Inputs vs Outputs, or Why Controls Are Not Sufficient

I have a feeling my post Consensus Audit Guidelines Are Still Controls is not going to be popular in certain circles. While tidying the house this evening I came across my 2007 edition of the Economist's Pocket World in Figures. Flipping through the pages I found many examples of inputs (think "control-compliant") vs outputs (think "field-assessed").

I'd like to share some of them with you in an attempt to better communicate the ideas my last post.

  • Business creativity and research


    • Input(s): Total expenditures on research and development, % of GDP

    • Output(s): Number of patents granted (per X people)


  • Education


    • Input(s): Education spending, % of GDP; school enrolment

    • Output(s): Literacy rate


  • Life expectancy, health, and related categories


    • Input(s): Health spending, % of GDP; population per doctor; number of hospital beds per citizen; (also add in air quality, drinking and smoking rates, etc.)

    • Output(s): Death rates; infant mortality; and so on...


  • Crime and punishment


    • Input(s): Total police per X population

    • Output(s): Crime rate



Is this making sense?

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...
