CHAPTER 7 WebBlocker Content
WebBlocker works in conjunction with the HTTP proxy to provide
content-based URL-filtering capabilities.
WebBlocker Categories
WebBlocker relies on a URL database built and maintained by
SurfControl. The Firebox automatically and regularly downloads a
current version of the WebBlocker database from the WatchGuard Web
site to your log host. The Firebox then copies the new version into
memory. This process ensures the most up-to-date Web filtering and
blocking capabilities.
SurfControl constantly searches the Internet to update the list of blocked
sites. The WebBlocker database contains the following 14 categories.
N OTE
In all of the categories, sites to be blocked are selected by advocacy rather
than opinion or educational material. For example, the Drugs/Drug
Culture category blocks sites describing how to grow and use marijuana
but does not block sites discussing the historical use of marijuana.
