Office of Security Assessments


The Office of Security Assessments is responsible for the independent evaluation of the effectiveness of safeguards and security policies and programs throughout the Department, including protection of special nuclear material, and classified and sensitive information. The Office has established and maintains a continuous program for assessing the security of DOE facilities through expert program and technical analysis, including a systematic approach to performance testing that is applied across all security disciplines. In particular, the Office maintains and manages the Composite Adversary Team to run exercises to test the capabilities of facilities storing special nuclear materials to counter threats posed by terrorists in a manner that is realistic and safe. The Office develops and validates reports that identify findings, issues, and opportunities for improvement. It also performs follow-up reviews to ensure complex-wide and site specific corrective actions are appropriately addressed.
