Once your security is breached, everyone will ask the same question: now
what? Answering this question has cost companies hundreds of thousands of
dollars in incident response and computer forensics fees. This book reduces
the investigative workload of computer security incident response teams
(CSIRT) by posturing organizations for incident response success.
Firewalls can fail. Intrusion-detection systems can be bypassed. Network
monitors can be overloaded. These are the alarming but true facts about
network security. In fact, too often, security administrators' tools can serve as
gateways into the very networks they are defending.
Now, a novel approach to network monitoring seeks to overcome these
limitations by providing dynamic information about the vulnerability of all
parts of a network. Called network security monitoring (NSM), it draws on a
combination of auditing, vulnerability assessment, intrusion detection and
prevention, and incident response for the most comprehensive approach to
network security yet. By focusing on case studies and the application of opensource
tools, the author helps readers gain hands-on knowledge of how to
better defend networks and how to mitigate damage from security incidents.
Quickly develop and apply the skills needed to detect, prevent, and respond to new and emerging computer security exploits.
° Explores examples of actual compromised networks to illustrate how losses could have been avoided through network security monitoring.
° Written by Richard Bejtlich--a recognized authority and speaker on digital security.
° Foreword by Ron Gula, the original author of the Dragon intrusion detection system.
° Launch at Black Hat USA, July 26-29, 2004 in Las Vegas.

"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.
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.
