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 SBV3202. 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 service provider’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 service provider may suspend your account to protect the

rest of the network.

Ethernet connection

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.
