Fix Recommendation

Configure the audit log directory to have a mode of "0750" 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 path of the directory containing the audit logs, configure the audit log directory to have a mode of "0750" or less permissive by using the following command:

# chmod -R g-w,o-rwx /var/log/audit

Check Contents

Verify that the audit log directory has a mode of "0750" 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 path of the directory containing the audit logs, check if the directory has a mode of "0750" or less by using the following command:

# sudo stat -c "%n %a" /var/log/audit
/var/log/audit 750

If the audit log directory has a mode more permissive than "0750", this is a finding.
