 The Energize Updates page allows you to manage and view the status of all the definition updates on the Barracuda Web Application Firewall:

  • Attack Definition Updates -The Barracuda Threat Intelligence Service uses the attack definitions to provide updates to the Barracuda Web Application Firewall security engine. The updates include updates to the Smart Signatures for injection attacks and signatures for bot detection.
  • Virus Definition Updates - The definitions include virus signatures used by the Anti-Virus engine within the Barracuda Web Application Firewall. It checks file uploads for embedded viruses.
  • Security Definition Updates - The definitions secure the Barracuda Web Application Firewall system.
  • GeoIP Definition Updates - Based on the registration information of the public IP address, the geographical region of the client can be identified using the Geo location database. The definitions include updates to the Geo IP database that is used for multiple product capabilities like allowing or denying of traffic based on geo-IP information.

The following information and actions are available for each kind of definition update, with the exception of Previously Installed Version, which is not available for Security Definition Updates:

  • Current Installed Version - Version of the definition currently installed on the Barracuda Web Application Firewall. It also contains a link, if available, to the "Release Notes" for these definitions.

  • Previously Installed Version - Version of the last definition that was installed on the Barracuda Web Application Firewall.
  • Automatic Update - Set to On for automatic update of that set of definitions whenever they are available, or Off to disable automatic updates.
