This is well written and an explanation that is clear.
F. Loehmann
What this person should have read, in addition to that book, is Network Security Assessment (Chris McNab, O'Reilly Media, Inc., 2004, 371 Pages).
Christopher Byrne
This is an excellent written book that I would definitely recommend to anyone interested in Network Security.

Format: Paperback
"Network Security Assessment" (NSA) is the latest in a long line of vulnerability assessment / penetration testing books, stretching back to "Maximum Security" in 1997 and "Hacking Exposed" shortly thereafter. NSA is also the second major security title from O'Reilly this year, soon to be followed by "Network Security Hacks." NSA is a good book with some new material to offer, but don't expect to find deep security insight in this or similar assessment books.
NSA begins with the almost obligatory reference to the king of assessment books, "Hacking Exposed" (HE), saying "I leave listings of obscure techniques to behemoth 800-page 'hacking' books." I don't think some of the techniques covered in HE but not NSA are "obscure." Noticably lacking in NSA is coverage of dial-up techniques, wireless insecurities, Novell vulnerabilities, and attacking clients rather than servers. Should NSA receive a second edition, I expect to see the book expand closer to the "behemoth" it seems to deride.
The best chapter by far was ch. 11, where the author with assistance from Michael Thumann takes the reader on a tour of exploiting vulnerable code. The stack diagrams and code snippets were especially helpful and the explanations were clear enough. This sort of material is a solid introduction to some of the techniques found in "Security Warrior." I also liked ch. 14, where the author explains a sample assessment using the tools already introduced. Kudos as well for maintaining an errata page and tool archive on the publisher's Web site.
The advantage NSA has over HE is the variety of tools on hand. I learned of at least a dozen tools not mentioned elsewhere.

Format: Paperback
[A review of the 2nd EDITION. This review was written on 3 December 2007.]

Over 3 years has elapsed since McNab wrote his first edition. Much of that edition is still valid. Sadly, in a way, because it means that despite the best efforts of that book and others of its ilk, we remain plagued with network attackers and insecure systems.

One of the constants between the editions is the focus on IPv4. Still! IPv6 only gets a glancing mention in the second edition. While everyone recognises that IPv4 will get exhausted of addresses, the transition to v6 still gets postponed. McNab ruminates that this very transition will of its own accord generate compromises. I wish he'd expand on this remark. But maybe there is yet little market reason to do so.

Another thing that does not get mentioned is phishing. In early 2004, it was still a minor threat. It has since blossomed into a chronic problem. But McNab is correct to ignore it, up to a point. He believes, as apparently does most of the IT security field, that phishing is largely a social engineering problem. That it is not a technical problem of patching bugs, per se. Yet viewed properly, phishing is a network attack that uses social engineering, and it is amenable to technical countermeasures that involve, in part, network actions.

I especially favour this edition, for the reasons in the preceding paragraph. In 2004, I and a co-inventor, Marvin Shannon, devised a US Patent Pending against phishing. The second edition of McNab's book came out in November 2007, and by not discussing phishing, it buttresses our claims of non-obviousness, 3 years after our filing.

Format: Paperback
This book is a great resource for any administrator with IP networks to protect. As Wes Boudville says, it certainly is systematic with some great guidelines and useful checklists. The high level concepts laid out by the author make it much easier to understand the underlying issues with security nowadays. Instead of listing bugs and patches, McNab explains the different bug types, and I learnt a lot about stack and heap overflows in the application security chapter.
I'd recommend this book over Hacking Exposed and other books with the word 'hacking' in the title. The assessment material is comprehensive from both Unix and Windows standpoints, and I certainly picked up a bunch of new tricks that I wasn't aware of before. The book has great coverage of all the latest tools and techniques, but written in a timeless way. At just under 400 pages you'll find that it's not too long either!

The author has managed to pack a serious amount of low-level technical information into this book. In the other penetration testing and hacking books I've read, I haven't yet found one to be as comprehensive as Network Security Assessment--to give you an example this book covers IPsec, Citrix and Oracle issues that I have not seen covered elsewhere in print, let alone in the same book. A downside is that the book is hard to read from cover-to-cover, and should be used more as a reference, and the author does assume a level of reader knowledge. I've just finished reading Shellcoder's Handbook too, and found chapter 13 of this book to be a great technical primer for application level issues (such as heap, stack, integer overflows and format string bugs)--the diagrams are excellent and easy for anyone to understand.
All in all this is a very useful book for both the professional security analyst and systems admin with large networks to protect. The Oreilly site has some good info that you should check out, such as the TOC, index and sample chapter on network scanning ([...]
