Final answer:
Cortex XDR supports Behavioral and Signature-based rules for threat detection; behavioral rules focus on anomalies, while signature rules rely on known threat patterns.
Step-by-step explanation:
The question you're asking about pertains to Cortex XDR, which is a security platform that helps organizations to detect and respond to threats. Cortex XDR supports two types of rules, and the correct types are b) Behavioral and Signature-based. Behavioral rules are designed to detect and flag activities that deviate from normal patterns or that match certain behavioral profiles, indicating a potential threat. On the other hand, signature-based rules are based on known threat signatures - identifiable patterns of data that signify malicious activity.
