What log contains auditing and log-on information for a system?

The security log is specifically designed to record audit and logon events for a system. This includes important details such as successful and failed login attempts, which are crucial for tracking user access and potential security breaches. The security log allows administrators to monitor activity that pertains to the security of the system, ensuring that any unauthorized access can be identified and addressed promptly.

While other types of logs like the event log may contain a variety of information regarding system events and errors, they do not specifically focus on security-related auditing and logon events. The system log typically records operational and system-level messages, while the access log is more often associated with tracking requests made to a web server rather than system user access. Therefore, the security log stands out as the most relevant option for auditing and log-on information.
