Fix Recommendation

Configure the operating system to include the use of the pam_faillock.so module in the /etc/pam.d/password-auth file.

Add/Modify the appropriate sections of the "/etc/pam.d/password-auth" file to match the following lines:
Note: The "preauth" line must be listed before pam_unix.so.

auth required pam_faillock.so preauth
auth required pam_faillock.so authfail
account required pam_faillock.so

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 pam_faillock.so module is present in the "/etc/pam.d/password-auth" file:

$ sudo grep pam_faillock.so /etc/pam.d/password-auth

auth required pam_faillock.so preauth
auth required pam_faillock.so authfail
account required pam_faillock.so

If the pam_faillock.so module is not present in the "/etc/pam.d/password-auth" file with the "preauth" line listed before pam_unix.so, this is a finding.
