Before getting started on cyber risk quantification, let’s be clear on what we mean by measuring risk. On a weekly basis, we observe risk registers from organizations that are an absolute mess. They are flooded with entries that are inconsistently defined. If we don’t define risk consistently, then how we analyze it can’t be any better.
An automobile is an asset.
Can we measure the frequency and magnitude of an automobile? Nope.
Note: we see risk registers populated with assets like “cloud”, “mobile devices”, etc.
A teenage driver is a “threat”.
Can we measure the frequency and magnitude of a teenage driver? Nope.
Note: we see risk registers populated with threats like “malicious insider”, “nation-state”.
What can we measure?… An event!
When we assess risk (which is the frequency and magnitude of future loss) we can only assign those values to events.
Based on the information above we can surmise the risk (or substitute the word “event”) we are actually trying to measure is “How much risk is associated with automobile accidents caused by teenage drivers”.
