Title
Windows Server 2022 permissions for the System event log must prevent access by nonprivileged accounts. (Cat II impact)
Discussion
Maintaining an audit trail of system activity logs can help identify configuration errors, troubleshoot service disruptions, and analyze compromises that have occurred, as well as detect attacks. Audit logs are necessary to provide a trail of evidence in case the system or network is compromised. The System event log may be susceptible to tampering if proper permissions are not applied.

Check Content
Navigate to the System event log file. The default location is the "%SystemRoot%\System32\winevt\Logs" folder. However, the logs may have been moved to another folder. If the permissions for the "System.evtx" file are not as restrictive as the default permissions listed below, this is a finding: Eventlog - Full Control SYSTEM - Full Control Administrators - Full Control
Fix Text
Configure the permissions on the System event log file (System.evtx) to prevent access by nonprivileged accounts. The default permissions listed below satisfy this requirement: Eventlog - Full Control SYSTEM - Full Control Administrators - Full Control The default location is the "%SystemRoot%\System32\winevt\Logs" folder. If the location of the logs has been changed, when adding Eventlog to the permissions, it must be entered as "NT Service\Eventlog".
