Defense Cybersecurity: Protecting Controlled Unclassified Information Systems
The Department of Defense (DOD) has reported implementing more than 70 percent of four selected cybersecurity requirements for controlled unclassified information (CUI) systems, based on GAO’s analysis of DOD reports (including a June 2021 report to Congress) and data from DOD’s risk management tools. These selected requirements include (1) categorizing the impact of loss of confidentiality, integrity, and availability of individual systems as low, moderate, or high; (2) implementing specific controls based in part on the level of system impact; and (3) authorizing these systems to operate. As of January 2022, the extent of implementation varied for each of the four requirement areas. For example, implementation ranged from 70 to 79 percent for the cybersecurity maturity model certification program DOD established in 2020, whereas it was over 90 percent for authorization of systems to operate.
