A security analyst is performing a quantitative risk analysis. The risk analysis should show the potential monetary loss each time a threat or event occurs. Given this requirement, which of the…

ALE (Annualized Loss Expectancy) represents the expected yearly monetary loss (ALE = SLE × ARO), not the loss per single occurrence of a threat event.

Asset Value (AV) represents the monetary worth of the asset being protected, which is a required input for calculating Single Loss Expectancy (SLE = AV × EF), directly contributing to the potential monetary loss per event.

ARO (Annualized Rate of Occurrence) represents how often a threat is expected to occur per year, not the monetary loss associated with a single occurrence.

Exposure Factor (EF) is the percentage of asset value lost when a specific threat occurs; combined with AV, it produces the SLE, which is exactly the 'potential monetary loss each time a threat or event occurs' the analyst needs.

ROI (Return on Investment) measures the financial benefit gained from a security control investment relative to its cost, not the monetary loss from a specific threat event.
