Abstract
DHS is publishing official notification that the Transportation Security Oversight Board (TSOB) has ratified Transportation Security Administration (TSA) Security Directive 1580- 21-01A, Security Directive 1582-21-01A, and Security Directive 1580/82- 2022-01 applicable to owners and operators of critical railroad infrastructure (owner/operators). Security Directive 1580-21-01A and Security Directive 1582-21-01A amend and extend previously ratified security directives issued to critical rail entities to maintain the cybersecurity measures required by those directives. Security Directive 1580/82-2022-01 requires owner/operators to implement performance-based cybersecurity measures necessary to prevent the disruption and degradation of critical rail infrastructure.
