Fix Recommendation

Configure the audit log to be protected from unauthorized read access by setting the correct permissive mode with the following command:

$ sudo chmod 0600 [audit_log_file]

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

Check Contents

Verify the audit logs have a mode of "0600" or less permissive.

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 has a mode of "0600" or less permissive 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 has a mode more permissive than "0600", this is a finding.
