Question 15

SLE is used to calculate the impact to an organization per cybersecurity incident.

SLE, or Single Loss Expectancy, quantifies the potential loss an organization would incur from a single cybersecurity incident, making it a crucial metric for assessing risk.

A) SLE

SLE, or Single Loss Expectancy, directly measures the financial impact of a single cybersecurity incident. It is calculated by multiplying the asset value by the exposure factor, indicating the potential loss in monetary terms for each incident.

B) ALE

ALE, or Annual Loss Expectancy, represents the total expected loss for an organization due to cybersecurity incidents over a year. While it provides a broader view of risk over time, it does not specifically measure the impact of a single incident, making it less relevant for this question.

C) ARO

ARO, or Annual Rate of Occurrence, estimates how often a particular cybersecurity incident is expected to occur within a year. While it is part of the risk assessment process, it does not directly calculate the impact of an individual incident, thus not answering the question.

D) SLA

SLA, or Service Level Agreement, outlines the expected service performance and standards between a service provider and a client. It is not related to the calculation of impact from cybersecurity incidents, making it irrelevant in this context.

Conclusion

SLE is the definitive choice for calculating the impact of a single cybersecurity incident, as it focuses specifically on the financial loss associated with one occurrence. Other options, while related to risk assessment, fail to meet the criteria of measuring individual incident impact, thereby confirming SLE as the correct answer.
