Firewall Protection and Content Filtering
4-21
v1.0, March 2009
Several types of blocking are available:
Web Components
blocking. You can block the following Web component types: Proxy, Java,
ActiveX, and Cookies. Even sites on the Trusted Domains list will be subject to Web
Components blocking when the blocking of a particular Web component is enabled.
Keyword
(and domain name) blocking. You can specify up to 32 words that, should they
appear in the Web site name (URL) or in a newsgroup name, will cause that site or newsgroup
to be blocked by the VPN firewall.
You can apply the keywords to one or more groups. Requests from the PCs in the groups for
which keyword blocking has been enabled will be blocked. Blocking does not occur for the
PCs that are in the groups for which keyword blocking has not been enabled.
You can bypass Keyword blocking for trusted domains by adding the exact matching domain
to the list of Trusted Domains. Access to the domains or keywords on this list by PCs, even
those in the groups for which keyword blocking has been enabled, will still be allowed without
any blocking.
Keyword Blocking application examples:
If the keyword “XXX” is specified, the URL <http://www.badstuff.com/xxx.html> is blocked,
as is the newsgroup alt.pictures.XXX.
If the keyword “.com” is specified, only Web sites with other domain suffixes (such as .edu
or.gov) can be viewed.
