Fix Recommendation

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 a value of "4000000" or greater:

# delay is in micro seconds
auth required pam_faildelay.so delay=4000000

Check Contents

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" or greater, "delay" is commented out, "delay" is missing, or the "pam_faildelay" line is missing completely, this is a finding.
