From the Back Cover
"The book you are about to read will arm you with the knowledge you need to defend your network from attackers-both the obvious and the not so obvious.... If you are new to network security, don't put this book back on the shelf! This is a great book for beginners and I wish I had access to it many years ago. If you've learned the basics of TCP/IP protocols and run an open source or commercial IDS, you may be asking 'What's next?' If so, this book is for you."
-Ron Gula, founder and CTO, Tenable Network Security, from the Foreword
"Richard Bejtlich has a good perspective on Internet security-one that is orderly and practical at the same time. He keeps readers grounded and addresses the fundamentals in an accessible way."
-Marcus Ranum, TruSecure
"This book is not about security or network monitoring: It's about both, and in reality these are two aspects of the same problem. You can easily find people who are security experts or network monitors, but this book explains how to master both topics."
-Luca Deri, ntop.org
"This book will enable security professionals of all skill sets to improve their understanding of what it takes to set up, maintain, and utilize a successful network intrusion detection strategy." -Kirby Kuehl, Cisco Systems
Every network can be compromised. There are too many systems, offering too many services, running too many flawed applications. No amount of careful coding, patch management, or access control can keep out every attacker. If prevention eventually fails, how do you prepare for the intrusions that will eventually happen?
Network security monitoring (NSM) equips security staff to deal with the inevitable consequences of too few resources and too many responsibilities. NSM collects the data needed to generate better assessment, detection, and response processes-resulting in decreased impact from unauthorized activities.
In "The Tao of Network Security Monitoring," Richard Bejtlich explores the products, people, and processes that implement the NSM model. By focusing on case studies and the application of open source tools, he helps you gain hands-on knowledge of how to better defend networks and how to mitigate damage from security incidents.
Inside, you will find in-depth information on the following areas. The NSM operational framework and deployment considerations. How to use a variety of open-source tools-including Sguil, Argus, and Ethereal-to mine network traffic for full content, session, statistical, and alert data.Best practices for conducting emergency NSM in an incident response scenario, evaluating monitoring vendors, and deploying an NSM architecture.Developing and applying knowledge of weapons, tactics, telecommunications, system administration, scripting, and programming for NSM.The best tools for generating arbitrary packets, exploiting flaws, manipulating traffic, and conducting reconnaissance.
Whether you are new to network intrusion detection and incident response, or a computer-security veteran, this book will enable you to quickly develop and apply the skills needed to detect, prevent, and respond to new and emerging threats.
About the Author
Richard Bejtlich is founder of TaoSecurity, a company that helps clients detect, contain, and remediate intrusions using Network Security Monitoring (NSM) principles. He was formerly a principal consultant at Foundstone--performing incident response, emergency NSM, and security research and training--and created NSM operations for ManTech International Corporation and Ball Aerospace & Technologies Corporation. For three years, Bejtlich defended U.S. information assets as a captain in the Air Force Computer Emergency Response Team (AFCERT). Formally trained as an intelligence officer, he is a graduate of Harvard University and of the U.S. Air Force Academy. He has authored or coauthored several security books, including The Tao of Network Security Monitoring (Addison-Wesley, 2004).

However against the odds I must admit Richard succeeded in this new role, and wrote a very good book. Perhaps a bit overcharged of dumps. . . but useful and representative ones.
Tired of too much theory and so little practice?. . . then just buy this book and hands at work.
I got dozens of security books (I do my living as security specialist) and am every time more careful when buying or recommending books. This one deserves to be in every specialist shelf.
I am relatively new to the network security field, and I can say that this book is really worth it. It explained things better than the required text. I defenately recommend it.
"The best reference for building an NSM infrastructure is my book, The Tao of Network Security
Monitoring: Beyond Intrusion Detection". So far that statement is indisputable. This is a whopping
and very detailed 800+ page text on NSM that pushes "on-shelf" technical literature to a new level of
scholarship. The book is heavily foot noted with academic research and includes a history of NSM.
I was fortunate enough to receive this book in a college course on network security. In my opinion
it was the single best book I received out of my 4 year study. I've read it 2 times, cover to cover, and
continually use it as a reference. By applying the techniques and principles in the book I was able
to gain an entirely new perspective on network connections; I also increased my knowledge of TCP/IP
substantially by practicing the examples at home. I've only been out of college for a little over a year
now and I've been able to perform NSM duties in my day job and have spoken on traffic analysis at some
small conferences. This book has been a great benefactor towards my professional development as it has
provided new avenues of interest for me to explore.
Session data, statistical data, and full-content data concepts are each covered thoroughly with many
examples of popular and not-so popular FOSS (Free and Open Source Software) tools. As I mentioned in my
recent review of Extrusion Detection, I really enjoy the fact that the author exposes readers to FreeBSD
by using it as his platform throughout the book.
There's no need to summarize what's in the book as you can view its table of contents here on
I recommend this book, not just for security folk, but also for network folk who I believe can advance
with a new perspective on network traffic and gain a deeper understanding of their environments.
I came with knowledge of tcpdump, I left knowing how to use it.
At first, the author's tone put me off. He spends the introductory chapters talking about the "Way" of Network Security Monitoring, (capitalized) and how it's much better than other approaches. It felt a little like, "My Burping Crane Kung-Fu will defeat your Shining Fist techniques!" I really didn't see much difference between what he was talking about and other approaches. I admit to being much newer to this discipline than the author, and he has an impressive appendix on the intellectual history of intrusion detection (uncapitalized). So it may be that the lessons he advocates have already been internalized; my exposure may have been to a field that has already moved up to his standard. But I have a hard time imagining that intrusion analysts have ever been satisfied with a single approach with no correlation. As I understand what he means by upper-case NSM, it's basically the efficient use of multiple techniques to detect intrusions. I can't see trying to argue the contrary position.
Ah, but then we get to the good stuff. He goes through the major types of indicators and the means of reviewing them. He covers the use of a number of important tools, but doesn't rehash what is better covered elsewhere. For example, he doesn't bother covering Snort, because there are plenty of books on Snort already. If you are reading the book, it's almost a certainty that you are familiar with Snort. Good call to skip over that. Instead, he covers some other tools that might be useful in the same area. He also refers to tons of other books. I made a lengthy wish-list based on his recommendations and they've been good. (He also reviews exhaustively here on Amazon). So this book is like the first stone in an avalanche- it triggers the acquisition of many other books.
The book provided many 'light bulb' moments. For example, he talks about giving up on source-based focus. In a world where a DDoS attack is currently using 23,000 separate bots, we may exhaust our resources tracking low-value drones. So focus on the targets they are after: light-bulb! In spite of my earlier resistance, I was soon going through it as eagerly as I did with the Patrick O'Brian Aubrey/Maturin novels. It's fun to read such clear, authoritative writing.
One quibble - he trashes the SANS intrusion detection course, which I took and thought was terrific. He has taught the class, and considered the course material out of date. Maybe they have updated, but his book didn't contradict anything in the course as I took it 1.5 years ago.
