Controlled Unclassified Information (CUI) is sensitive but unclassified U.S. government data protected under NIST SP 800-171 and the CUI program.
Controlled Unclassified Information (CUI) Definition: Controlled Unclassified Information (CUI) is sensitive but unclassified U.S. government data protected under NIST SP 800-171 and the CUI program.
Controlled Unclassified Information (CUI) is U.S. government information that requires safeguarding or dissemination controls under law, regulation, or government-wide policy but is not classified. The CUI program is overseen by NARA, and contractors handling CUI in nonfederal systems must implement the security requirements in NIST SP 800-171. Proper marking, access control, and protection of CUI are central to compliance regimes such as CMMC for the defense industrial base.
Controlled Unclassified Information (CUI) is one of the topics you'll master in the Official ISC2 CISSP Boot Camp.
