What is the scope of DoD Instruction 5200.48?

• A. It applies to DoD components and contractor personnel who handle CUI.
• B. It applies only to DoD civilian employees.
• C. It applies only to military personnel.
• D. It applies to all government agencies.

Answer: (A)

This instruction defines who must follow its rules for protecting Controlled Unclassified Information. It applies to DoD components and any contractor personnel who handle CUI, ensuring that both DoD organizations and external workers under DoD contracts implement the same safeguarding, labeling, storage, transmission, and incident reporting requirements. It isn’t limited to DoD civilian employees or to military personnel alone, and it doesn’t cover all government agencies—those have their own policies. Including contractor personnel keeps everyone with access to DoD’s CUI under the same protective standards, reducing the risk of mishandling or exposure.
