What term is a measure of the rate by which events occur over a certain period of time?

• A. Event
• B. Likelihood
• C. Frequency
• D. Magnitude

Answer: (C)

Frequency is the measure of how often events occur within a defined time period. It captures the rate at which events happen, such as incidents per month or per year, which is exactly what this question describes. In IT risk terms, you look at how frequently incidents or events are expected to occur to understand potential exposure over time. This differs from likelihood, which is the probability that an event will occur, not how often it happens in a given timeframe. It also differs from magnitude, which is about the size or impact of an event when it occurs, and from the event itself, which is just a single occurrence. So, the term that best fits “a measure of the rate by which events occur over a certain period of time” is frequency.
