Fix Recommendation

Ensure the permissions on the System event log (System.evtx) are configured to prevent standard user accounts or groups from having greater than Read access. 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" directory.

If the location of the logs has been changed, when adding Eventlog to the permissions, it must be entered as "NT Service\Eventlog".

Check Contents

Verify the permissions on the System event log (System.evtx). Standard user accounts or groups must not have greater than Read access. 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" directory. They may have been moved to another folder.

If the permissions for these files are not as restrictive as the ACLs listed, this is a finding.
