Assessment Title

Rule Text

The /etc/syslog.conf file must be group-owned by root, bin, or sys.

Description

Discussion Text

If the group owner of /etc/syslog.conf is not root, bin, or sys, unauthorized users could be permitted to view, edit, or delete important system messages handled by the syslog facility.

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

Checks

DISA STIG (Manual Reference)

Check /etc/syslog.conf group ownership.

Procedure:
# ls -lL /etc/syslog.conf

If /etc/syslog.conf is not group-owned by root, sys, or bin, this is a finding.

Remediation

Change the group owner of the /etc/syslog.conf file to root, bin, or sys.

Procedure:
# chgrp root /etc/syslog.conf
