Five industrial OT security essentials

Industrial operational technology (OT) networks are continually targeted. From the hacking of LNG producers just before Russia invaded Ukraine, Toyota’s temporary shutdown of 14 factories after a supplier was breached, or compromising a nuclear power plant’s ICS and SCADA systems, attacks against industrial operations appear never-ending. Air-gapping production floors is no longer a viable defense.

Mapping and understanding security posture and the complexities of protecting OT networks introduced many risks. Deployed on their own, intrusion detection systems (IDS) are 1) largely reactive, 2) overwhelm security teams with noise, and 3) fail to prioritize alerts by risk, context, and their potential impact. IDS solutions do not mitigate risk, nor prevent malicious attacks that harm business continuity and industrial operations.

An effective OT security solution should perform ongoing contextual risk assessment using data correlated from multiple, cross-domain sources. It should evaluate compliance, policies, and best practices to reduce risk and improve operational resilience.

The solution should prioritize risk mitigations based on their business impact and severity. IDS solutions provide an unmanageable flood of security alerts that cause alert fatigue and lack context-based insights. If provided, they would empower operational and security teams to focus on reducing risks that truly matter, correlated with their publicly known vulnerabilities.
