Back from Bro Workshop

Last week I attended the Bro Hands-On Workshop 2009. Bro is an open source network intrusion detection and traffic characterization program with a lineage stretching to the mid-1990s. I finally met Vern Paxson in person, which was great. I've known who Vern was for about 10 years but never met him or heard him speak.

I first covered Bro in The Tao of Network Security Monitoring in 2004 with help from Chris Manders. About two years ago I posted Bro Basics and Bro Basics Follow-Up here. I haven't used Bro in production but after learning more about it in the workshop I would be comfortable using some of Bro's default features.

I'm not going to say anything right now about using Bro. I did integrate Bro analysis into most of the cases in my all-new TCP/IP Weapons School 2.0 class at Black Hat this year. If TechTarget clears me for writing again in 2009 I will probably write some Bro articles for Traffic Talk.

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...
