J-Security Center Updates Overview
The Juniper Networks Security Center (J-Security Center) routinely makes important updates available to IDP security policy components, including updates to the IDP detector engine and the NSM attack database.
The IDP detector engine is a dynamic protocol decoder that includes support for decoding more than 60 protocols and more than 500 service contexts. You should update IDP detector engine when you first install IDP, whenever you upgrade, and whenever alerted to do so by Juniper Networks. You can view release notes for detector engine updates at http://www.juniper.net/techpubs/software/management/idp/de/.
The NSM attack database stores data definitions for attack objects. Attack objects are patterns comprising stateful signatures and traffic anomalies. Security policy rules direct the IDP engine to inspect traffic for attack objects. We recommend you schedule automatic updates for the NSM attack database.
