Question

Difference between statistical anomaly detection and rule based detection

Answer 1

Answer:

Statistical anomaly detection involves the collection of data relating to the behavior of legitimate users over a period of time. Then statistical tests are applied to observed behavior to determine with a high level of confidence whether that behavior is not legitimate user behavior. Rule-Based Detection involves an attempt to define a set of rules that can be used to decide that a given behavior is that of an intruder.
