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
( https://mysecurity.zyxel.com )
