The National Archives and Records Administration (NARA) serves as the authoritative body overseeing the Controlled Unclassified Information (CUI) program within the United States federal government. NARA maintains the CUI Registry, which is the definitive resource for all categories, subcategories, and associated markings of CUI. This registry provides comprehensive guidance on the identification and handling of CUI, ensuring standardized practices across federal agencies and their contractors.
The other options are delineated as follows:
CMMC-AB:The Cybersecurity Maturity Model Certification Accreditation Body is responsible for overseeing the CMMC program but does not manage CUI classifications.
DoD Contractors FAQ:While it may offer guidance to Department of Defense contractors, it is not an authoritative source for CUI data classifications.
OSC's privacy policies:An Organization Seeking Certification's internal policies pertain to its own data handling practices and are not authoritative for CUI classifications.
Therefore, for authoritative information on CUI data classifications, the NARA's CUI Registry is the appropriate resource.
