Chapter 3: Getting Started
What about Security
Having a high-speed, always-on connection to the Internet requires a certain amount of
responsibility to other Internet users—including the need to maintain a reasonably secure
system. While no system is 100% secure, you can use the following tips to enhance your
system’s security:

Keep the operating system of your computer updated with the latest security patches.
Run the system update utility at least weekly.

Keep your email program updated with the latest security patches. In addition, avoid
opening email containing attachments, or opening files sent through chat rooms,
whenever possible.

Install a virus checker and keep it updated.

Avoid providing web or file-sharing services over your Telephony Gateway. Besides
certain vulnerability problems, most cable companies prohibit running servers on
consumer-level accounts and may suspend your account for violating your terms of
service.

Use the cable company’s mail servers for sending email.

Avoid using proxy software unless you are certain that it is not open for abuse by other
Internet users (some are shipped open by default). Criminals can take advantage of
open proxies to hide their identity when breaking into other computers or sending
spam. If you have an open proxy, your cable company may suspend your account to
protect the rest of the network.

The TG2472 ships with wireless LAN security set by default (for the same reasons that
you should run only secured proxies). See the security label on your product for the
factory security settings. If you need to modify the default wireless security settings, see
Configuring Your Wireless Connection.
Ethernet or Wireless?
There are two ways to connect your computer (or other equipment) to the Telephony
Gateway. The following will help you decide which is best for you:
Ethernet
Ethernet is a standard method of connecting two or more computers into a Local Area
Network (LAN). You can use the Ethernet connection if your computer has built-in
Ethernet hardware.
Note: To connect more than four computers to the TG2472 through the Ethernet ports, you
need an Ethernet hub (available at computer retailers).
