NIST SP 800-53 AI Controls Mapping: The Control IDs an AI Gateway Actually Answers
SP 800-53 Revision 5 organises its catalogue into 20 control families, and the COSAiS overlay work that will tailor it for AI is still in draft. An AI system inside an authorisation boundary is assessed today against control identifiers that already exist. This maps the specific controls an identity-aware gateway on AI traffic satisfies, at the AC-3, AC-4, AU-3, AU-9, IA-2, SC-7, SI-4 and SR-3 level, and names the ones it contributes nothing to.
