Fix Recommendation

For any log file that returns an incorrect permission value, run the following command:

/usr/bin/sudo chmod 440 [audit log file]

[audit log file] is the full path to the log file in question.

Check Contents

To check the permissions of the audit log files, run the following command:

/usr/bin/sudo ls -le $(/usr/bin/sudo /usr/bin/grep '^dir' /etc/security/audit_control | awk -F: '{print $2}') | /usr/bin/grep -v current

The results should show the permissions (first column) to be "440" or less permissive.

If they do not, this is a finding.
