What is an example of CUI needing 'need-to-know'?

• A. Public policy documents needing none.
• B. DoD Unclassified Nuclear Information (UCNI) requiring need-to-know under referenced policy/regulation.
• C. Information with no dissemination controls.
• D. General administrative data.

Answer: (B)

Need-to-know is an access-control principle that limits who can view information to those whose duties require it. Within CUI, some categories are explicitly governed by need-to-know determinations, even though the information is unclassified. DoD Unclassified Nuclear Information (UCNI) is one such category. Under the referenced policy and regulation, UCNI must be restricted to individuals who have a need to know to perform their official duties. This ensures that sensitive nuclear-related information remains accessible only to those who truly require it, despite its unclassified status. The other options describe information that is not restricted: public policy documents that may require no special access, information with no dissemination controls, or general administrative data. None of these illustrate CUI that requires a need-to-know restriction.
