The Federal Information Security Modernization Act of 2014 (FISMA) requires each agency’s Inspector General (IG) to conduct an annual independent evaluation to determine the effectiveness of the information security program (ISP) and practices of its respective agency. Our objective was to evaluate the Tennessee Valley Authority’s ISP and agency practices for ensuring compliance with FISMA and applicable standards, including guidelines issued by Office of Management and Budget and National Institute of Standards and Technology. Our audit scope was limited to answering the FY 2019 IG FISMA metrics developed as a collaborative effort by the Office of Management and Budget, Department of Homeland Security, and Council of Inspector Generals on Integrity and Efficiency in consultation with the Federal Chief Information Officer Council. The FY 2019 IG FISMA metrics recommend a majority of the functions be at a maturity level 4 (managed and measurable) or higher to be considered effective. Based on our analysis of the metrics and associated maturity levels defined with the IG FISMA metrics, we found three of the five functions fell below the targeted level 4; therefore, TVA’s ISP was not operating in an effective manner. We made eight specific recommendations to TVA management to make improvements in the ISP.
