Check Text (C-234983r991588_chk)
Verify the SUSE operating system enforces a delay of at least four seconds between logon prompts following a failed logon attempt.
> grep pam_faildelay /etc/pam.d/common-auth
auth required pam_faildelay.so delay=4000000
If the value of "delay" is not set to "4000000", "delay" is commented out, "delay" is missing, or the "pam_faildelay" line is missing completely, this is a finding.
Fix Text (F-38134r619219_fix)
Configure the SUSE operating system to enforce a delay of at least four seconds between logon prompts following a failed logon attempt.
Edit the file "/etc/pam.d/common-auth".
Add a parameter "pam_faildelay" and set it to:
> delay is in micro seconds
auth required pam_faildelay.so delay=4000000
