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.

To some, a firewall is the alpha and omega of computing security. Running a computer to filter and protect your network will guard you from many dangers, they claim. To others, a firewall is just one more challenge to overcome in finding electronic jewels on servers and other machines in an organization. In two parts and several appendixes, Siyan and Hare examine the basic problems in networking and the specific means to filter traffic and deter security troubles. First, they discuss TCP/IP, networking, and network policy. Second, they examine screening routers and packet filters with plenty of helpful illustrations. While they do not offer detailed coverage of the broad range of topics found in Network Security because they tackle just one subset of the security spectrum, Siyan and Hare have done an admirable job in making that complicated topic understandable.
