Effective threat investigation is the art of turning noise into actionable intelligence. It requires a blend of structured frameworks (MITRE, Diamond Model), technical proficiency (Pivot Points), and human intuition (Curiosity). By formalizing the investigation process, SOC analysts can reduce dwell time, mitigate damage, and stay ahead of adversaries.
