How to Override the Risk Classification of an Application

  • Last updated on

Every application pattern delivered with the Barracuda NG Firewall's Application Control 2.0 database contains a risk classification. The risk classification extends the category of each application, to allow an even more granular classification of single applications. Depending on the common usage and reputation, the risk classification may vary from 1 (low risk) to 4 (high risk).

Let's take the category File Storage and Backup as an example: Cloud storage is more popular than ever and sometimes even an integral part of modern business communication. But depending on the business model of cloud storage services, some of them are highly attractive for illegal and extremely bandwidth consuming file sharing activities. While Copy and Amazon Web Services enjoy a good reputation, others like DepositFiles or Mega have a poor reputation. Transforming these reputations into risk categories, allows you to only allow services with a good reputation.

Barracuda Networks continuously observes web application reputations and keeps you up to date with the latest risk classifications. However, in some cases it may be necessary to manually override risk classification.

Override the Risk Level of an Application

  1. Click the Config tab. The Configuration Overview page opens in the Simple Config view.
  2. In the Operational Configuration table, click Ruleset in the Firewall section.
  3. In the left navigation pane, expand Firewall Objects and click Applications.
  4. Change the risk level of an application by either right-clicking it and selecting Override this Application or using the icons in the top-right area of the rule set.
  5. Select the new risk level for the application and then click OK.

 The following figure displays process of overriding the risk classification of an application.
