In the second volume of the TaoSecurity Blog series, Mr. Bejtlich addresses how to detect and respond to intrusions using third party threat intelligence sources, network data, application and infrastructure data, and endpoint data. He assesses government and private security initiatives and applies counterintelligence and counteradversary mindsets to defend digital assets. He documents the events of the last 20 years of Chinese hacking from the perspective of a defender on the front lines, in the pre- and post-APT era.
This volume contains some of Mr. Bejtlich’s favorite posts, such as histories of threat hunting, so-called black and white hat budgeting, attribution capabilities and limits, and rating information security incidents. He has written new commentaries to accompany each post, some of which would qualify as blog entries in their own right. Read how the security industry, defensive methodologies, and strategies to improve national security have evolved in this new book, written by one of the authors who has seen it all and survived to blog about it.
In the first volume of the TaoSecurity Blog series, Bejtlich addresses milestones, philosophy and strategy, risk, and advice. Bejtlich shares his thoughts on leadership, the intruder's dilemma, managing burnout, controls versus assessments, insider versus outsider threats, security return on investment, threats versus vulnerabilities, controls and compliance, the post that got him hired at a Fortune 5 company as their first director of incident response, and much more.

In The Practice of Network Security Monitoring, Mandiant CSO Richard Bejtlich shows you how to use NSM to add a robust layer of protection around your networks—no prior experience required. To help you avoid costly and inflexible solutions, he teaches you how to deploy, build, and run an NSM operation using open source software and vendor-neutral tools.
You'll learn how to:
–Determine where to deploy NSM platforms, and size them for the monitored networks
–Deploy stand-alone or distributed NSM installations
–Use command line and graphical packet analysis tools, and NSM consoles
–Interpret network evidence from server-side and client-side intrusions
–Integrate threat intelligence into NSM software to identify sophisticated adversaries
There’s no foolproof way to keep attackers out of your network. But when they get in, you’ll be prepared. The Practice of Network Security Monitoring will show you how to build a security net to detect, contain, and control them. Attacks are inevitable, but losing sensitive data shouldn't be.
In the first three volumes of the series, Mr. Bejtlich selected and republished the very best entries from 18 years of writing and over 18 million blog views, along with commentaries and additional material.
In this title, Mr. Bejtlich collects material that has not been published elsewhere, including articles that are no longer available or are stored in assorted digital or physical archives.
Volume 4 offers early white papers that Mr. Bejtlich wrote as a network defender, either for technical or policy audiences. It features posts from other blogs or news outlets, as well as some of his written testimony from eleven Congressional hearings. For the first time, Mr. Bejtlich publishes documents that he wrote as part of his abandoned war studies PhD program. This last batch of content was only available to his advisor, Dr. Thomas Rid, and his review committee at King's College London.

In the third volume of the TaoSecurity Blog series, Mr. Bejtlich addresses the evolution of his security mindset, influenced by current events and advice from his so-called set of "wise people." He talks about why speed is not the key to John Boyd's OODA loop, and why security strategies designed for and by the "security 1%" may be irrelevant at best, or harmful at worst, for the remaining "99%". His history section explores the origins of the terms threat hunting and indicators of compromise, and reveals who really created the quote "there are two types of companies." His chapter on law highlights traps that might catch security teams, with advice to chief information security officers.
This volume contains some of Mr. Bejtlich’s favorite posts, such as Marcus Ranum's answer to what happens when security teams confront professionals, or how the Internet continues to function despite constant challenges, or reactions to comments by Dan Geer, Bruce Schneier, Marty Roesch, and other security leaders. Mr. Bejtlich has written new commentaries to accompany each post, some of which would qualify as blog entries in their own right.

"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.
