Product Description
Amazon.co.uk Review
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 favour 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 unauthorised 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), Demilitarised Zones (DMZs) as created by multiple or even single computers, and filtering policies. --This text refers to an out of print or unavailable edition of this title.

Much better than Networking for Dummies!
Like other Dummies books, this one is very easy to approach, but it went far beyond that. I started reading this book because I wanted to get a good basic background in what firewalls are. The first few chapters did accomplish this. They also got me to think about quite a few computer security issues I had not even considered before. I especially liked that it helped me with setting up a personal firewall. At the same tiem I know that I can get back to the chapters on other, more powerful firewalls in the future. What surprised me about this book was the level of detail it went into in the chapters on how to configure a firewall for complex scenarios, such as VPN solutions. I actually also learned a lot about other, related computer security issues. Right now I don't need all of this information, but it is good to have a book that has information that I will fins useful in the months or even years to come. Many Dummies books are very approachable, and this one os no exception. However, I found that this one didn't stop at the basics. Rather, it went into topics should be useful even for someone who has to set up and configure a firewall in a medium-sized organization.
The authors show a concern for crafting clear, economical, and easy-to-understand explanations of otherwise difficult concepts. Their experience as consultants and educators is obvious. You could buy more expensive and abstruse books on firewalls, but you probably won't enjoy them as much and you probably won't get as much out of them. The authors have done a great job.
As with the Dummies line, this book is meant as an introduction to the concept of a firewall.
If you ever asked "What's a firewall" then this book is for you. If you are looking for specific configurations or what to do when you are under attack, you will not like this book.
I gave it high marks because it discusses many concepts such as caching, stateful inspection, load balancing, protocols, etc. However, it does not go heavily into the technical which could make a non-IT person go comatose.
There are some discussion of attacks such as Denial of Service, Trojans, etc. but they are rather basic in nature. Again not a book for the advanced.
There is a decent discussion on policies and a reasonable discussion on NAT, that should give the inexperienced a good idea of these areas.
There are some discussions on deployment which the book might have been trying to reach the corporate environment. However, the value maybe only for managers who would not be involved with the firewall or they simply could have been left out. The book mainly feels for the small networks and the home user and probably would not care about three pronged firewalls.
The chapter on Linux firewalls talking about iptables and ipchains felt like it was an addon due to the rise of Linux. Having said that; it still was a decent introduction. It just felt out of place.
The chapters on Zonealarm, BlackIce, Norton, ISA, and Checkpoint are useful to a degree. They do discuss the products and they go into setup. However, you will probably read the information parts but probably will end up skipping the configuration sections.
The last two chapters are useful as they give you websites for 10 tools(though a couple have changed) and sites to find information about Firewalls and security groups.
Overall, it's a decent book for the beginner. Avoidable for the professional.
