Overview

Finding ID Version Rule ID IA Controls Severity

Description
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 Security event log may disclose sensitive information or be susceptible to tampering if proper permissions are not applied.

Check Text ( C-64287r1_chk )
Verify the permissions on the Security event log (Security.evtx). Standard user accounts or groups must not have 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.
Fix Text (F-69467r1_fix)
Ensure the permissions on the Security event log (Security.evtx) are configured to prevent standard user accounts or groups from having access. The default permissions listed below satisfy this requirement.

Eventlog - Full Control
SYSTEM - Full Control
