Quantitative Risk Analysis

Method of evaluating risk that uses numerical measurements
Used for critical asset and risks that have high likelihood of occuring

Asset Value (AV)

The cost of an asset
Asset includes Tangible and Intangible objects

Exposure Factor (EF)

Proportion of an asset that is lost in an event
Represented as a percentage between 0% (No Loss) and 100% (Total Loss)

Single Loss Expectancy (SLE)

Monetary value expected to be lost in a single event
SLE = AV * EF

Annualized Rate of Occurrence (ARO)

Estimated frequency with which a threat is expected to occur within a year

Annualized Loss Expectancy (ALE)

Expected annual loss from a risk
ALE = SLE * ARO

Total Cost of Ownership (TCO)

Expected annual cost from implementing the mitigation strategies
