AC-3(7) Access enforcement | role-based access control
What the standard requires
Enforce a role-based access control policy over defined subjects and objects and control access based upon [organization-defined roles and users authorized to assume such roles].
Quoted verbatim from NIST SP 800-53 Rev 5 (OSCAL catalog), which is in the public domain.
Cross-framework mappings
No cross-framework mapping is seeded for this control. That is stated rather than filled in: a mapping nobody authored is worse than a gap you can see.
Track AC-3(7) with evidence behind it
In CMDash this control is a row with an owner, a status, uploaded evidence kept with its full history, and an export an assessor can read.
