Check Text (C-258057r1045146_chk)
Verify RHEL 9 is configured to lock an account until released by an administrator after three unsuccessful logon attempts with the command:
$ sudo grep -w 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.
