Discussion

To prevent unauthorized access or manipulation of system audit logs, the tools for manipulating those logs must be protected.

Check Content

Verify the audit tool executables are group-owned by root, bin, sys, or system.

Procedure:
# ls -lL /sbin/auditctl /sbin/auditd /sbin/ausearch /sbin/aureport /sbin/autrace /sbin/audispd 

If any listed file is not group-owned by root, bin, sys, or system, this is a finding.

Fix Text

Change the group-owner of the audit tool executable to root, bin, sys, or system.

Procedure:
# chgrp root <audit tool executable>
