What is a cost-benefit analysis (CBA) and how can it be calculated?

What will be an ideal response?


In its simplest definition, CBA (or economic feasibility) determines whether a particular control is worth its cost. CBAs may be calculated before a control or safeguard is implemented to determine if the control is worth implementing.?While many techniques exist, the CBA is most easily calculated using the ALE from earlier assessments before implementation of the proposed control, which is known as ALE(prior). Subtract the revised ALE, which is estimated based on the control being in place; this revised
value is known as ALE(post). Complete the calculation by subtracting the annualized cost of a safeguard (ACS).CBA = ALE(prior) - ALE(post) - ACS?wherethe annualized loss expectancy equals the single loss expectancy multiplied by the annualized rate of occurrence. ALE = SLE x AROand the single loss expectancy equals the exposure factor multiplied by the asset value,SLE = EF x AV.?
