Advanced Policy Creation

Because different rules may apply to different constituencies in your organisation, the Barracuda Web Filter supports extremely granular applications of policies by user, group, or IP address range.  It also supports time-based policies.  Features include:

  • Default guest and user policies.  For rapid deployment, the Barracuda Web Filter comes preconfigured with default guest (unauthenticated user) and known user (authenticated user) policies.  You can easily customise default policies for content filtering and application blocking with simple easy-to-use Web forms.
  • User and group policy exceptions.  You can customise policies by defining exceptions on top of the default policies.  Policy exceptions can apply to content filtering and application blocking rules, and they can apply to specific users, groups, or network IP address ranges.  For example, you can set a default policy to block Web access to job sites but create an exception for the Human Resources group to allow them.
  • Integration with LDAP directory servers.  The Barracuda Web Filter integrates with popular LDAP directory servers, including Microsoft Active Directory, IBM Lotus Domino Directory, and Novell eDirectory.  This integration provides the Barracuda Web Filter with real-time access to user and group membership managed by the directory server.  You can define policies that apply to LDAP users and groups.
  • Integration with Windows Domain Controllers.   Included with the Barracuda Web Filter is the Barracuda DC Agent, software that can be installed on your Windows Domain Controller.  This software provides the Barracuda Web Filter with the username logged at each IP address, and it enables proper application of policy without requiring any user intervention and without a separate login.
  • Local users and groups.  For sites that do not use directory servers or who wish to define policies for users and groups not managed by the directory server, the Barracuda Web Filter supports the creation of local users and groups on which to apply policy.
  • Network IP address groups.  You can define policies that only apply to certain network IP address ranges or subnets.
  • Warning policies. The Barracuda Web Filter enables you to define policies for Web access that present users with a block page but allow them to proceed after being warned. Warning policies are useful for reminding users about sites which may violate corporate Internet usage policy without blocking them outright.
  • Web traffic monitoring. You can define policies for monitoring specific Web site categories, domain names, or URL patterns without presenting block pages to users or preventing access. Monitoring is useful to assess the potential impact of new policies prior to implementing access restrictions on the user community.
  • Time-based policy exceptions.  You can define policy exceptions for both content filtering and application blocking based on time-of-day.  For example, you can set a default policy to block access to sports sites but to allow browsing during non-working hours.

The Barracuda Web Filter was designed with ease of deployment in mind.  With default policies, even organisations new to Web filtering can get started quickly.  Organisations with more advanced filtering requirements can take advantage of advanced policy exceptions and integration with enterprise infrastructure.

Internet Application Blocking

Unlike pure HTTP proxy solutions, the Barracuda Web Filter also enables you to enforce policies governing usage of applications that access the Internet.  Features include:

  • Instant Messaging (IM) Blocking.  The Barracuda Web Filter enables you to set policy governing usage of public IM clients, including AIM, ICQ, Yahoo! Messenger, and MSN Messenger, and ICQ.   These public IM clients can not only provide means for unmonitored communications, but their security vulnerabilities are often the target of those in the hacking community.  Blocking public IM communications outright is one strategy to secure information flow and increase network security.
  • Application Blocking.  In addition to IM applications, the Barracuda Web Filter includes policies for popular applications that access the Internet, including Internet music applications, software updaters, and popular browser toolbars.
  • IP and Port Blocking.  You can customise your own IP blocking policies based on any combination of source or destination network IP address ranges and ports.  One common usage of this feature is to prevent compromised machines from accessing the Internet.

The combination of Web and other Internet application blocking techniques enables you to define and implement complete Internet usage policies for your organisation.
