In this introduction to protecting your computers from intrusion, the author discusses concepts of computer security. Selecting good passwords, using firewalls, and other security concepts are introduced. If your computer is not connected to any other computers and doesn't have a modem, the only way anyone can access your computer's information is by physically coming to the computer and sitting at it. So securing the room it's in will secure the computer[1]. As soon as your computer is connected to another computer you add the possibility that someone using the other computer can access your computer's information.

If your network (your connected computers) consists only of other computers in the same building you can still secure the network by securing the rooms the computers are in. An example of this would be two computers sharing the same files and printer, but not having a modem and not being connected to any other computers.

However, it's wise to learn about other ways to secure a network of connected computers, in case you add something later. Networks have a tendency to grow. If you have a network, an intruder who gains access to one computer has at least some access to all of them.
