Network Security

Now that you have a LANeven if it's just a simple peer-to-peer LANyou should be worried about network security and hackers. Why? Because you'll certainly be connecting to the Internet, even if only intermittently, and when you do, you risk exposing your network to the entire world. These risks are not as far-fetched as you might think.

Refer to Chapter 21, "Network Security," to find out what risks you'll be exposed to and what you can do to protect your LAN. If you use Internet Connection Sharing or a connection sharing router, you're in pretty good shape, but in any case please go through Chapter 21 very carefully. It is very important.
