From the document: "Critical infrastructure provides essential functions--such as supplying water, generating energy, and producing food--that underpin American society. Disruption or destruction of the nation's critical infrastructure could have debilitating effects. CISA [Cybersecurity and Infrastructure Security Agency] is the national coordinator for infrastructure protection. The William M. (Mac) Thornberry National Defense Authorization Act for Fiscal Year 2021 includes a provision for GAO [Government Accountability Office] to report on the effectiveness of sector risk management agencies in carrying out responsibilities set forth in the act. This report addresses (1) how the act changed agencies' responsibilities, and the actions agencies have reported taking to address them; and (2) the extent to which CISA has identified and undertaken efforts to help agencies implement their responsibilities set forth in the act. GAO analyzed the act and relevant policy directives, collected written responses from all 16 sectors using a standardized information collection tool, reviewed other DHS documents, and interviewed CISA officials."
