IT286Unit1Assignment.docx Unit 1 Assignment Purdue University Global IT286 – Network Security Concepts Unit 1 Assignment Part 1 – Section 1 SLE x ARO = ALE According to Medium.com, SLE stands for Single Loss Expectancy, ARO stands for Annualized Rate of Occurrence, and ALE stands for Annual Loss Expectancy. Single Loss Expectancy (SLE) is a monetary value that you can expect to lose with a genuine risk at any time. Annualized Rate of Occurrence (ARO) is a percentage calculated by the chance of real risk. Annual Loss Expectancy (ALE) is the numerical value measured that the substantial risk turns in one year.This means that the Single Loss Expectancy multiplied by the Annualized Rate of Occurrence equals the Annual Loss Expectancy, or the monetary value you can expect to lose at any time multiplied by the percentage calculated by the chance of risk equals the numerical value that the risk turns within one year. SLE has to be calculated first before you can complete the above calculation. Single Loss Expectancy is obtained by SLE = AV x EF. We already know that SLE stands for Single Loss Expectancy, AV is the asset's value, and EF is the exposure factor. Exposure Factor is the loss that will happen to the asset when exposed to a threat in a percentage. So this means that to calculate the Single Loss Expectancy, we must first multiply the exposure factor's asset value. If an asset's value, such as a production machine, is $100,000, and the exposure factor is 30% (essentially a machine f. . . . . .. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. . .. .. . . . . . . . . . . . . . . . . . .. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
