📄️ Normalized Threat Rules
CSE's built-in threat rules pass alerts from a security product to the Signal generation process, and are normalized work across multiple security products.
📄️ Rule Tuning
Rule tuning expressions allow you to tailor the logic of a built-in rule without logic without replicating and modifying the rule.
