Transportation Worker Identification Credential: Actions Needed to Address Maritime Security Risks

What GAO Found TSA has taken some steps to communicate Transportation Worker Identification Credential (TWIC®) program information with stakeholders. However, TSA relies on an ad hoc communication approach rather than a documented communication plan to determine how to share information with stakeholders. This has contributed to some stakeholders reporting that they experienced declining engagement with and delays receiving key program updates from TSA. Developing and implementing a communication plan could help TSA ensure that all stakeholders receive the information necessary to effectively operate the TWIC® program and reduce security risks. The Coast Guard does not share or analyze all..

Aviation Cybersecurity: FAA and TSA Are Collaborating on Cybersecurity but Need to Address Key Shortfalls

What GAO Found The Federal Aviation Administration (FAA) and Transportation Security Administration (TSA) work together to ensure the cybersecurity of the interconnected systems operating in the National Airspace System (NAS). FAA defined the roles and responsibilities of the entities responsible for carrying out the agency’s related goals and objectives. In contrast, TSA did not. TSA defined its goals and objectives for prioritizing cybersecurity within the agency and in the transportation systems sector in its 2018 Cybersecurity Roadmap. However, the roadmap is outdated and no longer aligned with the latest Department of Homeland Security Cybersecurity Strategy. The roadmap also does not..

Environmental Liabilities: Coast Guard Should Give Congress More Information on Millions of Dollars in Potential Costs

What GAO Found As of September 2025, the Coast Guard reported about $448 million in environmental liabilities related to its shore infrastructure. This includes about $228 million for structures, like housing, presumed to be contaminated with asbestos-containing material or lead-based paint based on their age. It also includes about $220 million in cleanup projects at sites with a known or suspected release of contaminants. Several factors create uncertainty that could potentially lead to hundreds of millions of dollars of additional cleanup costs that the Coast Guard has not communicated to Congress.

Coast Guard: Actions Needed to Help Ensure Effective Use of Billions in Funding for Modernization Efforts

What GAO Found The Department of Homeland Security (DHS) and Coast Guard leadership have made a case that the service needs transformation. Since 2019 GAO has reviewed four Coast Guard reform efforts and identified steps the service took to incorporate leading practices as well as gaps in key areas. For example, in prior reviews of Coast Guard sexual misconduct and modernization of mission planning and reserve component reform efforts, GAO found that the Coast Guard did not fully assess its workforce needs. Additionally, for two of the reform efforts, the Coast Guard did not fully establish goals and outcomes, making it difficult to determine if the reforms had the intended effects. Accordi.
