Media praise for Security Warrior

"A very well written, comprehensive text that contains useful references, and details of software tools (and where they can be found). An essential resource for those responsible for information security."
--Major Keary, "PC Update," October 2004

"As in the case in the physical world, when providing computer security the optimal approach is to be proactive. Security Warrior is about taking such a preventive approach to computer predators...The vulnerabilities are clearly defined, but the book really shines when it provides detailed instructions on how systems can be protected. Security Warrior is written for advanced system administrators charged with network or system security. Corporate security professionals may be intimidated by the book, but they would do well to get a copy to the appropriate person in their organizations. That would be the proactive thing to do."
--Ben Rothke, Security Management, January 2005

"Overall, Security Warrior was quite an interesting read. I fully plan to take many concepts I have learned here and incorporate them into both current and future plans. If you want a detailed look at network security concepts, this book is a very solid starting point, before branching out into other works."
--Sean Smith, Dalhousie Student Chapter ACM, July 2005

"Given that hundreds of security books are out there, I was a bit skeptical this one would live up to its claim of being so different. However, as soon as you enter the first section, 'Software Cracking,' you know you are in for a different ride...Overall, I found this book to be a strong text with a refreshingly different spin on computer/network security. If you are responsible for system or network security, Security Warrior is definitely worth reading."
--Dan York, Linux Journal, October 2004

"['Security Warrior' gives you] lots of code examples to work with, and no patronizing along the way...Sure, you can do what the hackers do, and trawl the dodgy hacking we sites and chat rooms to get this information, but why bother when for less than £25 [$44.95 US] you get it all in one reference..."
Rating: 9/10
--PC Plus, Spring 2004

"Security Warrior is the most comprehensive, up-to-date book covering the art of computer war: attacks against computer systems and their defenses. It's often scary, and never comforting. If you are on the front lines of computer network defense, defending your site against attackers, you need this book...These authors have produced a significant contribution to the rapidly growing number of titles in the specialized genre of computer security. Even though there are many other similar titles, this O'Reilly title is superior to most and I strongly recommend all network administrators get a copy of this powerful title, and to also consider multiple copies for loaning to other computer network support staff."
--Dale Farris, Golden Triangle PC Club, May 2004

"'Security Warrior' is a book that you will dog-ear and sticky-note like crazy, and keep pulling it off the shelf every time you embark on a new security project or do a job for a new client. If I had to describe 'Security Warrior' in one word, it would be 'toolkit.'"
--Brian Keefer, San Francisco OpenBSD Users Group, April 2004

"This is one of the few books that goes beyond the 'what' and deals with the 'how' of system and software security. A thorough reading and study of this book will arm you with the tools and knowledge you need to analyze and bight back against software attacks."
--Portland Domino/Notes User Group (PDNUG), March 2004

"Peikari and Chuvakin have written a valuable book that will soon find its way onto the shelf of everyone involved in network and machine security."
Peter Salus,, March 2004

"This book will help if you want to know enough about IT security to claim to be a know-it-all."
--Vince Tuesday, ComputerWorld, February 2004

"['Security Warrior' is] a great collection of tricks that should be part of a good warrior's training."
--Peter Wayner, Slashdot, March 2004

"This is a book with an amazing amount of information that at first glance may scare the living daylights out of some sys admins when they learn of the relative ease with which a system can be compromised. Then again, most security experts know of the risks and dangers involved with computer security. And I've always felt that to defend yourself against an attack, you should 'know the enemy.' This book offers lots of ways and 'tricks' to do just that."
--Todd Hawley,, February 2004

"If you want to know the latest about how black-hat hackers break into Windows, Linux, and even handheld operating systems such as Windows CE, then 'Security Warrior' is a read you need...For the true IT professional this is the kind of stuff that's essential to understand. Another security classic from O'Reilly Publishing."
--Brian Livingston,, February 2004
