Mitigating Controls (NIST 800-53 r5) AI

Least privilege directly requires that only the minimal necessary privileges are assigned to each actor.

Account management defines and authorizes the exact privileges granted to each account or role.

Enforces only the authorizations that were assigned, so correct assignment is a prerequisite.

Separation of duties constrains which privilege combinations may be assigned to any actor.

PR.AA-05 full match
prevents

Directly enforces least-privilege policy definition, management, and review that prevents incorrect privilege assignments.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

The access-rights control governs the entire lifecycle of privilege assignment, directly eliminating incorrect assignments.

prevents

Privileged-access-rights control explicitly requires least-privilege assignment and ongoing validation, directly mitigating CWE-266.

prevents

Access control policy directly prevents incorrect privilege assignment by defining who may receive which rights.

mitigates

Segregation of duties reduces blast radius of any single incorrect privilege but does not prevent the assignment itself.

mitigates

Restricting privileged utility programs limits exposure from over-privileged accounts but does not address how privileges are assigned.

prevents

Information-access-restriction mechanisms enforce the correct privilege boundaries once assignment rules are defined.
