Where should DoD employees look for guidance on safeguarding Controlled Unclassified Information (CUI)?

The correct reference for guidance on safeguarding Controlled Unclassified Information (CUI) is found in DoDM 5200.01 v4. This document outlines the Department of Defense's policies and procedures for the protection of sensitive information, including CUI, ensuring that employees have a clear framework to follow.

By consulting this manual, employees can gain a deeper understanding of their responsibilities associated with handling and protecting CUI, as it covers various aspects such as classification, markings, and the safeguarding measures required to maintain the integrity and confidentiality of this type of information.

While other documents may contain relevant information or pertain to different aspects of security within the DoD, DoDM 5200.01 v4 is specifically focused on CUI and is the authoritative guide that employees should rely on. Thus, it provides the most pertinent information for ensuring compliance with policies related to the protection of Controlled Unclassified Information.
