Fix Recommendation

Navigate to and open:

/etc/pam.d/system-auth

Add or update the following line:

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.

Check Contents

At the command line, run the following command to verify the pam_faildelay.so module is used:

# grep '^auth' /etc/pam.d/system-auth

Example result:

auth required pam_faillock.so preauth
auth required pam_unix.so
auth required pam_faillock.so authfail
auth optional pam_faildelay.so delay=4000000

If the pam_faildelay.so module is not present with the delay set to at least four seconds, this is a finding.

Note: The delay is configured in milliseconds.
