Which description correctly defines Controlled Unclassified Information (CUI)?

• A. Information that is handled using safeguarding controls
• B. Highly sensitive information requiring top-level clearance
• C. Official information that is publicly releasable
• D. Information with no safeguarding requirements

Answer: (A)

Controlled Unclassified Information is unclassified material that still needs protection through specific safeguarding and dissemination controls to prevent unauthorized disclosure. It isn’t about classification levels, but about how the information must be handled, stored, transmitted, and shared. The description that fits this concept best is information that is handled using safeguarding controls, because the emphasis is on protecting the data even though it isn’t classified.

Why the other ideas don’t fit: highly sensitive information that requires top-level clearance describes classified material, which is outside the scope of CUI. Information that is publicly releasable implies there are no restrictions on who can see it, so it wouldn’t require the safeguarding controls that define CUI. Information with no safeguarding requirements would ignore the essential protection aspect of CUI, which is precisely what the safeguarding and dissemination controls are for.
