Requirement text

NIST SP 800-171 Rev 3; 32 CFR 2002.14(g)

What it means

For CUI on nonfederal information systems, NIST SP 800-171 is the control set the government expects. Revision 3 (2024) reorganized the families and tightened several controls; DFARS 252.204-7012 and 32 CFR 2002.14(g) make it contractually and regulatorily binding for many contractors. A System Security Plan and POA&M are the core evidence artifacts.
