Fix Recommendation

Log in to the server virtual console and navigate to the "/etc/pam.d/" folder.

Move the current configuration and make new copies to be edited by executing the following commands:

sudo cp password-auth password-auth-as

sudo cp system-auth system-auth-as

Edit the files "password-auth" and "system-auth".

Add the lines:
auth required pam_faillock.so preauth silent audit deny=3 even_deny_root fail_interval=60 unlock_time=900
after line
auth required pam_env.so

Add:
auth required pam_faillock.so authfail audit unlock_time=900
after
auth sufficient pam_unix.so nullok

Add:
account required pam_faillock.so
before
account required pam_unix.so

The files "system-auth" and "password-auth" are identical, so the procedure can be done on one of the files and copied to the second one.

Restart sssd service:
sudo systemctl restart sssd.service

Check Contents

Log in to the HYCU VM console and go to the "/etc/pam.d/" folder. Verify that "password-auth" and "system-auth" contain the following three lines, and the values for deny and unlock_time are as shown.

Commands:
sudo grep pam_faillock.so /etc/pam.d/password-auth
sudo grep pam_faillock.so /etc/pam.d/system-auth

Both should displays the following three lines:
auth required pam_faillock.so preauth silent audit deny=3 even_deny_root fail_interval=60 unlock_time=900
auth required pam_faillock.so authfail audit unlock_time=900
account required pam_faillock.so

If the required content is not present, this is a finding.
