With the increasing digitization and connectivity of operational technology (OT) networks, the threat landscape has expanded, making it imperative for organizations to proactively hunt for potential cyber threats. Threat hunting in OT networks involves actively and continuously searching for signs of compromise or malicious activity that traditional security measures might miss. This article dives deep into the concept of threat hunting in OT networks, its significance in protecting critical infrastructure, and effective strategies to unleash proactive cybersecurity.
Understanding Threat Hunting in OT Networks Threat hunting in OT networks is a proactive approach that aims to identify and mitigate advanced threats, including sophisticated attacks, zero-day exploits, and insider threats. It involves leveraging both human expertise and advanced technologies to detect anomalies, patterns, and indicators of compromise (IOCs) within the OT environment. By proactively seeking out threats, organizations have the ability to stay ahead of adversaries and minimize risks to operational continuity.
