CVE-2023-43087

Provides defined handling (alert and additional actions) for the exceptional condition of audit logging failure.

Supplies a concrete handling action (safe mode) for exceptional conditions, mitigating risks from improper or absent handling that could allow continued attacks.

By preparing users for contingency scenarios, the control promotes proper handling of exceptional conditions instead of default or unsafe behaviors.

An updated contingency plan defines current actions for exceptional conditions, reducing the window for attackers to exploit improper handling leading to system failure.

Procedures ensure proper handling of exceptional conditions to support effective incident response.

Incident response testing confirms proper handling of exceptional conditions to limit exploit impact.

Gives users guidance on incident handling, reducing improper handling of exceptional conditions that could stem from exploited weaknesses.

Enforces structured response to exceptional conditions so the system cannot remain in an unsafe state.

Runtime monitoring of software and data surfaces adverse events triggered by unhandled permission failures.

Defining, enforcing and reviewing access permissions with least privilege directly prevents code paths that mishandle insufficient privileges.

Generating logs of permission-related events enables detection and analysis of improper handling.

A.5.15 only requires determining requirements, defining a topic-specific policy on access control, and considering various factors; it does not itself enforce, implement, or prevent exploitation of mishandled insufficient permissions.

Documented operating procedures may specify exception handling but do not guarantee implementation.
