Question

How is single loss expectancy (SLE) calculated?This task contains the radio buttons and checkboxes for options. The shortcut keys to perform this task are A to H and alt+1 to alt+9. A Annualized rate of occurrence * asset value * exposure factor B Threat + vulnerability C Asset value ($) * exposure factor D Annualized rate of occurrence * vulnerability

Answer 1

Answer: C.) Asset value ($) * exposure factor

Explanation: The Single Loss Expectancy is used to evaluate the loss in monetary terms that will be incurred by an organization as a result of risk on it's asset. It is expressed mathematically as :

SLE = AV * EF

Where AV refers to the value of the organization's asset.

EF, the exposure factor ranges from 0 - 1 and it measures the fractional percentage of the asset which will be lost due to risk on such asset.

It is an important aspect of risk management or assessment in an organization and steps must be taken to lower the exposure factor of assets.
