Vulnerability 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.Satisfies: SRG-OS-000057-GPOS-00027, SRG-OS-000058-GPOS-00028, SRG-OS-000059-GPOS-00029

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 non-privileged 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".

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
