We plan to begin the subject audit in October 2022. We are conducting the audit at the direction of the Senate Armed Services Committee. The objective of this audit is to determine the extent to which the Department of Defense (DoD) developed guidance, conducted training, and oversaw the implementation of the DoD Controlled Unclassified Information (CUI) Program. We will also review a sample of CUI documents from selected DoD Components and contractors to determine whether the documents are properly marked. We may revise the objective as the audit proceeds, and we will also consider suggestions from management on additional or revised objectives.
