Creating Rules for the Barracuda Web Security Service

  • Last updated on

This documentation applies to the Barracuda Web Security Service sold prior to April 1, 2017. As of this date, the service is still maintained, while new customers can purchase the new Barracuda Web Security Service cloud based solution powered by Zscaler, the leading cloud web security solution for enterprises. Click here for documentation on the new Barracuda Web Security Service.

Rules let you monitor or control how clients interact with the web. You define rules indicating which sites are allowed or disallowed based on content or malware risk, then specify the response to user web requests violating the rule.  For each rule, you can create enforcement schedules and throttle web use by limiting connections, bytes, or time. There are two types of rules:

  • Global Only
  • Group or User-based

Global rules apply one set of rules to everyone. Group or User-based rules apply to different groups of people or even to individual users. To configure Group or User-based rules, you need to configure authentication. Refer to How to Configure Authentication, or if you are deploying a Barracuda Web Security Service Connector, refer to Authentication with the Barracuda Web Security Service Connector.

Order of Execution within Rules

Blocking or Allowing Access within a Rule

The Purewire Intelligence WebDAV/DLL Hijack Rule Option

Allowing or Blocking Specific Objects on a Website

Enforcing Schedules and Quotas

Actions Taken for Traffic Matching the Rule

After You Add or Change Rules

After you add or change rules, web browser cache and caching servers may have content stored locally that makes a rule appear to be working improperly. If this occurs, then the web browser cache should be cleared manually and the cache should be cleared on caching servers.
