Implements explicit check and handling for the exceptional condition of audit logging process failure.
Provides a defined response to detected conditions by restricting operation, ensuring exceptional conditions are handled rather than ignored or mishandled.
Contingency training equips users with defined procedures to check and respond to exceptional conditions during disruptions, reducing exploitation of mishandled errors.
Performing IR tests ensures exceptional conditions are properly checked and handled to enable effective response.
Mandates explicit, predictable handling of exceptional conditions rather than undefined continuation.
Requires systematic prediction and handling of failure conditions, reducing the impact of unhandled exceptional states.
Regular updates keep contingency procedures aligned with system changes, providing structured handling for exceptional conditions that would otherwise allow unmitigated exploitation.
Policy defines checks and handling for exceptional conditions arising from security incidents.
