A security analyst is calculating the annualized loss expectancy (ALE) for a server. The single loss expectancy (SLE) is $5,000 and the annualized rate of occurrence (ARO) is 0.2. What is the ALE?
Trap 1: $0
Incorrect; ARO is not zero.
Trap 2: $5,200
Incorrect; that would be SLE + ARO (unrelated).
Trap 3: $25,000
That would be SLE / ARO.
- A
$0
Why wrong: Incorrect; ARO is not zero.
- B
$5,200
Why wrong: Incorrect; that would be SLE + ARO (unrelated).
- C
$1,000
Correct: $5,000 × 0.2 = $1,000.
- D
$25,000
Why wrong: That would be SLE / ARO.
