Fix Recommendation

Configure the operating system to include root when locking an account after three unsuccessful logon attempts occur in 15 minutes.

Add/modify the "/etc/security/faillock.conf" file to match the following line:

even_deny_root

Check Contents

Note: This check applies to OL versions 8.2 or newer. If the system is OL version 8.0 or 8.1, this check is not applicable.

Verify the "/etc/security/faillock.conf" file is configured to log user name information when unsuccessful logon attempts occur:

$ sudo grep even_deny_root /etc/security/faillock.conf

even_deny_root

If the "even_deny_root" option is not set or is missing or commented out, this is a finding.
