IDP Profiles
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
Base IDP profiles are templates that you use to create new IDP profiles.The
ZyWALL comes with several base profiles. See Table 143 on page 484 for details
on base profiles.
IDP Policies
An IDP policy refers to application of an IDP profile to a traffic flowing from one
zone to another.
Applying Your IDP Configuration
Changes to the ZyWALL’s IDP settings affect new sessions (not the sessions that
already existed before you applied the changed settings).

30.1.3 Before You Begin
• Register for a trial IDP subscription in the Registration screen (see Section
10.2 on page 211). 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.
