Book Description
"The book you are about to read will arm you with the knowledge you need to defend your network from attackersboth 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 securityone 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 processesresulting 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 toolsincluding Sguil, Argus, and Etherealto 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.

Customer Reviews & Comments
Here is a really cool security book, that made me lose half a nigh sleep when I first got it. Richard Bejtlich "Tao of Network Security Monitoring" ("Tao of NSM") covers the process, tools and analysis techniques for monitoring your network using intrusion detection, session data, traffic statistical information and other data. Here are some of the book highlights. The book starts from a really exciting and fun background on security, risk and the need to monitor networks and systems. Topics such as the classic "threat x vulnerability x value = risk" formula to threat modeling and limitation of attack prevention technologies are included. A nice thing on the process side is the "assess -> protect -> detect -> respond" loop, that defines a security process for an organization on a high level. Threat analysis material seems to have military origin, but is enlightening for other types of organizations as well. NSM is introduced as being 'beyond IDS' with some coverage on why IDS deployments fail and what else is needed (NSM process and tools, that is). A great and rarely appreciated idea expressed in the book is that the intruders are often smarter than defenders. It presents a stark contrast to all this "staying ahead of the hackers", which makes no sense in many cases as the attackers are in fact far ahead. NSM approach will indeed work against the advanced attackers, albeit a high resource cost to the defending organization. Such 'worst case' scenario preparations are extremely rare in other security books. Detecting such intruder is covered during their five phases of compromise (from reconnaissance to using/abusing the system). Another gem is an idea of a "defensible network"; not 'secure' or 'protected', but defensible. 'Defensible network' can be watched, is configured to limit possible intruder actions, can be kept up to date and runs only the minimum necessary services, that assures that if bad things happen there, they can be handled effectively. I also liked how the tools are covered in the book. It is not a tool manual rephrased, but rather the whole tool use context related to the rest of the NSM. While the paradigm 'products perform collection, people perform analysis' might be faulty as the products are getting smarter, having training analysts still is one of the best investments in security. On the process side, the book covers complete analyst training. People are indeed the critical component of NSM, since most of the decision-making relies on trained analysts and their investigation, classification and escalation of alerts. A chapter on netflow and other types of session/connectivity data presents considerable interest to those monitoring networks. Example case studies show how such data helped identify intrusion action that did not directly product IDS alerts. Same applies to traffic visualization and statistical tools that enrich the IDS data and can sometimes provide early anomaly indications as well. Of course, NSM event-driven analysis is centered on Sguil - a new GUI frontend to NIDS, session and other context data, facilitating easy and effective event classification and escalation (if needed). Emergency NSM vs ongoing monitoring NSM procedures are also covered in the book. Even if the organization does not maintain an ongoing security monitoring program, it can still benefit from NSM that is deployed after a suspected intrusion. Attacks against NSM processes and technologies also fill dedicated section. Such attacks include intruder tools as well as attacks against the human (such overwhelming the analysts) and process components of the NSM. Overall, the book is a required reading for any security professional and those wishing to become one. It helps to broaden the horizons of seasoned professionals as well as educate the beginners in monitoring techniques. While value of NSM as an approach can be debated in modern organizations where tuned sensors and skilled analysts are an exception rather than the rule, the book is a superb security resource even for those who do not choose to implement NSM at the moment.
