IDP Support Notes

What's Pre-defined signature?

Pre-defined signatures are signatures created by ZyXEL Security Response Team (ZSRT). These signatures are attack patterns or misuse network behavior researched and studied by ZSRT, then compiled into a “pre-defined” policy set available for update.

Why should I need to update signature?

Intrusion detection is much like virus protection; an IDP system that hasn’t been updated for a year will miss common new attacks. ZyXEL Security Respose Team (ZSRT) will publish new “pre-defined” policy set on the policy update server (updateidp.zyxel.com). ZyWALL IDP10 is preset to download the latest policy every day automatically.

Where can I get the description of a policy or advisory?

Whenever there are new advisories, policies published by ZyXEL, users can go to mySecurityZone (https://mysecurity.zyxel.com) to check the detailed description. The login user name/password is as login user name/password for http://www.myzyxel.com where users register ZyWALL IDP10.

How do I make sure my ZyWALL IDP10 already gets the latest policy?

You can check the latest policy version on mySecurityZone
