Summary: a must read
Review: A long awaited 'definitive' Cisco Press book on Managing Security within corporate networks. Makes excellent read both for the simple and technical minds. If you thinking of the MCNS Exam this is it!!

Summary: Must-have for Cisco Security
Review: As I am currently working on my Cisco Security Specialization (CSS) I have read all books related to CSS. Out of the four books this is definately one of the most valuable references when it comes to Cisco network security. This book is well-structured, referencing all the potential threats and countermeasures that exist to network security. I really praise the author for his clear explaination of IPSec and PIX concepts. For those seeking to pass the MCNS 2.0 exam, this is a great reference and study guide. All necessary topics are covered, except the Cisco VPN Client, which has been added to the MCNS exam during version 2.0. Overall, a great book by a great author, a definite must-have for the future CSS1, CCIP/CCIE security specialists.

Summary: Good overview of Cisco security
Review: As mentioned by another reader, this book will not cover cryptographic mechanisms in details.
But it will give you an overview of everything you can do with Cisco products (relating to security), how to do it and where to find more information.
I read all Cisco books about security and this one is the more complete.
If you need to understand cryptography, you need books like Applied Cryptography.

Summary: I like!
Review: Cisco Press is funny because some of their books series are error-few and others are error-some. I really liked the content of this book though. I reference it for specific subjects as much or more than any other good book I own. I wish that it would give better descriptions of more detail on some key commands and not just the cut and paste of the command in the description field. Other than that there is a broad range of decent security info.

Summary: Excellent coverage of the exam and a good reference as well.
Review: For those of you who work on the PIX Firewall from Cisco and need to be trained on the finer points of the application, you'll find this book is right up your alley. The author has put a great deal of effort in this manual and results give you the best possible book on the topic I have seen so far. In over 750 pages this manual is broken down into five parts, each building on the section before. The amount of information included is very detailed and well documented and I can see another volume of information on the horizon. In part 1 this is where you learn to set up the security policy dealing with threats, denial of service attacks and the hacking process. Also covered the security policies and securing the switches and routers. Part 2 moves to dial-up security with the use is Cisco's AAA security, PPP, CHAP, PAP, TACTAS+, ACS and Radius are the major topics covered. Showing the different ways to ensure the dial in accounts are the only things creating traffic that will enter into your network. In Part 3 the author shows that the secure internet connection is one of the most important parts of the network security scheme. Topics include the setting up of the DMZ, using and working with the bastion host, firewall with NAT and PAT, and the Cisco PIX Firewall. Part 4 is the PIX Firewall section where you learn about the configuration of the PIX firewall, configuring multiple interfaces and AAA encryption. Finally part 5 which deals with VPN and IPSec. The author does ensure an understanding of IPSec, configuration and configuration with PIX rounds out the Section. Case studies are included, examples of the router code, an abundance of other examples and well as hands on tasks makes this a must have for everyone network manager, administrator and security specialist.

Summary: Excelent Book
Review: It doesn't get five starts because it lacks information about Intrusion Detection, which is an important part of Network Security. The rest of the book is excellent, not only for the CSS1 & CCIP certification (it can be a guide for the 640-442 MCNS, 9E0-571 CSPFA & 9E0-570 CSVPN (you need additional info on the VPN 3000 and the CS VPN Client for this exam)) but also as a reference book for implementing security on Cisco Networks.

Summary: So terribly disappointing
Review: May I just say how disappointed I was with this book.With the credentials of the author I was really looking forward to actually having a very very good 'understanding" of security .. and sadly all I got was a half baked coverage of core topics and a fairly well documented 'command-reference' guide to implement Cisco Security !! (I could have got that from the Cisco Documentation) What I was looking for was an in-depth understanding of the technology..didnt find it here and found the Cisco CCO Web site as a very very good reference and may I say a lot easier to read and understand !! For a hands-on aid in the lab - Mike's book I guess meets the requirement ... but thats not why one buys it in the first place !!

Summary: Most errors ever published in a book
Review: They should contact Guinness on this one. Almost every page has some type of error. (Mislabeled IP addresses, mistyped configs, etc.) It's amazing! Seriously though, the content in the book is good. However, the number of errors is bad. If there weren't any errors, I would have given it a 5.
