Click Licensing > Update > IDP/AppPatrol to display the following screen.
The ZyWALL comes with signatures for the IDP and application patrol features. These
signatures are continually updated as new attack types evolve. New signatures can be
downloaded to the ZyWALL periodically if you have subscribed for the IDP/AppPatrol
signatures service.
You need to create an account at myZyXEL.com, register your ZyWALL and then subscribe
for IDP service in order to be able to download new packet inspection signatures from
myZyXEL.com (see the Registration screens). Use the Update IDP /AppPatrol screen to
schedule or immediately download IDP signatures.
