This management advisory provides the results of the DoD Office of Inspector General’s review of the DoD’s compliance with Federal Information Security Modernization Act of 2014 (FISMA). We identified the findings during our FY 2023 review of the DoD’s compliance with FISMA, which was announced on November 14, 2022 (Project No. D2023‑D000CP‑0026.000). We conducted work on this project from November 2022 to December 2023 with integrity, objectivity, and independence, as required by the Council of the Inspectors General on Integrity and Efficiency’s Quality Standards for Federal Offices of Inspector General.
