5-Minute OT Cyber Resilience Guide
▼ Summary
– Understanding remote access points and supply chain connections is essential for OT cybersecurity resilience.
– Specialized sensors are needed to monitor OT networks, which differ from traditional IT systems.
– Knowing what normal behavior looks like and linking changes to management systems are critical practices.
– Maintaining accurate asset inventories is a key component of OT cybersecurity.
– Availability is the top priority in OT, and resilience means keeping systems safe and operational during cyberattacks.
Understanding the fundamentals of operational technology (OT) cybersecurity resilience is essential for protecting critical infrastructure from modern threats. In a recent video discussion, Rob Demain, CEO of e2e-assure, outlines practical steps organizations can take to strengthen their defenses. He stresses that identifying all remote access points and supply chain connections forms the foundation of any robust security strategy, since these are common entry vectors for attackers.
Demain points out that specialized monitoring sensors are necessary because OT environments operate differently from standard IT networks. These systems require tailored solutions that can detect anomalies without disrupting industrial processes. Knowing what constitutes normal network behavior allows teams to spot deviations quickly, linking any unusual activity directly to management systems for immediate investigation.
Maintaining an accurate and up-to-date asset inventory is another critical component Demain highlights. Without a clear picture of all connected devices and systems, vulnerabilities can easily go unnoticed. He concludes by reinforcing that system availability remains the highest priority in OT settings. True cyber resilience means ensuring that operations continue safely and reliably, even when facing an active cyber incident.
