Audit logging is the recording of system, user, administrative, or application actions in a way that supports review, investigation, and accountability. It matters because defenders cannot investigate or verify what happened if meaningful actions leave no trustworthy trail.
What is Audit Logging?
Audit logs capture security-relevant events such as logins, configuration changes, access to sensitive data, administrative actions, and other important system behavior. Strong audit logging helps with detection, forensics, governance, and compliance.
What Audit Logging Commonly Covers
Common events include authentication activity, privilege changes, policy changes, data access, account lifecycle actions, API calls, and system configuration modifications.
Audit Logging vs. General Logging
General logging may capture operational or debugging data. Audit logging focuses more specifically on traceability, accountability, and security-relevant actions.
