ZyWALL USG 2000 User’s Guide

An IDP profile is a set of related IDP signatures that you can activate as a set and 
configure common log and action settings. You can apply IDP profiles to traffic 
flowing from one zone to another. For example, apply the default LAN_IDP profile 
to any traffic going to the LAN zone in order to protect your LAN computers.

Note: You can only apply one IDP profile to one traffic flow.

Base IDP profiles are templates that you use to create new IDP profiles.The 
ZyWALL comes with several base profiles. See 

 for details 

on base profiles.

An IDP policy refers to application of an IDP profile to a traffic flowing from one 
zone to another.

Changes to the ZyWALL’s IDP settings affect new sessions (not the sessions that 
already existed before you applied the changed settings).

signatures. 

• Register for a trial IDP subscription in the Registration screen (see 

). This gives you access to free signature updates. This is 

important as new signatures are created as new attacks evolve. When the trial 

subscription expires, purchase and enter a license key using the same screens 

to continue the subscription.
