Final answer:
The Code of Federal Regulations that covers CUI, particularly in 32 CFR Part 2002, provides guidelines for federal agencies on handling such information, including designation, marking, and safeguarding.
Step-by-step explanation:
The Code of Federal Regulations (CFR) that covers Controlled Unclassified Information (CUI) is specified in multiple titles, as CUI pertains to various sectors regulated by the U.S. government. However, the specific guidelines and policies for handling CUI are largely outlined in 32 CFR Part 2002, "Controlled Unclassified Information." This part was established by the National Archives and Records Administration (NARA) and provides the guidelines federal agencies must follow in managing and safeguarding CUI. It includes the designation, marking, safeguarding, decontrolling, and rules for sharing CUI with non-federal entities. Additionally, other titles in the CFR may also provide supplementary regulations depending on the nature of the CUI and the involved federal agency.
