More than a million systems are now connected to the Internet, and something like 15 million people in 100 countries on all seven continents use Internet services. More than 100 million email messages are exchanged each day, along with countless files, documents, and audio and video images. Although businesses are rushing headlong to get connected to the Internet, the security risks have never been greater. Some of these risks have been around since the early days of networking -- password attacks (guessing them or cracking them via password dictionaries and cracking programs), denial of service, and exploiting known security holes. Some risks are newer and even more dangerous -- packet sniffers, IP (Internet Protocol) forgery, and various types of hijacking. Firewalls are a very effective way to protect your system from these Internet security threats. Building Internet Firewalls is a practical guide to building firewalls on the Internet. If your site is connected to the Internet, or if you're considering getting connected, you need this book. It describes a variety of firewall approaches and architectures and discusses how you can build packet filtering and proxying solutions at your site. It also contains a full discussion of how to configure Internet services (e.g., FTP, SMTP, Telnet) to work with a firewall, as well as a complete list of resources, including the location of many publicly available firewall construction tools.
