TSA Is Taking Steps to Address Some Pipeline Security Program Weaknesses

The U.S. depends on pipelines to deliver the natural gas, oil, and other hazardous liquids that power vehicles, heat homes, and more. But cyberattacks, such as an attack on Colonial Pipeline's IT networks in May 2021, threaten pipeline security. On Tuesday, GAO's Leslie Gordon testified that TSA—which is primarily responsible for pipeline security—is making new requirements for pipeline owners to improve their cybersecurity and prevent attacks. She also testified about previous recommendations that TSA has and has not fully addressed. Cybersecurity has been on our High Risk List since 1997.
