The authors generally steer away from showing how to configure specific firewall products, though a few of the biggies--Microsoft Internet Security and Acceleration Server, BlackICE, ZoneAlarm, and Check Point FireWall-1--get comparative overview coverage. Mostly, they favor more general firewall configuration strategies and techniques. These they explain with a lot of prose, a fair number of conceptual diagrams, and tables that sum up permission rules. This is a worthwhile read. --David Wall
Topics covered: Firewalls and the ways they can be deployed to prevent unauthorized access to computers and networks without interfering with the protected users' ability to get out to the Internet. A summary of networking fundamentals as they apply to firewalls is followed by coverage of network address translation (NAT), demilitarized zones (DMZs) as created by multiple or even single computers, and filtering policies.
