CBROPS Exam - Question 284


What is a comparison between rule-based and statistical detection?

Show Answer
Correct Answer: A

Statistical detection is based on measured data since it relies on collecting data and applying statistical analysis. Rule-based detection, on the other hand, uses evaluated probability approaches, applying predefined rules that dictate actions based on the likelihood or possibility of certain events.

The correct answer is B. Remember that statistical will always involve probability. Rule based is based on measured data.

Statistical detection is based on observed data and uses probabilistic models to identify deviations from expected behavior (anomalies). Although it uses probability, it relies on measured data, not just theoretical assumptions. The option "Rule-based uses data known beforehand and statistical is based on assumptions" is correct because it reflects that rule-based detection uses prior knowledge (signatures or fixed rules), while statistical detection models normal behaviors (well-founded assumptions). The option "Statistical uses the probability approach while rule-based is based on measured data" is not valid because it claims that rule-based detection is based on measured data, which is incorrect: it is based on known rules, not on statistical measurements.
