NOTES:

Audit trails may be generated automatically or manually. Their significance depends upon completeness, accuracy, integrity, retention policies, accessibility, and the ability to associate events with identities, systems, or actions.

CONTROL TEXT OBSERVATION:

Observation records events. Audit trails record sequences of responsibility. An audit trail functions as an accountability-preservation mechanism that transforms actions into permanent histories. Through audit trails, past behavior becomes reconstructable, decisions become reviewable, and activities become traceable across time, enabling verification, investigation, governance, and institutional memory.
