Content Filtering
Overview

Web Content Filtering on the ProCurve Secure Router

7000dl Series

Web content filtering is the best way to minimize the problems associated with
misuse of the Internet at work. Web content filtering prevents undesirable
Internet activity while allowing mission-critical traffic and applications.
Firewalls and access control lists (ACLs) are valuable security tools, but they
are not designed to prevent legitimate users from accessing inappropriate
content. For example, ACLs filter packets based on information in the IP
header, which does not indicate whether a destination Web site is a legitimate
research tool, an online retailer, a personal blog, or a pornography site.
Web content filtering solutions, on the other hand, look at information inside
packets destined to the Internet—specifically, the URL of the Web site in
question. The solution then determines whether the user sending the traffic is
allowed to access that site, basing its decision on a database of URLs and a
configurable set of policies.
Integrating with Websense® Enterprise, the ProCurve Secure Router 7000dl
Series provides one piece of a Web content filtering solution. The ProCurve
Secure Router collects requests for access to external Web sites and submits
those requests to the Websense server, which makes the decision to allow or
deny access to the site in question. The Websense server can be located on
the same LAN as the ProCurve Secure Router or in another segment of the
WAN (for example, at a central office), making this solution for companies
with distributed offices.

The Role of the Websense Enterprise Solution

The ProCurve Secure Router's Web content filtering capabilities require your
network to have a Websense Security Suite (version 6.1.1 or later) that
includes Websense Enterprise. You actually create all filtering policies on the
Websense server.
An enterprise-level content filtering solution such as Websense can draw on
an extensive database of URLs that are classified according to content, making
it easy for you to create comprehensive security policies. For example, you
can configure the solution to prevent users from accessing gambling Web sites
without personally tracking down every such Web site. Websense handles
keeping the database up-to-date and accurate.
