Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly enforces authorization decisions so secondary users cannot read owner Wi-Fi passwords stored on the tablet.
Requires least-privilege assignment so secondary accounts receive no access to another user's saved credentials.
Mandates access-control measures specific to mobile devices, including protection of sensitive stored data such as Wi-Fi passwords.

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.
