Assessment Title

Rule Text

System audit tool executables must be group-owned by root, bin, or sys.

Description

Discussion Text

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

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Checks

DISA STIG (Manual Reference)

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

Procedure:
# ls -lL /usr/sbin/auditd /usr/sbin/audit /usr/sbin/bsmrecord /usr/sbin/auditreduce /usr/sbin/praudit /usr/sbin/auditconfig

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

Remediation

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

Procedure:
# chgrp root <audit tool executable>
