you have added the custom attack object to the database, you can search using these
keywords to quickly locate the attack.

use an attack object in a policy, you can specify what action the IDP device should take

or ScreenOS 6.0 or later, you can tell the device to use the action recommended by
Juniper Networks for that attack.
