Risk

Likelihood and impact (or consequence) of a threat actor exercising a vulnerability.

The Explain card

Plain English
Risk is the combination of how likely it is that a threat actor exploits a vulnerability and how bad the consequences would be if they did. Likelihood times impact.
Example
An internal AI assistant reaches HR documents through retrieval. The vulnerability is prompt injection via uploaded files. Likelihood is moderate because staff upload external documents daily; impact is high because salaries and disciplinary records could leak. That combination makes it a high risk worth fixing first.
Why it matters
Defenders cannot fix everything. Scoring risk lets you spend limited time and budget on the exposures that actually matter, and explain the choice to leadership.
Hook
Risk equals how likely, times how much it hurts.

Where it came from
Origin
French risque, from Italian risco or rischio, from rischiare, to run into danger, of uncertain further origin
Entered the language

What changed
It entered English as a merchant word for the chance of loss on a voyage or a venture. Insurers in the early 1700s priced that chance as a line of business. Engineering and later security work treated it as a scored quantity that can be accepted, transferred, reduced, or avoided.
How it is spelled

Pattern
i spells short /ɪ/ before a final consonant cluster, as in list and mist

Breaks the pattern
Seventeenth-century English still wrote this word as risque before the k spelling settled
