How to Update Definitions Under Energize Updates

  • Last updated on

Energize Updates delivers the latest attack, virus, security, update, and location definitions from Barracuda Central to protect your Barracuda Load Balancer ADC. On the ADVANCED > Energize Updates page, you can choose to automatically or manually update each definition:

  • To let a definition sync automatically whenever a new version is available, enable the Automatic Updates setting for it.
  • If you want to manually update a definition, disable the Automatic Updates setting for it. You can manually update a definition online at any time. If offline updates are enabled, you can complete offline updates of the definitions. 

For maximum protection, Barracuda Networks recommends that you enable Automatic Updates for each set of definitions, so that you receive the latest versions as soon as they are available from Barracuda Central.

Activating the Attack Definition

After you update the Attack Definition (automatically or manually), you must activate it by clicking the Activation link that displays on the BASIC > Status or ADVANCED > Energize Updates page. During the activation of the Attack Definition, the data path traffic may be interrupted, possibly dropping incoming packets for a few seconds.

For the updates of all other definitions, traffic is processed normally.

The Security Definition Updates under Energise Updates is no longer applicable on the Barracuda ADC as the updates for the product are included in the firmware. Ensure that the firmware is upgraded to the latest GA release so that all security updates are available for the product. Any updates showing up in the Barracuda ADC Web Interface for Security Definitions can be safely ignored. The web interface will be modified to hide the Security Definitions in an upcoming release.


Configure Automatic Definition Updates

To enable and disable automatic updates:

  1. Go to the ADVANCED > Energize Updates page.
  2. In the section for each definition that you want to automatically update, set Automatic Updates to On. The definition will automatically update whenever a new version is available.
  3. In the section for each definition that you do not want to automatically update, set Automatic Updates to Off. You must then manually update the definition whenever a new version is available. You can update definitions online and offline.
  4. Click Save.

Manually Update Definitions Online

To manually update definitions online:

  1. Go to the ADVANCED > Energize Updates page.
  2. In the section for each definition, compare the installed version to the latest general release version available. If you have the latest definition version already installed, the Update button for the latest version is disabled.
  3. If there is a new version available, click Update to update the definition immediately.

Manually Update Definitions Offline
