NIST SP 800-171 Revision 3 is a U.S. government framework that defines security requirements for non-federal organizations to protect Controlled Unclassified Information (CUI) handled by contractors, vendors, and service providers working with federal agencies.

While it traditionally focused on human user access, the latest revision sharpens the focus on non-human identities – like applications, scripts, and service accounts – that drive data flow and system interactions. These identities now far outnumber users and are increasingly targeted in attacks, making their security essential to protecting sensitive information.
