Sample Extrusion Detection Chapter Posted

My publisher just posted Chapter 4: Enterprise Network Instrumentation from my new book, Extrusion Detection: Security Monitoring for Internal Intrusions. The table of contents, preface, foreword by Marcus Ranum, and index are also all online. Marcus' foreword (.pdf) is a different than most; he interviews me. For example:

"MJR: I’ve noticed you’re a fan of Bruce Lee! It’s interesting to me how a lot of us security guys find parallels between computer/network security and the martial arts/art of war. Remember Lee’s great “It’s like a finger pointing away to the moon” speech? What do you think would be the equivalent for a student of computer security? What do you think Bruce would tell us?

RB: I am indeed a fan of Bruce Lee, and I’ve practiced several martial arts... I advise that intruders should be viewed as smart (sometimes smarter than you) and unpredictable, and able to beat your defenses. Bruce would probably agree. He would train to be ready for whatever his opponent would deliver, and he would have techniques in place to deal with the consequences of not blocking an initial punch or kick. Rather than failing catastrophically when an opponent lands a blow, Bruce would take advantage of the attacker’s proximity to initiate a different sort of counterattack or improved defense."

The chapters are as follows:

  1. Network Security Monitoring Revisited

  2. Defensible Network Architecture

  3. Extrusion Detection Illustrated

  4. Enterprise Network Instrumentation

  5. Layer 3 Network Access Control

  6. Traffic Threat Assessment

  7. Network Incident Response

  8. Network Forensics

  9. Traffic Threat Assessment Case Study

  10. Malicious Bots



  • Epilogue

  • Appendix A: Collecting Session Data in an Emergency

  • Appendix B: Minimal Snort Installation Guide

  • Appendix C: Survey of Enumeraiton Methods

  • Appendix D: Open Source Host Enumeration


The book should begin shipping tomorrow. If you have any suggestions for errata, please send them to me via richard at taosecurity dot com. Thank you!

Zeek in Action Videos

Image
This is a quick note to point blog readers to my Zeek in Action YouTube video series for the Zeek network security monitoring project .  Each video addresses a topic that I think might be of interest to people trying to understand their network using Zeek and adjacent tools and approaches, like Suricata, Wireshark, and so on.  I am especially pleased with Video 6 on monitoring wireless networks . It took me several weeks to research material for this video. I had to buy new hardware and experiment with a Linux distro that I had not used before -- Parrot .  Please like and subscribe, and let me know if there is a topic you think might make a good video.

MITRE ATT&CK Tactics Are Not Tactics

Image
Just what are "tactics"? Introduction MITRE ATT&CK  is a great resource, but something about it has bothered me since I first heard about it several years ago. It's a minor point, but I wanted to document it in case it confuses anyone else. The MITRE ATT&CK Design and Philosophy document from March 2020 says the following: At a high-level, ATT&CK is a behavioral model that consists of the following core components: • Tactics, denoting short-term, tactical adversary goals during an attack; • Techniques, describing the means by which adversaries achieve tactical goals; • Sub-techniques, describing more specific means by which adversaries achieve tactical goals at a lower level than techniques; and • Documented adversary usage of techniques, their procedures, and other metadata. My concern is with MITRE's definition of "tactics" as "short-term, tactical adversary goals during an attack," which is oddly recursive. The key word in the tacti...
