The SUSE operating system must enforce a delay of at least four seconds between logon prompts following a failed logon attempt.

Limiting the number of logon attempts over a certain time interval reduces the chances that an unauthorized user may gain access to an account.

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.

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
