What We Talk About When We Talk About Risk

Measuring security risk is not that hard if you get your terms straight and leverage well-established methods and principles from other disciplines.

Re: Cybersecurity Risk Taxonomy
Small Business - general rule is that a small business (I guess 50 emps or less) can live for only 2 weeks following a major crash of systems.  I supported such shops and always had a backup-restore plan in working place and used it on several critical cases inclusive of server drive failure and ransomware attack.   Measure THAT!!!   (Lesson - always ask for a large check for services in such cases).

Re: Cybersecurity Risk Taxonomy
Thanks, Christian.  You're absolutely right about this problem being discussed for some time now.  Unfortunately, I don't believe it's broadly recognized yet as a foundational Achilles Heel for our profession.  Hopefully we can elevate it within the minds of our colleagues and accelerate the evolution of our profession.

Cheers

Jack

Cybersecurity Risk Taxonomy
These are excellent points - in fact, the very list of risks you noted that are typically raised when asked are the ones I tend to see in initial project documents that relate to security.

Cybersecurity Risk Taxonomy (A. M. Rea-Guaman, T. San Feliu, J. A. Calvo-Manzano, I. D. Sanchez-Garcia) is a paper published under the International Conference on Software Process Improvement, 2017. It covers an interesting deep dive into studies published from 1990 to 2017. They found "132 papers and some of them mention some risk taxonomies within the scope of IT (information technologies) cybersecurity, although only five primary elements were selected, identifying the main risk taxonomies."

The perspectives covered include Asset, Attacks, Service, Business and External, with papers covering a wide range of combinations of taxonomy descriptions. Some of the items in the taxonomies include Business objects and dynamics models, Social engineering, Systems and technology failures, Failed internal processes, Resource or target information and Actions of people.

Your example InfoSec risks make sense upon more reading of studies like the one above, which is a great piece indicating this conversation of risk in InfoSec has been going on for some time.
