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).
