Annual loss expectancy (ALE) is a method to assign a monetary value to risk by multiplying the probability of a risk event by the potential loss associated with that event1. ALE can be used to compare the costs and benefits of different risk mitigation options and to determine the optimal level of investment in risk management2. Business impact analysis (BIA) is a process to identify and evaluate the potential effects of a disruption on the critical functions and processes of an organization3. BIA can help to forecast the impacts of a risk event, but it does not assign a monetary value to the risk itself. Cost-benefit analysis (CBA) is a technique to compare the costs and benefits of a project, decision, or action4. CBA can help to evaluate the feasibility and profitability of a risk mitigation option, but it does not assign a monetary value to the risk itself. Inherent vulnerabilities are the weaknesses or flaws in a system, process, or asset that expose it to potential threats5.
Inherent vulnerabilities can increase the likelihood or impact of a risk event, but they do not assign a monetary value to the risk itself. References = Risk and Information Systems Control Study Manual, Chapter 2: IT Risk Assessment, Section 2.2: Risk Analysis, pp. 77-81.
