How are you calculating a risk score/risk rating? : r ... - Reddit
...The process we use with clients is a manual one based on NIST 800-30. On the more basic side you can use ordinal rankings and derive a risk score = (likelihood x impact). More advanced you could leverage the OpenFAIR methodology to derive an Annual Loss Expectancy (ALE). This considers loss event frequency and primary/secondary loss magnitudes....
