Zorluk: KolayRisk Identification, Assessment, and Response Strategies

An IT risk manager evaluates a critical file storage server with an estimated asset value of $90,000. A recent threat assessment determines that a localized ransomware infection would result in an Exposure Factor (EF) of 30%. What is the Single Loss Expectancy (SLE) for this server in dollars?

Cevap: 27000 USD

Cevap

The Single Loss Expectancy (SLE) is $27,000.
Single Loss Expectancy (SLE) measures the financial loss incurred from a single risk event. It is computed using the formula SLE=AV×EFSLE = AV \times EF, where Asset Value (AV) is 90,000andExposureFactor(EF)is3090,000 and Exposure Factor (EF) is 30% ( 0.30 ).Multiplying). Multiplying 90,000 \times 0.30 gives gives 27,000.

Adım Adım Çözüm

1
Identify the key metric values provided in the scenario.
Asset Value (AV) = $90,000; Exposure Factor (EF) = 0.30.
These parameters are the necessary components to determine the potential loss from a single threat occurrence.
2
Apply the quantitative risk analysis formula for Single Loss Expectancy (SLE).
Formula: SLE=AV×EFSLE = AV \times EF
SLE measures the financial loss expected each time a specific risk materializes against an asset.
3
Multiply the total asset value by the exposure factor.
90,000×0.30=27,00090,000 \times 0.30 = 27,000
Calculates 30% of the total asset monetary value.
