Check

Verify the audit logs directory is owned by "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

Then using the location of the audit log file, determine if the audit log directory is owned by "root" using the following command:

$ sudo ls -ld /var/log/audit

drwx------ 2 root root 23 Jun 11 11:56 /var/log/audit

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

Fix

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

$ sudo chown root /var/log/audit
