Question
Chapter 7, Problem 6E
Program Plan Intro
Single loss expectancy:
- The expected monetary loss every time a risk occurs is called the Single Loss Expectancy.
- The Single Loss Expectancy (SLE), Exposure Factor (EF) and Asset Value (AV) are related by the formula:
- SLE = EF * AV
- Introducing this conceptual breakdown of Single Loss Expectancy into Exposure Factor and Asset Value allows us to adjust the two terms independently and is related to risk management and risk assessment.
- Asset Value may vary with market changes, inflation while Exposure Factor can be reduced by enabling preventive measures.
Annualized loss expectancy:
- The product of the single loss expectancy (SLE) and the annual rate of occurrence (ARO) give annualized loss expectancy (ALE).
- It is mathematically expressed as:
- ALE = SLE * ARO
- The important feature of Annualized Loss Expectancy is that it can be used directly in a cost- benefit analysis.

- Which of the following is the best description of purpose of risk management? a. To implement measures to reduce risks to an acceptable level. b. To outline the threats to which IT resources are exposed. c. To determine the damage caused by possible security incidents. d. To determine the probability that a certain risk will occur.arrow_forwardA recommended approach is that the people assigned to implement a risk management program should begin by studying the models presented earlier in this chapter and identifying what each offers to the envisioned process. Once the organization understands what each risk management model offers, it can adapt one that is a good fit for the specific needs at hand. Which risk control strategy would you consider the most effective and why? When should the strategy be used and why should it not be used for all risks?arrow_forwardIt is important to understand that the distinction between Response and Recovery is often a fuzzy one, and that the end of one phase and the beginning of another depends on the Incident Commander declaring it to be so. Explain why the Recovery phase can be considered as a "window of opportunity" for Risk Reduction, and describe some kinds of Risk Reduction measures that are easier to achieve during Recovery than at other times (and WHY are they easier?).arrow_forward
