What is the difference between statistical detection and rule-based detection models?

The correct answer is B. Statistical detection defines legitimate data of users over a period of time and rule-based. Statistical detection models build profiles based on the behavior of legitimate users or systems over time, defining what is considered normal. These models then flag deviations from this normal behavior, which may indicate anomalies or malicious activity. Statistical methods inv

Explanation

Statistical detection models build profiles based on the behavior of legitimate users or systems over time, defining what is considered normal. These models then flag deviations from this normal behavior, which may indicate anomalies or malicious activity. Statistical methods involve continuous learning and are often used for detecting unknown threats or abnormal behavior Rule-based detection models, on the other hand, work by using predefined rules and patterns, typically defined in an IF/THEN format. For example, "If traffic on port 22 increases beyond a certain threshold, then raise an alert." This method is effective for known threats where specific rules can be applied.
