Which type of event is essential for tracking changes made to a system?

Tracking changes made to a system is crucial for maintaining security, compliance, and overall system integrity. Audit events serve this purpose effectively, as they specifically record and provide detailed information on actions taken within a system, including user activities, configuration changes, and access attempts.

These events are instrumental in governance and monitoring, allowing administrators to trace who made a change, what the change was, and when it occurred. This is important for forensic analysis, compliance reporting, and troubleshooting, as it provides a clear trail of accountability.

While warning, error, and information events provide useful insights into system performance and issues, they do not specifically focus on tracking changes or actions taken within the system. Warnings may indicate potential problems, errors highlight failures, and informational messages provide general updates or status reports. However, none of these categories directly corresponds to the examination of changes and activities crucial for security and compliance purposes like audit events do.
