Check Text (C-269217r1050099_chk)
Verify AlmaLinux OS 9 enforces a delay of at least four seconds between console logon prompts following a failed logon attempt with the following command:
$ grep -i fail_delay /etc/login.defs
FAIL_DELAY 4
If the value of "FAIL_DELAY" is not set to "4" or greater, or the line is commented out, this is a finding.
Fix Text (F-73149r1049329_fix)
Configure the AlmaLinux OS 9 to enforce a delay of at least four seconds between logon prompts following a failed console logon attempt.
Modify the "/etc/login.defs" file to set the "FAIL_DELAY" parameter to 4 or greater:
FAIL_DELAY 4
