WebBlocker Content
CHAPTER 4
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.
Alcohol/Tobacco
Pictures or text advocating the sale, consumption, or production of alcoholic
beverages and tobacco products.
Illegal Gambling
Pictures or text advocating materials or activities of a dubious nature that may
be illegal in any or all jurisdictions, such as illegal business schemes, chain
letters, copyright infringement, computer hacking, phreaking (using
someone's phone lines without permission), and software piracy. Also
includes text advocating gambling relating to lotteries, casinos, betting,
numbers games, online sports, or financial betting, including non-monetary
dares.
Reference Guide
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.
