An organization evaluates the financial impact of a potential security breach on its primary cloud backup repository. The repository has an estimated Asset Value ( $AV$ ) of $\$50,000$ . Security analysts determine that a severe ransomware infection would result in an Exposure Factor ( $EF$ ) of $40\%$ . What is the Single Loss Expectancy ( $SLE$ ) in dollars for this asset?

Cevap: 20000 $

Cevap

The Single Loss Expectancy (SLE) for the cloud backup repository is $20,000.

Single Loss Expectancy (

SLE

) measures the total monetary loss resulting from a single risk event. It is calculated using the formula

SLE = AV \times EF

. Substituting the given values yields

SLE = \$50,000 \times 0.40 = \$20,000

Adım Adım Çözüm

Identify the quantitative risk formula for Single Loss Expectancy (SLE).

SLE = AV \times EF

Single Loss Expectancy measures the monetary loss expected each time a threat realizes against an asset.

Multiply the Asset Value (

AV

) of

50,000 by the Exposure Factor (

EF$) of 0.40.

20,000

Applying the 40% loss percentage to the full asset value yields the expected financial loss per incident.
