Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authorization decisions on proxy repository configuration objects so a delegated administrator cannot read upstream credentials.

prevent

Limits privileges granted to delegated repository administrators, preventing assignment of rights that would expose stored proxy credentials.

prevent

Enforces information-flow rules that block credential data from being returned to any subject lacking explicit need-to-know.

PR.AA-05 mostly match
prevents

Defining, enforcing, and reviewing access authorizations and least privilege directly prevents incorrect authorization checks.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

prevents

By tying access rights to identity, device, location and classification, the control reduces the likelihood that an authorization decision will be based on an incorrect or bypassed policy.
