Check Text (C-261365r996541_chk)
Verify SLEM 5 enforces a delay of at least five seconds between logon prompts following a failed logon attempt with the following command:
> grep pam_faildelay /etc/pam.d/common-auth
auth required pam_faildelay.so delay=5000000
If the value of "delay" is not set to "5000000" or greater, "delay" is missing, the line is commented out, or the "pam_faildelay" line is missing completely, this is a finding.
Fix Text (F-65002r995961_fix)
Configure SLEM 5 to enforce a delay of at least five seconds between logon prompts following a failed logon attempt.
Add or modify the following line in the "/etc/pam.d/common-auth" file:
auth required pam_faildelay.so delay=5000000
