A Lesson on Indications and Warning

I read a fascinating but scary Economist article titled Peril on the Sea. It presents classic examples of "indicators" that can be used to formulate intelligence "warnings" for decision-makers. (Indications and warning is defined in the DOD Dictionary of Military and Associated Terms. Definitions are taken from the DOD Joint Electronic Library's Joint Publication 1-02 [.pdf].) From the Economist article:

"According to a new study ("Security in Maritime Transport: Risk Factors and Economic Impact" [.pdf, overview]) by Aegis Defence Services, a London defence and security consultancy, these attacks represent something altogether more sinister. The temporary hijacking of the Dewi Madrim was by terrorists learning to drive a ship, and the kidnapping (without any attempt to ransom the officers) was aimed at acquiring expertise to help the terrorists mount a maritime attack. In other words, attacks like that on the Dewi Madrim are the equivalent of the al-Qaeda hijackers who perpetrated the September 11th attacks going to flying school in Florida."

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
