From the Document: "The May 2021 ransomware attack against the Colonial Pipeline [hyperlink] caused widespread repercussions, including regional gasoline shortages [hyperlink] and significant lines at the pump [hyperlink]. This was not the first domestic cyberattack to disrupt physical infrastructure, but it was one of the most consequential. Before the attack, the federal government did not regulate the cybersecurity of natural gas and hazardous liquids pipelines. Following the incident, the Transportation Security Agency (TSA)--as the sector risk management agency [hyperlink] for pipelines--issued two Security Directives imposing mandatory requirements [hyperlink] on pipeline companies' cybersecurity practices. A year later, the TSA revised and updated [hyperlink] the directives. This Insight reviews these actions and discusses issues for Congress."
