Did you notice that Juniper has updated their IDP policy templates?
First lets review the list of old of pre-defined templates..
blogger@SRX> show security idp policy-templates-list
Web_Server

IDP_Default
Recommended
Lets check the version of that template..
blogger@SRX> show security idp security-package-version
Attack database version:2395(Wed Jul 2 18:14:04 2014 UTC)
Detector version :12.6.160140626
Policy template version :2192
Lets check and see whats available..
blogger@SRX> request security idp security-package download check-server

Version info:2395(Detector=12.6.160140626, Templates=2395)
So you see, even if you are automatically updating the attack database that doesn't update the policy templates.
