What is the difference between the rule-based detection when compared to behavioral detection?

Rule-based detection involves identifying malicious activities based on predefined rules or patterns of known attacks; it does not adapt or change with new data. In contrast, behavioral detection adapts over time by learning from new data; it identifies malicious activities based on deviations from established norms or behaviors. References: CiscoCertified CyberOps Associate Overview, Section 1.0: Security Concepts, Subsection 1.1: Compare and contrast the characteristics of data obtained from taps, NetFlow, and packet capture)
