New (IN)SECURE Magazine Features Bejtlich Article

The latest (IN)SECURE magazine was just published. Issue 1.4 features a 7-page article on Structured Traffic Analysis, a methodology to investigate network traces I developed for my Network Security Operations class.

It uses open source tools to perform zero-knowledge analysis of saved traffic. After reading this article, you may share the sentiments of a student in one of my recent classes who said "I’m embarrassed I ever used Ethereal to start network analysis!"

Awsome article Rich. This expands on the topics and tools you discuss in your NSM book. Statistical data is always something I tend to overlook and go straight for the content data, but as you point out in NSM, you don't always have content data available. But great article, I will have to try out Argus.

Very good article, can't wait to test out this method in a live scenario.

Although, you have to tell me what kind of compression tool you were using to fit a 2GB capture file on to a CD! ; )

I thought it was compressed. I routinely get database archives that are pretty large (in the excess of 20 - 40 Gb) that are compressed to less than a gig. I didn’t really question it...

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

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
