Developing and Executing a Fully Informed OT Threat Hunt

This article provides practical guidance for conducting threat hunts across IT and OT environments, emphasizing the importance of intelligence-driven hypotheses, identifying and prioritizing data sources (e.g., Splunk and the Dragos Platform), documenting actions and findings, and engaging incident response when suspected adversary activity is found; it also discusses measuring maturity, avoiding analysis paralysis, addressing visibility gaps (such as unlogged routers), and producing strategic, operational, and tactical reports to communicate hunt outcomes and drive improvements.
