At the command line, run the following command: # grep pam_faildelay /etc/pam.d/system-auth|grep --color=always "delay=" Expected result: auth optional pam_faildelay.so delay=4000000 If the output does not match the expected result, this is a finding.

Fix Text (F-60161r887302_fix)
Navigate to and open: /etc/pam.d/system-auth Remove any existing "pam_faildelay" line and add the following line at the end of the file: auth optional pam_faildelay.so delay=4000000 Note: On vCenter appliances, the equivalent file must be edited under "/etc/applmgmt/appliance", if one exists, for the changes to persist after a reboot.
