Check Text (C-281194r1166534_chk)
Verify RHEL 10 is configured to lock an account after three unsuccessful login attempts with the following command:
$ sudo grep 'deny =' /etc/security/faillock.conf
deny = 3
If the "deny" option is not set to "3" or less (but not "0"), or is missing or commented out, this is a finding.
Fix Text (F-85660r1166533_fix)
Configure RHEL 10 to lock an account when three unsuccessful login attempts occur.
Add/modify the "/etc/security/faillock.conf" file to match the following line:
deny = 3
