Updating Anti-virus Signatures

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

IDP signatures (see the chapters on IDP) are included with file-based anti-virus signatures. When you download new signatures using the IDP Update screen, anti-virus signatures are also downloaded. The version number changes both in the IDP 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.

Note: The ZyWALL does not have to reboot when you upload new signatures.

Updating IDP and Application Patrol Signatures

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 IDP 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).
