Threat Hunting Part 1: Improving Through Hunting

This post introduces threat hunting for industrial control system (ICS) networks, arguing that proactive, iterative hunts can overcome visibility gaps, knowledge silos, and organizational/process weaknesses that hinder effective defense. Through illustrative vignettes, it highlights how hunting validates network understanding and security visibility while maturing incident response, emphasizing that success should be measured not only by finding threats but by improving people, processes, and technology to make ICS defenses empirically effective.
