Internet Security And The Firewall - Toshiba Magnia SG20 User Manual

Establishing an Internet Connection
To add a new keyword to use for blocking, type it in the fields at the bottom of the screen.
After typing the keyword, click Add, to include it in the list of keywords.
If you add a keyword to the list and wish to remove it later, come to this screen, select the
keyword and click Remove. The keyword is removed from the list and is no longer used
to block or filter URLs.
Note that use of filtering keywords can have the effect of blocking sites or URLs
unintentionally. For example, the keyword "sex" would block sites such as
, or URLs such as /
www.essex.com
URLs may be generated automatically by some Web sites. As a result, keyword blocking
may filter access in unintended ways, and should be used with caution.

Internet security and the firewall

The Magnia SG20 serves as a gateway between your local network (LAN) and the
Internet. Whether through a broadband connection using the built-in Ethernet port, or
through the built-in modem connection for dial-up Internet access, all your local network's
traffic for the Internet is channeled through the server's gateway. This provides much
more efficient access to the Internet.
Firewall security
The Magnia SG20 incorporates a firewall into the Internet gateway feature to prevent
unauthorized access to your network.
DEFINITION: Firewall is the term for a security measure implemented in both
hardware and software that prohibits unauthorized users on the Internet from
gaining access to the resources on your network.
This firewall is designed to protect your local network while allowing efficient access to
the Internet for your users. It prohibits access to your local computer network, and
protects your proprietary data and files.
