Cyber threat hunting is a proactive security discipline that searches networks and endpoints for hidden threats that bypass automated defenses. Unlike reactive threat detection, hunting starts with a hypothesis derived from threat intelligence, behavioral data, or analyst knowledge, then investigates and resolves findings. Four methodologies are covered: intelligence-driven, data-driven, knowledge-driven, and hybrid hunts. Best practices include knowing your environment, adopting an adversarial mindset, automating successful hunt queries into detection rules, and building dedicated hunt teams. Key tools include SIEM, EDR, and threat intelligence platforms. The post concludes with a pitch for Huntress Managed SIEM as a managed threat hunting solution.
