During a risk assessment, a senior manager inquires about what the cost would be if a unique occurrence would impact the availability of a critical service. The service generates $1,000 in revenue for the organization. The impact of the attack would affect 20% of the server's capacity to perform jobs. The organization expects that five out of twenty attacks would succeed during the year. Which of the following is the calculated single loss expectancy?
Single Loss Expectancy (SLE) is calculated using the formula: SLE = Asset Value (AV) * Exposure Factor (EF). In this case, the Asset Value is $1,000 and the Exposure Factor is 20% (or 0.2). Therefore, SLE = $1,000 * 0.2 = $200.
ALE = SLE * ARO 1000 = SLE * 5 SLE = 200 Am I Right ?
The formula is correct, I'll go for A too.
I think, we don't know the ALE here, so i would calculate SLE=Asset Value * Exposure Factor=1000$ * 0.20=200$
Yes this is correct
AV = $1000 EF = 20% SLE is AV X EF SLE = 1000 X 0.20 = $200 The Additional information is for the ALE, but that's not needed.
