Crosswalk
CMMC to NIST Crosswalk
Each CMMC practice with the NIST SP 800-171 Rev 2 requirement it is built on, the Rev 3 counterpart, the SP 800-53 controls behind it and, for Level 3, the SP 800-172 requirement. Open any number to read it.
4 practices. Mappings are the guides' key references and NIST's published relationships; a practice with no mapping yet shows a dash.
