Amazon.com Review Internet Firewalls and Network Security succeeds precisely because of its restricted focus: half of this book is devoted to firewalls and packet filters. After a comprehensive introduction to the architecture and theory of firewalls, the guide documents several commercial and noncommercial packages, including a shareware product included on the bundled CD-ROM. One of the book's highlights is a fine chapter on defining a network policy. Coauthor Chris Hare is a contributor to SysAdmin magazine, and it shows. This section feels like it was written for real-world network administrators, whether beginning or experienced. There are some weaker points, including an introduction to TCP/IP and Unix basics with too many details for the beginner and too few for the expert. But these flaws are more than offset by the depth of information you'll find on the book's core subjects. *** The information presented in Part I provides an overview of security and TCP/IP. Being the protocol of the Internet, it is important to understand how TCP/IP works and what utilities are available. It also is important to understand the concept of security and why it is necessary to limit access to resources. Part II covers firewalls and screening routers. Not only are various theories and hypothetical examples discussed, but real-world examples are given. Over-the-counter products are discussed, as well as tool kits that enable you to build your own firewall from scratch. Part III, the appendix section, offers a quick way to locate key information. Appendix A lists the sample worksheets contained in the chapters and where they can be found. Appendix B lists sources of more information. Appendix C provides a list of vendors. Appendix D provides the manual pages for OPIE and Log Daemon, two forms of the one-time password authentication system. PassWord: No
