AC-24 Access Control Decisions
Ensures decisions to grant supply chain access are made on defined attributes rather than on the strength of a commercial relationship.
Source: NIST SP 800-161 Rev 1 (supply chain), AC-24. The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open NIST SP 800-161 Rev 1 (supply chain) in the compliance library.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.
