Chapter 15: Ten Web Sites to Visit The reason I give 3 stars is just because this book does not a have a practical development on how a Firewall should be. There are many Firewalls types in the world and this one is just explain in Microsoft Windows based. Yes, This book is not for technical professionals, this book is made for IT managers without a necessity the whole nuts and bolts of a Firewalls. I prefer this best as a starting reading and if you're done with this, try to look 'Building Internet Firewalls, SE', 'Linux Firewall', 'Linux Firewall, SE', Hacking Exposed series to tighten up your firewalls.

Summary: Great overview with lots of details
Comment: I don't really like the Dummies title, but I have found that Dummies books are very often written for people like me, who don't consider themselves Dummies at all. I was hoping that this one would be an easy-to-read introduction to firewalls that also provided some useful information. I was not disappointed.
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.

Summary: Clear, Economical, and Accesible Information on Firewalls
Comment: The authors and the technical editor of this book have done a superb job of making the complex subject of firewalls accessible to a wide audience. Regardless of your level of experience, you will be able to take something of value away from this book, whether it is a basic understanding of firewalls or some deeper insights into the complexities of NAT, IPSec, VPNs, and Kerberos. From setting up a personal firewall, such as Zone Alarm, to setting up multiple industrial-strength firewalls involvings DMZs, you will find a lot of good information and advice.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.
