To use keyword and domain blocking
Keyword and Domain blocking allows you to restrict access to Internet sites by
blocking access to those sites based on a word or a text string contained in the URLs
used to access those Internet sites.
Domain blocking allows you to restrict access to Websites based on the site's Domain
Name. The Domain Name is the portion of the URL that precedes the familiar .COM,
.ORG, or .GOV extension.
Keyword blocking allows you to block access to Internet sites based on a Keyword
or text string being present anywhere in the URL, not just in the Domain Name.
Note: The Domain blocking feature blocks access to any Domain in the Domain List.
It will also block Domains, any portion of which contains an exact match to entries in
the list.
For example, if you enter example.com as a Domain, any site that contains
―example.com‖ will be blocked. Generally, you do not want to include ―www.‖ in a
Domain Name since doing so limits the blocking to only the site that matches that
Domain Name exactly. For instance, if you enter www.example.com into the list,
only the one site that matches that name exactly will be blocked. Consequently, if
you do not include the ―www.,‖ then all sites within and associated with
―example.com‖ will be blocked.
Block Services
You can filter access to various applications accessed over the Internet, such as FTP
or telnet, by selecting up to two services to block in the Blocked Services section.
The Blocked Services drop-down menu offers a choice of preset applications. If you
select a preset application, its port numbers and protocol are displayed and cannot
be changed.
