Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Mandating explicit authorization of mobile device connections reduces the risk of improper authorization decisions for system access.
Ensures authorization decisions are always performed by a complete and analyzable reference monitor.
Auditing session actions allows identification of improper authorization decisions and enforcement failures.
The process verifies authorization mechanisms function as intended before system approval.
By limiting enabled features to only those needed, the control strengthens authorization by removing opportunities for unauthorized use of excess functionality.
Dedicated authorization servers support policy-based decisions, mitigating improper authorization.
Protecting the shutoff from unauthorized activation enforces proper authorization for this critical operation.
