Check Text ( C-4328r1_chk )
The event log files “AppEvent.Evt,” “SecEvent.Evt,” and “SysEvent.Evt”— by default, all found in the “%SystemRoot%\SYSTEM32\CONFIG” directory. They may have been moved to another folder. Check for the following permissions: Administrators RX (Auditor’s group) All SYSTEM All Note: See V-1137 for the Auditors group requirement. The “Auditors” group may appear in the Gold Disk output as a finding. This is because the name of the group is left to the sites. If an auditors group is present, its presence doesn’t constitute a finding. If the permissions for these files are not as restrictive as the ACL listed, then this is a finding.
