Check Text (C-281179r1166489_chk)
Verify RHEL 10 enforces a delay of at least four seconds between console login prompts following a failed login attempt with the following command:
$ sudo 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-85645r1166488_fix)
Configure RHEL 10 to enforce a delay of at least four seconds between login prompts following a failed console login attempt.
Modify the "/etc/login.defs" file to set the "FAIL_DELAY" parameter to "4" or greater:
FAIL_DELAY 4
