**CUI** stands for [**Controlled Unclassified Information**](https://www.cybersaint.io/dfars-and-cmmc/controlled-unclassified-information), which is any type of data that requires safeguarding consistent with applicable laws, regulations, and government-wide policies.

[NIST 800-171](https://www.cybersaint.io/cybersecurity/frameworks-and-standards/nist/glossary/what-is-nist-800-171) outlines security controls and details how organizations should safeguard CUI. These controls cover things like access control, incident response, and risk assessment. DFARS clause 252.204-7012 mandates that DoD contractors who handle CUI must implement the security controls outlined in NIST 800-171. This ensures a standardized approach to protecting sensitive information throughout the defense supply chain.
