Chapter 14 Intrusion Detection and Prevention (IDP) Screens

ZyWALL 5/35/70 Series User’s Guide

When scheduling signature updates, you should choose a day and time when your network is 
least busy so as to minimize disruption to your network. Your custom signature configurations 
are not over-written when you download new signatures. 

File-based anti-virus signatures (see the anti-virus chapter) are included with IDP signatures. 
When you download new signatures using the anti-virus Update screen, IDP signatures are 
also downloaded. The version number changes both in the anti-virus Update screen and this 
screen. Both screens also share the same Auto-Update schedule. Changes made to the 
schedule in one screen are reflected in the other.

This field displays the signatures version number currently used by the ZyWALL. 
This number is defined by the ZyXEL Security Response Team (ZSRT) who 
maintain and update them.
This number increments as new signatures are added, so you should refer to this 
number regularly. Go to https://mysecurity.zyxel.com/mysecurity/ to see what the 
latest version number is. You can also subscribe to signature update e-mail 
notifications.
