Audit Trail

Chronological record of system activities that allows reconstruction of events and accountability.

Definition

Audit trails capture who did what, when, and from where, supporting detective controls, investigations, and nonrepudiation. They must be protected from alteration and retained according to policy and regulation.

Example

Database logs record that an administrator changed a salary field at 2:13 a.m.

Exam tip

Protecting logs from modification by the people being monitored is critical.
