Your first reaction is probably to put every client and server behind it. That's fine for a small company, but a larger company should consider creating a perimeter security network called a demilitarized zone (DMZ) that separates the internal network from the outside world. DMZs are the best place for your public information. That way customers, potential customers, and outsiders can obtain the information that they need about your company without accessing the internal network. Your confidential and proprietary company information should be stored behind your DMZ on your internal network. Servers on the DMZ shouldn't contain sensitive trade secrets, source code, or proprietary information. A breach of your DMZ servers should at worst create an annoyance in the form of downtime while you recover from the security breach.

This chapter describes a variety of ways to put firewall components together, and discusses their advantages and disadvantages. We'll tell you what some appropriate uses are for each architecture. The simplest firewall architectures have a single object that acts as the firewall. In general, the security advantage of single-box architectures is that they provide a single place that you can concentrate on and be sure that you have correctly configured, while the disadvantage is that your security is entirely dependent on a single place. There is no defense in depth, but on the other hand, you know exactly what your weakest link is and how weak it is, which is much harder with multiple layers.
