Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-703

Implements explicit check and handling for the exceptional condition of audit logging process failure.

addresses: CWE-703

Establishing and monitoring system metrics with correlation and response actions helps identify and address improper handling of exceptional conditions.

addresses: CWE-703

Provides a defined response to detected conditions by restricting operation, ensuring exceptional conditions are handled rather than ignored or mishandled.

addresses: CWE-703

Contingency training equips users with defined procedures to check and respond to exceptional conditions during disruptions, reducing exploitation of mishandled errors.

addresses: CWE-703

Testing verifies the system's ability to detect, handle, and recover from exceptional conditions as part of the plan, reducing exploitability of improper exception handling.

addresses: CWE-703

Regular updates keep contingency procedures aligned with system changes, providing structured handling for exceptional conditions that would otherwise allow unmitigated exploitation.

addresses: CWE-703

Policy defines checks and handling for exceptional conditions arising from security incidents.

addresses: CWE-703

Performing IR tests ensures exceptional conditions are properly checked and handled to enable effective response.
