OT systems are a prime target due to their criticality and the potential impact if these systems are disrupted. As the number and capability of threat actor targeting OT increases, so too does the need for robust cyber security controls.
However, the complexity, scale, and long-standing nature of OT systems often means organisations can lack a holistic view of their environment, which undermines their ability to implement effective cyber security measures. Traditionally, OT networks were isolated (or ‘air-gapped’) from the internet and external systems. However, modern operational demands have led to increased connectivity as networks now integrate with enterprise systems, third-party vendors and cloud services. This makes designing appropriate security controls increasingly critical, to reduce the risks to previously isolated systems.
