A manufacturing enterprise is conducting a quantitative risk analysis on a critical industrial control system (ICS) server. The server has an estimated Asset Value () of . A specific malware outbreak is projected to result in an Exposure Factor () of . Historical threat intelligence indicates that the Annualized Rate of Occurrence () for this type of attack is . What is the baseline Annualized Loss Expectancy () in dollars for this asset prior to implementing additional countermeasures?
Cevap: 24000 USD
Cevap
The baseline Annualized Loss Expectancy (ALE) for the industrial control system server is $24,000.
The baseline Annualized Loss Expectancy (ALE) is derived through standard quantitative risk modeling: first, Single Loss Expectancy (SLE) is calculated by multiplying Asset Value () by Exposure Factor (), yielding . Second, ALE is calculated by multiplying SLE () by Annualized Rate of Occurrence (), resulting in an annual loss expectancy of .
