Enable IDP on Juniper SRX Devices Managed by Juniper Space

An Intrusion Detection and Prevention (IDP) policy lets you selectively enforce various attack detection and prevention techniques on the network traffic passing through your SRX Series. The SRX Series offer the same set of IDP signatures that are available on Juniper Networks IDP Series Intrusion Detection and Prevention Appliances to secure networks against attacks. The basic IDP configuration involves the following tasks:

  • Download and install the IDP license.
  • Download and install the signature database—You must download and install the IDP signature database. The signature databases are available as a security package on the Juniper Networks website. This database includes attack object and attack object groups that you can use in IDP policies to match traffic against known attacks.
  • Configure recommended policy as the IDP policy—Juniper Networks provides predefined policy templates to use as a starting point for creating your own policies. Each template is a set of rules of a specific rulebase type that you can copy and then update according to your requirements.
  • To get started, we recommend you use the predefined policy named “Recommended”.
  • Enable a security policy for IDP inspection—For transit traffic to pass through IDP inspection, you configure a security policy and enable IDP application services on all traffic that you want to inspect.
1. License

Juniper Support has some License Management Online Tools available on their website:


Click https://lms.juniper.net/lcrs/license.do should get you the classic Generate Licenses, but for newer hardware, it has been moved to new site: https://license.juniper.net/licensemanage



After got the license file, you will just need to add it SRX device from command line:

2. Install Signature Database

Make sure you have download latest signature database in your Juniper Space Security Director.

You may need to probe the SRX devices to find out the one you just installed license.





{primary:node0}
john@fw-ptest-1> show security idp security-package-version 
node0:
--------------------------------------------------------------------------

  Attack database version:3027(Thu Jan 18 13:53:07 2018 UTC)
  Detector version :12.6.160171124
  Policy template version :N/A

node1:
--------------------------------------------------------------------------

  Attack database version:3027(Thu Jan 18 13:53:07 2018 UTC)
  Detector version :12.6.160171124
  Policy template version :N/A



3. Create and Install Policy

3.1 You can use Juniper Space Security Director to create your first IPS policy. There are different type of templates to be used as an example.

3.2 Publish IPS policy and Update it to device






{primary:node0}
john@fw-ptest-1> show security idp policies 
node0:
--------------------------------------------------------------------------
ID    Name                   Sessions    Memory      Detector       
 0     Space-IPS-Policy       0           5667667     12.6.160171124

node1:
--------------------------------------------------------------------------
ID    Name                   Sessions    Memory      Detector       
 0     Space-IPS-Policy       0           5667667     12.6.160171124




4. Enable IPS option on Firewall Rules
This is the last step, for each firewall rule, there is column 'advanced security' to allow you to enable IPS on this rule.
