Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly enforces authorization decisions so users cannot retrieve workflow instance data from unauthorized projects.
Limits privileges granted to users, reducing the chance that an account can reach workflow data outside its assigned projects.
Enforces information-flow rules between projects, blocking unauthorized retrieval of workflow instance information.

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

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