Final answer:
To calculate the Return on Investment (ROI) for a mitigation solution, calculate the Annual Loss Expectancy (ALE) which includes evaluating the Annual Rate of Occurrence (ARO) and the Single Loss Expectancy (SLE).The correct option is a).
Step-by-step explanation:
To determine the Return on Investment (ROI) of the middleware for mitigating a vulnerability in a legacy application, one would need to calculate the Annual Loss Expectancy (ALE). ALE is used to quantify the potential loss per year due to a risk and helps in assessing the cost-benefit of the mitigation solution such as purchasing middleware. The formula to determine ALE is ALE = SLE × ARO, where SLE is the Single Loss Expectancy and ARO is the Annual Rate of Occurrence. By comparing ALE to the cost of the middleware, the hospital can decide if the investment will have a positive ROI, meaning that the cost of the mitigation is less than the expected annual loss from the vulnerability.
The subject of this question is Business at a College level. In order to determine the Return on Investment (ROI) for the mitigation of the legacy web application vulnerability, several factors must be considered. The correct options to calculate ROI in this case are:
A. ALE: Annualized Loss Expectancy, which is the expected financial loss in a year due to the vulnerability.
B. RTO: Recovery Time Objective, which is the acceptable amount of time to recover from a vulnerability incident.
E. RPO: Recovery Point Objective, which is the acceptable amount of data loss in the event of a vulnerability incident.
