Fix Recommendation

Configure the audit log and audit log directory to be protected from unauthorized read access, by setting the correct owner as "root" with the following command:

$ sudo chgrp root [audit_log_file]

Replace "[audit_log_file]" to the correct audit log path, by default this location is "/var/log/audit/audit.log."

Configure the audit log to be owned by root by configuring the log group in the /etc/audit/auditd.conf file:

log_group = root

Check Contents

Verify the audit logs are owned by group root.

First, determine where the audit logs are stored with the following command:

$ sudo grep -iw log_file /etc/audit/auditd.conf
log_file = /var/log/audit/audit.log

Using the location of the audit log file, check if the audit log is owned by group "root" with the following command:

$ sudo ls -l /var/log/audit/audit.log
-rw------- 1 root root 908084 Jul 19 23:10 /var/log/audit/audit.log

If the audit log is not owned by group "root", this is a finding.
