How does DoD Instruction 5200.48 support governance of CUI across the DoD?

• A. By establishing standardized policy, roles, and procedures for designation, marking, safeguarding, dissemination, decontrol, incident response, and enforcement.
• B. It provides encryption algorithms only.
• C. It prohibits sharing CUI with any external entity.
• D. It focuses on unrelated topics.

Answer: (A)

The main idea is that this instruction creates a unified governance framework for CUI across the DoD by laying out standardized policy, roles, and procedures for designation, marking, safeguarding, dissemination, decontrol, incident response, and enforcement. It clarifies who is responsible for each aspect of CUI management, how CUI is identified and labeled, and the protective measures and handling rules that must be followed to prevent unauthorized access or disclosure. It also defines how sharing is controlled—who may receive CUI and under what conditions, including authorized external recipients—and how a CUI item can be decontrolled when appropriate. The instruction establishes processes for reporting and responding to incidents and for enforcing compliance, creating consistency and accountability across DoD components. It isn’t about encryption algorithms or cryptographic specifics, which are addressed by separate standards; and it does not prohibit sharing in general, but governs sharing under approved policies rather than treating dissemination as forbidden.
