NIST SP 800-171 is a US standard specifying security requirements for protecting Controlled Unclassified Information (CUI) in nonfederal systems and organizations. It defines control families spanning access control, incident response, and configuration management for contractors handling government data. Data center and cloud providers supporting the US defense supply chain implement its requirements, which also underpin the CMMC certification program.
