Check Text (C-281197r1166543_chk)
Verify RHEL 10 is configured to lock an account after three unsuccessful login attempts until released by an administrator with the following command:
$ sudo grep 'unlock_time =' /etc/security/faillock.conf
unlock_time = 0
If the "unlock_time" option is not set to "0", or the line is missing or commented out, this is a finding.
