The U.S. Department of Homeland Security’s (DHS) Transportation Security Administration (TSA) announced two new Security Directives and additional guidance for voluntary measures to strengthen cybersecurity across the transportation sector in response to the ongoing cybersecurity threat to surface transportation systems and associated infrastructure. These actions are among several steps DHS is taking to increase the cybersecurity of U.S. critical infrastructure.
TSA is increasing the cybersecurity of the transportation sector through Security Directives, appropriately tailored regulations, and voluntary engagement with key stakeholders. In developing its approach, including these new Security Directives, TSA sought input from industry stakeholders and federal partners, including the Department’s Cybersecurity and Infrastructure Security Agency (CISA), which provided expert guidance on cybersecurity threats to the transportation network and countermeasures to defend against them.
The TSA Security Directives announced today target higher-risk freight railroads, passenger rail, and rail transit, based on a determination that these requirements need to be issued immediately to protect transportation security. These Directives require owners and operators to:
- designate a cybersecurity coordinator
- report cybersecurity incidents to CISA within 24 hours
- develop and implement a cybersecurity incident response plan to reduce the risk of an operational disruption
- complete a cybersecurity vulnerability assessment to identify potential gaps or vulnerabilities in their systems.
TSA is also releasing guidance recommending that all other lower-risk surface transportation owners and operators voluntarily implement the same measures. Further, TSA recently updated its aviation security programs to require that airport and airline operators implement the first two provisions above. TSA intends to expand the requirements for the aviation sector and issue guidance to smaller operators. TSA also expects to initiate a rule-making process for certain surface transportation entities to increase their cybersecurity resiliency.
These efforts are part of a series of new steps to prioritize cybersecurity across DHS. Secretary Mayorkas first outlined his vision for the Department’s cybersecurity priorities in March, which included a series of focused 60-day sprints designed to elevate existing work, remove roadblocks to progress, and launch new initiatives and partnerships to achieve DHS’s cybersecurity mission and implement Biden-Harris Administration priorities.
