Product Description

Amazon 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 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.

Format: Paperback
This is the book for those with some computer knowledge. It is full of useful information but you need to be willing to plough through lots and lots of technospeak. It is not for the faint hearted either as it tells you what can happen if you are not protected against hackers. It does, however, tell you what to do.
Much better than Networking for Dummies!

Great overview with lots of details 24 Oct. 2001
By "lmcmc" - Published on
Format: Paperback
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 24 Oct. 2001
By Martin Grasdal - Published on
Format: Paperback
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.

A decent introduction. 5 Dec. 2007
By Mathew A. Shember - Published on
Format: Paperback
I picked this up for a curiosity check for some people that are getting interested in the security world.

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.

Trully for Dummies 26 Mar. 2002
By David Sudjiman - Published on
Format: Paperback
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.
This book contains very basic information that might help to anyone who has no idea what a firewall is. Very good explanation!
Here are the Content that will show you about the prefect dummies explanation.

Chapter 6: Developing Policies
Chapter 7: Establishing rules for Simple Protocols
Chapter 8: Designing Advanced Protocol Rules

Chapter 13: Choosing a Firewall That Meets Your Needs
Part 5: The Part of Tens
Chapter 14: Ten Tools You Can't Do Without
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.

"firewalls" misleading ... content is general internet security 1 Jun. 2009
By Fernando Ortiz - Published on
Format: Paperback
The title "Firewalls for dummies" is misleading. No, it does not talk to the layperson, or even someone trying to setup a home firewall. Rather, it targets manager-types at companies that have basic tcp/ip experience. The first 150 pages or so doesn't even have any solid examples of allow/deny rules. There is another book called "internet security for dummies". This should have probably been that book, because the depth it goes into general security issues like antivirus, file attachements, mail security is much more general than firewalls. Plus I think I see a few errors in the book and am unable to locate an errata for it online. I wrote to the FirewallsForDummies[at] address thats mentioned in the book to ask the authors for errata info, and it bounced back as mailbox not available.
