Amazon.com Review
With more and more small-office and home computers being left connected to the Internet at all times, the owners of those machines are being faced with problems that used to confront only big operations. The authors of Firewalls for Dummies spread the message: everyone with a cable modem, data satellite dish, or DSL connection needs a firewall now. Thankfully, though, these guys go beyond merely showing how to set up turnkey personal firewall products--too many Dummies books explain the obvious and the generally intuitive--and reveal how to set up the sorts of firewalls that protect sizable networks. By understanding these techniques, small operators can plan for growth and improve their level of protection. What's more, this book provides a serious explanation of corporate firewall products and techniques that's appropriate for people who build and maintain big systems.

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.

Customer Reviews

Great overview with lots of details
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.

Clear, Economical, and Accesible Information on Firewalls
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.

Trully for Dummies
I like the 'for Dummies' editions since I was reading Internet for Dummies. It has a humble explanation to present things in very unique approach. Clear and easy to understand, just like telling you what a heaven look like in human language.

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.
