SSCP Practice Question: Which metric is used to measure the potential…

Which metric is used to measure the potential loss from a single occurrence of a risk?

⚠ Common exam trap

ISC2 often tests the distinction between SLE and ALE, trapping candidates who confuse a single-event loss with an annualized figure, especially when the question explicitly asks for 'single occurrence' but the answer options include ALE as a distractor.

Correct answer & explanation

✓

Single Loss Expectancy (SLE)

The Single Loss Expectancy (SLE) is the metric used to measure the potential loss from a single occurrence of a risk. It is calculated as Asset Value (AV) multiplied by the Exposure Factor (EF), providing a dollar value for one incident. This directly answers the question of loss per single event.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Exposure Factor (EF)

    Why it's wrong here

    EF is percentage of asset lost.

  • ✗

    Annualized Loss Expectancy (ALE)

    Why it's wrong here

    ALE is annual expected loss.

  • ✗

    Annualized Rate of Occurrence (ARO)

    Why it's wrong here

    ARO measures frequency, not loss from a single event.

  • ✓

    Single Loss Expectancy (SLE)

    Why this is correct

    SLE is the monetary loss from a single occurrence.
