Download the Signature Database

 Note

This topic is applicable only for the CSO on-premises version. For CSO SaaS, you can skip this task because the signature database is downloaded by the Juniper Networks team.

The signature database that Juniper Networks provides contains application and intrusion prevention system (IPS) signatures:

  • Application signatures are definitions of predefined attacks and applications, and can be used to identify applications for tracking firewall policies and quality-of-service (QoS) prioritization.

  • IPS signatures are definitions of predefined attack object and attack object groups that you can use in IDP policies to match traffic against known attacks.

To download the signature database:

  1. Select Administration > Signature Database.

    The Signature Database page appears.

  2. Click Signature Download Settings.

    The Signature Download Settings page appears.

  3. Enter the download settings according to the guidelines provided in Table 1.
  4. Click OK to save the changes:
    • If you specified that the signature database should be downloaded immediately, a Job Tasks page appears displaying information about the signature download job. Click OK to close this page and return to the Signature Database page.

    • If you scheduled the signature download for later, a job is triggered and you are returned to the Signature Database page. A confirmation message (with the job ID) is displayed at the top of the page.

    After the signature download operation is complete, predefined signatures (application and IPS) and IPS profiles are available in CSO. You cannot modify predefined signatures or IPS profiles.
