Calculate Annual Loss Expectancy for quantitative risk analysis

Calculate Annual Loss Expectancy (ALE) using the standard quantitative risk formula: ALE = SLE × ARO. Input asset value, exposure factor, and annual rate of occurrence to determine expected yearly losses. Includes monthly and daily loss projections, and optional control cost-benefit analysis with ROI calculation to justify security investments.
