Check Content

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

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
