Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces authorization decisions so users cannot retrieve workflow instance data from unauthorized projects.

prevent

Limits privileges granted to users, reducing the chance that an account can reach workflow data outside its assigned projects.

prevent

Enforces information-flow rules between projects, blocking unauthorized retrieval of workflow instance information.

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.
