Exchange Act \21\ and Rule 17ad-22(e)(2) and (e)(17) \22\ 
thereunder. Section 17A(b)(3)(F) of the Act \23\ requires, among other 
things, that the rules of a clearing agency be designed to promote the 
prompt and accurate clearance and settlement of securities 
transactions, and to assure the safeguarding of securities and funds 
which are in the custody or control of the clearing agency or for which 
it is responsible. OCC's proposed amendments to Rule 213 are designed 
to help OCC assess and take appropriate action to manage the 
cybersecurity risks that may be introduced to OCC's Systems and 
information due to a Clearing Member System Event. The proposed changes 
to Rule 213 enhance OCC's processes to help mitigate risk and better 
protect OCC and its Clearing Members.

    \21\ 15 U.S.C. 78q-1.
    \22\ 17 CFR 240.17ad-22(e)(2) and (e)(17).
    \23\ 15 U.S.C. 78q-1(b)(3)(F).
---------------------------------------------------------------------------

    As described above, the proposed rule change would, in part: (i) 
introduce a defined terms section to Rule 213 that broadens the 
definition of OCC Systems to include established communication 
channels, such as FTPs, in addition to direct connections; (ii) require 
that the Cybersecurity Confirmation be signed by a senior executive of 
the Clearing Member or applicant who is authorized to attest to such 
matters; (iii) remove language inviting a Clearing Member to assess the 
potential impact of a Clearing Member System Event on OCC's systems and 
operations when determining whether the event is reportable, and 
instead specify the timeframe for reporting such an event and the 
specific information that must be included in the notice; (iv) 
establish the concept of a ``Major Clearing Member System Event,'' 
including a declaration process requiring approval by two or more 
Designated Officers and prompt notification to the Chairman of the 
Board; (v) reorganize and clarify OCC's authority to take action in 
response to a Clearing Member System Event, including specifying the 
actions that constitute a ``disconnect'' and clarifying a Clearing 
Member's related obligations; (vi) add provisions establishing the 
reporting, testing, approval, and governance requirements necessary for 
reconnection, including OCC's ability to require an audit report from a 
Third-Party Cybersecurity Firm; and (vii) provide OCC with the 
authority to inform, or to require a Clearing Member to inform, the 
Clearing Member's Third-Party Service Provider of a Clearing Member 
System Event if OCC determines, in its discretion, that such action is 
necessary to protect OCC and other Clearing Members. OCC believes that 
these proposed changes will enhance Rule 213 to be more efficient, 
effective and clear in the cybersecurity obligations of its Clearing 
Members so that OCC may better address cybersecurity risks to protect 
OCC and its Clearing Members. Among the amendments discussed above, OCC 
believes the following amendments to Rule 213 are particularly 
consistent with the requirements of Section 17A(b)(3)(F) of the Act, as 
discussed in further detail below: (i) expanded notification 
requirements applicable to a Clearing Member System Event; (ii) the 
establishment of the Major Clearing Member System Event and its related 
governance; and (iii) the process for Reconnection of a Clearing 
Member.
    First, proposed Rule 213(d) codifies within OCC's rules the 
specific content and timeframe requirements for notification of a 
Clearing Member System Event, which OCC believes is consistent with the 
requirements of Section 17A(b)(3)(F) of the Act.\24\ Under proposed 
Rule 213(d), a Clearing Member would be required to provide OCC with 
specified information at the onset of a Clearing Member System Event, 
including but not limited to the event type, effect, scope, start date, 
end date, discovery date, and any public notices related to the event. 
OCC believes this requirement will allow OCC to receive consistent, 
timely information from Clearing Members, which in turn, will help to 
minimize the risk that delayed or incomplete information impacts OCC's 
ability to respond promptly and effectively to such events. As such, 
OCC believes this proposed change supports the prompt and accurate 
clearance and settlement of securities transactions and assures the 
safeguarding of securities and funds that are in the custody or control 
of OCC, consistent with Section 17A(b)(3)(F) of the Act.\25\

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

    Second, proposed Rule 213(e) establishes the concept of a ``Major 
Clearing Member System Event,'' which OCC believes is also consistent 
with the requirements of Section 17A(b)(3)(F) of the Act.\26\ Under 
proposed Rule 213(e), OCC would assess the potential impact of a 
Clearing Member System Event on OCC's Systems and operations, and would 
determine to act, or refrain from acting, depending on the specific 
details of the event. This removes the ambiguity that may exist in the 
current rule text, which instead invites the Clearing Member to assess 
potential impact of its own Clearing Member System Event on OCC's 
Systems or operations. Furthermore, under proposed Rule 213(e), the 
existence of a Major Clearing Member System Event must be declared by 
two or more Designated Officers of OCC, in their reasonable judgement. 
Following such a declaration, OCC will promptly notify the Chairman of 
the Board. OCC believes this process ensures that the most severe 
threats to OCC's Systems and operations are escalated to the highest 
levels of OCC's governance. OCC believes the establishment of a Major 
Clearing Member System Event and the governance outlined in proposed 
Rule 213(e) is consistent with Section 17A(b)(3)(F) of the Act because 
OCC, not the reporting Clearing Member, is best positioned to determine 
the severity of a threat to OCC's own Systems and operations. 
Additionally, OCC believes that escalation to the highest levels of 
OCC's governance helps to ensure events with the greatest potential 
impact to OCC receive attention and oversight proportionate to their 
severity. As such, OCC believes the proposed rule change is designed to

[[Page 66888]]

assure the safeguarding of securities and funds in the custody or 
control of OCC, consistent with the requirements in Section 
17A(b)(3)(F) of the Act.\27\
---------------------------------------------------------------------------

    \26\ Id.
    \27\ Id.
---------------------------------------------------------------------------

    Third, proposed Rule 213(h) establishes reconnection testing and 
approval requirements that OCC believes are consistent with Section 
17A(b)(3)(F) of the Act. Under proposed Rule 213(h)(1), prior to 
Reconnection, a Clearing Member must demonstrate, to OCC's reasonable 
satisfaction, that it can, in part, operate in a test environment, send 
and receive messages and transactions, replay or resubmit previously 
submitted messages or transactions, reverse or void previously 
submitted messages or transactions, confirm the integrity of messages 
and transactions, and maintain alternative communication methods with 
OCC. These requirements test the Clearing Member's operational 
capability to interact accurately and reliably with OCC's Systems, 
rather than relying on the Clearing Member's representation that it is 
prepared to reconnect. OCC believes this proposed change is designed to 
safeguard securities and funds in the custody or control of OCC by 
verifying, before Reconnection occurs, that a Clearing Member's systems 
will not transmit corrupted or otherwise unreliable messages or 
transactions into OCC's Systems and operations. As such, OCC believes 
this proposed change is designed to assure the safeguarding of 
securities and funds in the custody or control of OCC, consistent with 
the requirements in Section 17A(b)(3)(F) of the Act.\28\
---------------------------------------------------------------------------

    \28\ Id.
---------------------------------------------------------------------------

    Risks presented by a Clearing Member System Event could impact 
OCC's ability to clear and settle securities transactions, or to 
safeguard the securities and funds that are in its custody or control, 
or for which it is responsible. Therefore, by enhancing OCC's processes 
to mitigate these risks, including but not limited to: expanding the 
notification requirements, establishing the concept of a Major Clearing 
Member System Event, and enhancing its process for Reconnection, OCC 
believes the proposed changes would promote the prompt and accurate 
clearance and settlement of securities transactions and assure the 
safeguarding of securities and funds that are in the custody or control 
of the clearing agency or for which it is responsible, consistent with 
the requirements of Section 17A(b)(3)(F) of the Act.\29\
---------------------------------------------------------------------------

    \29\ Id.
---------------------------------------------------------------------------

Consistency With Rule 17ad-22(e)(2)(i) and (v)
    OCC believes the proposed changes to Rule 213 are consistent with 
Rule 17ad-22(e)(2)(i) and (v), which require, in part, that each 
covered clearing agency establish, implement, maintain and enforce 
written policies and procedures reasonably designed to provide for 
governance arrangements that (i) are clear and transparent and (ii) 
specify clear and direct lines of responsibility.\30\ OCC specifies in 
proposed Rule 213(e)(1) that the existence of a Major Clearing Member 
System Event must be declared by two or more Designated Officers of 
OCC, and OCC will provide notification of such declaration to the 
Chairman of the Board. Proposed Rule 213(e)(1) establishes a defined 
pathway from identification of the event, through declaration by two or 
more Designated Officers, to notification at the Board level. As such, 
OCC believes this specificity is consistent with the ``clear and 
transparent'' governance arrangements required by Rule 17Ad-
22(e)(2)(i). It is likewise consistent with the ``clear and direct 
lines of responsibility'' required by Rule 17Ad-22(e)(2)(v), because 
this proposed change assigns responsibility for determining a Major 
Clearing Member System Event to a specifically identified group of 
officers.
---------------------------------------------------------------------------

    \30\ 17 CFR 240.17ad-22(e)(2)(i) and (v).
---------------------------------------------------------------------------

    Similarly, with respect to Reconnection, proposed Rule 213(h)(2) 
requires that the Reconnection of a Clearing Member following OCC's 
action pursuant to proposed Rule 213(f)(1) be approved by two or more 
Designated Officers of OCC, and conditions that approval on OCC's 
receipt of all information required under Rule 213, in a form and 
substance satisfactory to OCC, and satisfaction of the applicable 
testing requirements set forth in proposed Rule 213(h)(1). By 
specifying both who is authorized to approve Reconnection and the steps 
that must be satisfied before that approval may be granted, proposed 
Rule 213(h)(2) establishes a transparent and structured approval 
process, consistent with Rule 17Ad-22(e)(2)(i). It also identifies, 
with the same specificity as the Major Clearing Member System Event 
declaration process, the officers responsible for making a 
determination to reconnect a Clearing Member, consistent with the clear 
and direct lines of responsibility required by Rule 17Ad-22(e)(2)(v). 
Therefore, OCC believes the proposed changes are consistent with Rule 
17ad-22(e)(2)(i) and (v) under the Act.\31\
---------------------------------------------------------------------------

    \31\ Id.
---------------------------------------------------------------------------

Consistency With Rule 17ad-22(e)(17)(i)
    OCC believes the proposed changes to Rule 213 are also consistent 
with Rule 17ad-22(e)(17)(i) under the Act, which requires that each 
covered clearing agency establish, implement, maintain and enforce 
written policies and procedures reasonably designed to manage the 
covered clearing agency's operational risks by identifying the 
plausible sources of operational risk, both internal and external, and 
mitigating their impact through the use of appropriate systems, 
policies, procedures, and controls.\32\
---------------------------------------------------------------------------

    \32\ 17 CFR 240.17ad-22(e)(17)(i).
---------------------------------------------------------------------------

    As described above, the proposed changes to Rule 213, in part: (i) 
enhance the requirements of Clearing Members to notify OCC in the event 
of a Clearing Member System Event; (ii) add provisions around 
reporting, testing and approval requirements, and governance necessary 
for Reconnection of a Clearing Member, in the event OCC takes action 
pursuant to proposed Rule 213(f)(1); and (iii) update and add 
definitions for purposes of Rule 213 to clarify the obligations of a 
Clearing Members and its Third-Party Service Providers.
    First, OCC believes the enhancements notification requirements in 
proposed Rule 213(d) are consistent with the requirements set forth in 
Rule 17Ad-22(e)(17)(i).\33\ Proposed Rule 213(d) outlines the 
requirements applicable to a Clearing Member's notification of a 
Clearing Member System Event to OCC. This includes removing language 
that invites a Clearing Member to assess the potential impact of the 
event on OCC's Systems and operations in determining whether the event 
was reportable, specifying the timeframe within which such an event 
must be reported, and identifying the specific information that must be 
included in the notice. OCC believes these enhancements are consistent 
with Rule 17Ad-22(e)(17)(i), which requires OCC to identify the 
plausible sources of its operational risk, both internal and external. 
Because a Clearing Member System Event represents an external source of 
potential operational risk to OCC, OCC's ability to identify and 
characterize that risk depends on receiving timely, complete, and 
accurate information from the Clearing Member. The specified content 
requirements, including but not limited to, the event type, effect, 
scope, and start, end, and discovery dates, further support OCC's

[[Page 66889]]

ability to identify the nature and extent of the risk presented. As 
such, OCC believes the proposed change helps OCC to identify, in a 
timely manner, plausible sources of operational risk presented by a 
Clearing Member System Event, and mitigate risk presented to OCC and 
its Clearing Members, consistent with Rule 17ad-22(e)(17)(i).\34\
---------------------------------------------------------------------------

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

    Second, OCC's proposed changes in Rule 213(h) enhance the 
requirements surrounding the Reconnection of a Clearing Member, which 
will help OCC evaluate and determine whether Reconnection is 
appropriate and, if so, take steps to ensure a safe Reconnection. OCC 
believes these enhancements are also consistent with the requirements 
in Rule 17Ad-22(e)(17)(i) of the Act \35\ that requires OCC to identify 
and mitigate the impact of its operational risks through appropriate 
systems, policies, procedures, and controls. Proposed Rule 213(h)(1) 
requires that, prior to Reconnection, a Clearing Member demonstrate, to 
OCC's reasonable satisfaction, that it can operate in a test 
environment, replay or resubmit previously submitted messages or 
transactions, reverse or void previously submitted messages or 
transactions, confirm the integrity of messages and transactions, and 
maintain alternative communication methods with OCC. OCC believes is 
consistent with the requirements in Rule 17Ad-22(e)(17)(i) because the 
proposed change identifies, through testing requirements, whether the 
specific risks presented by the original Clearing Member System Event, 
including, for example, data loss or communication failure, have been 
resolved. By requiring the Clearing Member to demonstrate these 
capabilities before Reconnection is granted, proposed Rule 213(h)(1) 
mitigates the risk that reconnecting the Clearing Member would 
reintroduce the same operational risk to OCC's Systems that 
necessitated the disconnection in the first place. In addition, under 
proposed Rule 213(g)(3), OCC can request a detailed, comprehensive, and 
auditable report from a Third-Party Cybersecurity Firm, either as a 
condition to or following Reconnection. This report must include, but 
is not limited to, a timeline of the Clearing Member System Event, a 
description of the event and how it was corrected or resolved, a root 
cause analysis, confirmation that any issues identified as severe, 
critical, or moderate have been resolved, confirmation that the 
affected systems have returned to normal, pre-incident operation for at 
least 72 hours, and short and long-term preventive monitoring and 
detection recommendations. OCC's ability to require an audit report 
from a Third-Party Cybersecurity Firm will enable OCC to collect and 
evaluate information from a reputable source to help OCC determine 
whether to reconnect. The requirement for an independent root cause 
analysis supports OCC's identification of the operational risk's 
underlying cause, while the requirement for verified confirmation 
supports the rule's mitigation component. As such, OCC believes this 
proposed change is consistent with the requirements in Rule 17Ad-
22(e)(17)(i).\36\
---------------------------------------------------------------------------

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

    Third, OCC believes the proposed addition of a defined terms 
section to Rule 213, including an expanded definition of OCC's Systems 
to encompass established communication channels, such as FTPs, that may 
be used to transmit data or instructions to a Clearing Member's back-
office systems, is consistent with Rule 17Ad-22(e)(17)(i) of the 
Act.\37\ OCC believes that expanding the definition of OCC's Systems to 
include these indirect channels is appropriate because a security 
intrusion can reach OCC through such a channel, in addition to a direct 
connection, so OCC believes it is prudent to codify this in its rules 
to help identify that potential source of risk. OCC's proposed changes 
also update the definition of a ``Clearing Member System Event'' to 
include an incident resulting from a Clearing Member's Third-Party 
Service Provider connected to OCC's Systems. By establishing 
definitions for these terms and, more specifically, expanding the 
definition of Clearing Member System Event to incorporate the Clearing 
Member's Third-Party Service Provider, this will help OCC to better 
identify and manage risks presented by a Clearing Member or its Third-
Party Service Provider connected to OCC's Systems.
---------------------------------------------------------------------------

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

    By enhancing reporting and notification requirements for Clearing 
Members in the event of a Clearing Member System Event, strengthening 
the testing, reporting, approval and governance requirements 
surrounding reconnection of a Clearing Member, and adding and updating 
definitions for the purpose of proposed Rule 213, OCC believes such 
changes will help to identify the plausible sources of operational 
risk, both internal and external, and mitigate their impact through the 
use of appropriate systems, policies, procedures, and controls, in 
accordance with Rule 17ad-22(e)(17)(i).\38\
---------------------------------------------------------------------------

    \38\ Id.
---------------------------------------------------------------------------

Consistency With Rule 17ad-22(e)(17)(ii)
    Rule 17ad-22(e)(17)(ii) under the Act requires that each covered 
clearing agency establish, implement, maintain and enforce written 
policies and procedures reasonably designed to manage the covered 
clearing agency's operational risks by ensuring, in part, that systems 
have a high degree of security, resiliency, and operational 
reliability.\39\ In addition to OCC's existing process that requires a 
Reconnection Attestation and Checklist to be submitted by a Clearing 
Member that has been disconnected, OCC's proposed changes to Rule 213 
add provisions to strengthen the overall process and requirements 
around Reconnection of a Clearing Member. These changes include, but 
are not limited to: (i) the requirement that the subject Clearing 
Member submit the Reconnection Attestation prior to OCC reestablishing 
connectivity; (ii) the obligation for the subject Clearing Member to 
complete specific testing requirements prior to Reconnection in order 
to demonstrate to OCC that it is operationally ready to reconnect; and 
(iii) OCC's ability to request a report from a Third-Party 
Cybersecurity Firm, either as a condition to Reconnection or following 
Reconnection. By requiring that the subject Clearing Member (i) submit 
the Reconnection Attestation prior to OCC reestablishing connectivity, 
and (ii) complete specific testing requirements prior to OCC 
reestablishing connectivity, OCC will be able to better identify and 
address potential vulnerabilities that may still exist within the 
Clearing Member's environment after a Clearing Member System Event has 
occurred, and take steps to promote resiliency prior to establishing 
Reconnection. Furthermore, by including the ability for OCC to require 
an audit report from a Third-Party Cybersecurity Firm, OCC will be 
provided with key details about the Clearing Member System Event from a 
reputable and experienced source. OCC will be able to rely upon the 
information in the report to help analyze and address the Clearing 
Member System Event in effort to further mitigate risk. This, in turn, 
helps to strengthen OCC's security protocols. OCC believes these 
proposed changes provide OCC with the necessary tools to address and 
manage OCC's operational risks by ensuring, in part, that systems have 
a high degree of

[[Page 66890]]

security, resiliency, and operational reliability, in accordance with 
Rule 17ad-22(e)(17)(ii).\40\

(B) Clearing Agency's Statement on Burden on Competition

    Section 17A(b)(3)(I) of the Act \41\ requires that the rules of a 
clearing agency not impose any burden on competition not necessary or 
appropriate in furtherance of the purposes of the Act. OCC does not 
believe that the proposed rule changes would impose any burden on 
competition not necessary or appropriate in furtherance of the purposes 
of the Act. As discussed above, OCC proposes to amend Rule 213 in 
effort to strengthen OCC's security protocols and promote resiliency 
when confronted with cybersecurity risks presented by OCC's 
interconnections with its Clearing Members. OCC believes the three of 
the proposed changes could have an impact on competition, but such 
impact is necessary and appropriate in further of the purposes of the 
Act. The three proposed changes that OCC believes could have an impact 
on competition include: (i) adding the definition of a Third-Party 
Service Provider in proposed Rule 213(a)(6) to include an affiliate of 
any Clearing Member, service bureau or similar entity that connects to 
OCC's Systems on behalf of or for the benefit of a Clearing Member; 
(ii) adopting proposed Rule 213(g)(3), which provides OCC with the 
ability to require an audit report from a Third-Party Cybersecurity 
Firm; and (iii) establishing the requirements for testing prior to 
reconnection of a Clearing Member, as described in proposed Rule 
213(h). As described below, although the three proposed changes may 
have an impact on competition, OCC believes that such impact is 
necessary and appropriate in further of the purposes of the Act.
---------------------------------------------------------------------------

    \41\ 15 U.S.C. 78q-1(b)(3)(I).
---------------------------------------------------------------------------

    Proposed Rule 213(a) establishes the definition of ``Third-Party 
Service Provider'' to include an affiliate of any Clearing Member, 
service bureau or similar entity, that connects to OCC's Systems on 
behalf of or for the benefit of a Clearing Member. Establishing the 
definition of Third-Party Service Provider for purposes of Rule 213 to 
include such entities described above could impose a burden on 
competition because such entities would now be explicitly subject to 
the requirements in Rule 213, including disconnection and Reconnection 
requirements. OCC acknowledges that being disconnected from OCC's 
Systems may impact the entity's ability to perform certain functions, 
therefore putting the entity at a competitive disadvantage. However, 
OCC believes that the proposed change would not create a significant 
burden. Based on OCC's critical role as a SIFMU, OCC has the 
responsibility to promote financial stability and protect the broader 
marketplace. Due to the close relationship and interconnectivity that 
exists between a Third-Party Service Provider and the related Clearing 
Member, OCC believes that it is critical to address risks presented by 
the Third-Party Service Provider that connects to OCC's Systems on 
behalf of or for the benefit of a Clearing Member. Although this 
proposed change may impose a burden on such entity, OCC does not 
believe this burden is significant, and as described in proposed Rule 
213(f)(1)(C), OCC would, as appropriate and practical, seek to 
facilitate the continuation of services for an entity that is subject 
to a Clearing Member System Event. Therefore, OCC believes the burden 
on competition is necessary and appropriate in furtherance of the 
purposes of the Act.
    Proposed Rule 213(g)(3) provides OCC with the ability to require 
that the Clearing Member must provide an audit report from a Third-
Party Cybersecurity Firm, either as a condition to Reconnection or 
following a Reconnection. Although this requirement may impose a burden 
on competition, OCC does not believe this burden is significant. As 
described above, given OCC's role as a SIFMU and its position in the 
marketplace, OCC believes it is prudent to enhance its management of 
Clearing Member System Events. OCC believes the ability to require, in 
certain circumstances, that the Clearing Member provide an audit report 
from a Third-Party Cybersecurity Firm will provide OCC with key details 
about the Clearing Member System Event. OCC believes this will help OCC 
analyze such incident and take necessary steps to mitigate risks 
presented. Although the Clearing Member may incur additional costs 
through the requirement to provide such audit report from a Third-Party 
Cybersecurity Firm, OCC believes this proposed change would not present 
an undue burden. OCC would also expect Clearing Members to leverage 
their existing relationships with Third-Party Cybersecurity Firms in 
effort to reduce costs of providing such audit report. OCC believes the 
proposed change is necessary to promote resiliency and enhance OCC's 
security protocols to protect OCC and Clearing Members from 
cybersecurity risks. Therefore, OCC believes the burden on competition 
presented by the proposed change is necessary and appropriate in 
furtherance of the Act.
    OCC believes proposed Rule 213(h), which establishes testing 
requirements for Clearing Members prior to reconnection, may impose a 
burden on competition on a Clearing Member because the changes create 
additional steps that the Clearing Member must complete prior to 
reconnection. OCC acknowledges that these additional steps, if not 
completed by the Clearing Member, could result in a Clearing Member 
being disconnected from OCC's System's for a longer period of time than 
the Clearing Member would have expected, which may impose a burden on 
the Clearing Member. However, OCC believes that the burden on 
competition from the proposed testing requirements is necessary to help 
ensure that Reconnection is safe and appropriate. The purpose of the 
proposed testing requirements is to strengthen OCC's security protocols 
so that OCC can identify any vulnerabilities related to a Clearing 
Member System Event prior to establishing any Reconnection. Although 
this proposed change may impose a burden on the Clearing Member, OCC 
does not believe this burden is significant. In addition, proposed Rule 
213(f)(1)(C), also provides that OCC will, as appropriate and 
practical, seek to facilitate the continuation of services of a 
disconnected Clearing Member, prior to Reconnection. Therefore, OCC 
believes the proposed change requiring testing requirements prior to 
Reconnection of a Clearing Member is necessary to help mitigate risk 
presented and ultimately protect OCC and other Clearing Members.
    For the foregoing reasons, OCC believes that the proposed rule 
change is in the public interest, would be consistent with the 
requirements of the Act applicable to clearing agencies, and would not 
impact or impose a burden on competition.
