Describe the concept of threat hunting and its importance in modern cybersecurity.

Threat hunting is the proactive search for cyber threats that have evaded traditional security measures. Unlike reactive security monitoring, threat hunting assumes that threats are already present and actively searches for indicators of compromise. It combines human expertise with advanced analytics to identify sophisticated attacks, reduce dwell time, and improve overall security posture. Effective threat hunting requires deep understanding of normal network behavior, threat intelligence, and advanced analytical skills.
