addresses: CWE-778

Audit policy requires defining and implementing logging of security-relevant events, directly reducing insufficient logging.

addresses: CWE-778

Providing proof of performed actions necessitates sufficient logging of security-relevant events with attribution details.

addresses: CWE-778

Retaining audit records for a defined period ensures security-relevant events remain available for after-the-fact investigations, directly mitigating the risk that attackers can hide actions due to missing or purged log data.

addresses: CWE-778

Directly requires generation of audit records for specified events, preventing the absence of logging that allows undetected malicious activity.

addresses: CWE-778

Directly implements detailed session logging to address the weakness of insufficient logging.

addresses: CWE-778

Provides alternate logging mechanism to maintain audit trails when primary capability fails, directly reducing insufficient logging.

addresses: CWE-778

Employing coordination mechanisms ensures consistent and sufficient logging practices are applied when audit information crosses organizational boundaries.

addresses: CWE-778

This control requires identifying, specifying, and justifying event types for logging with a focus on adequacy for post-incident investigations, directly mitigating insufficient logging.
