Which of the following terms related to risk management represents the estimated frequency at which a threat is expected to occur? Response:

A safeguard is a control implemented to protect an asset or reduce risk, not a measure of how frequently a threat occurs.

Single Loss Expectancy (SLE) is the monetary loss expected each time a specific threat materializes, not its frequency of occurrence.

Exposure Factor (EF) is the percentage of asset value lost due to a single successful threat event, not a measure of threat frequency.

Annualized Rate of Occurrence (ARO) is a quantitative risk assessment term that quantifies how often a specific threat event is likely to occur over a one-year period. It is a critical component used in calculating the Annualized Loss Expectancy (ALE).
