"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).
Most Helpful Customer Reviews
As commercial websites and networks get built out, some companies find that their network becomes the nervous system of the organisation. The ubiquity of email and browsing, and the storage of much corporate information on a network, has led to a vital need to defend it. The good news, in part, as pointed out by Bejtlich, is that you, the sysadmin, have available a very powerful set of free, open source tools, to scrutinise the network for anomalies. Tcpdump, Tethereal, Ethereal, Snort, Editcap, Mergecop, Tcpslice, etc. All free and supported by communities of developers. But these are not trivial to use. For example, Ethereal and Snort each have entire books devoted to them. Not surprisingly then, a large portion of this book discusses using the many tools. You do not necessarily need to use all of them. But as a sysadmin, you need to be generally aware of the different capabilities of the major tools, and how to best use them. Some explanations also include screen captures from their UIs, to give you a better idea of their operation. But the book is more than just a collection of tool explanations. Bejtlich also promotes an overarching coherent approach to network security monitoring, that rises above the operational details of any tool. Much more qualitative than the specific details of using a given tool. But ultimately, this approach may be the most enduring value of the book.
