PHTN-40-000206 - The Photon operating system must enforce a delay of at least four seconds between logon prompts following a failed logon attempt.

Information

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

Solution

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.
