How to Configure Rules

  • Last updated on

This article explains how to create, edit, or delete rules. You may want to refer to Creating Rules for the Barracuda Web Security Service which explains some considerations before creating rules.

Creating Rules

To create a rule, you need to be logged in to your customer account at Barracuda Networks. In the Barracuda Web Security Service Manager interface, click the Rules tab, Click Add New Rule.then do the following steps:

Enter a Name for the new rule.

In the Applies To area, select who the rule Applies To:

  • Everyone—Applies the rule to all users in a network. Unless you have configured authentication, this is your only option. To configure authentication, refer to How to Configure Authentication or Authentication with the Barracuda Web Security Service Connector.
  • New Group—Type the name of the new group. Use alphanumeric characters only; do not use special characters. To add users to this group later, you can go to CONFIGURATION > Group Management and add users to the group.
  • Existing Group—Click in the text box to search for a group. Type the first three letters of the group you want to find, and then click on the Group name to select it.
  • IP Addresses—Type the IP address or subnet and two-digit CIDR prefix length. For multiple entries, click Add IP.
  • To create a rule for an individual user, either create a group specifically for that user or (if the user has a static IP address) use their IP address.

In the Threat Prevention area, select threat categories you want to include in this rule:

  • Anti-malware
  • Anti-virus
  • Purewire Intelligence
  • WebDAV/DLL Exploit

There are two ways an Administrator can override a block of a URL that is included as a Malicious Site in Rules > Threat Prevention > Purewire Intelligence area. Edit the rule and either:

  • Press the Ctrl key and click on the Malicious Sites option to deselect it, or
  • Add the URL to the Whitelist in the Rules > Advanced > Exceptions area.
