ℹ️ Check
Verify the SUSE operating system enforces a delay of at least four seconds between logon prompts following a failed logon attempt. Check that the SUSE operating system enforces a delay of at least four seconds between logon prompts following a failed logon attempt with the following command: > grep FAIL_DELAY /etc/login.defs FAIL_DELAY 4 If the value of "FAIL_DELAY" is not set to "4", "FAIL_DELAY" is commented out, or "FAIL_DELAY" is missing, then this is a finding.
