Zero trust (ZT) offers a modern, adaptive approach to cybersecurity by eliminating implicit trust and continuously validating access based on identity, context, and risk. ZT principles assume a breach has already occurred and are designed to limit threat actor movement and potential damage.
For operational technology (OT), applying ZT requires careful consideration because OT systems interact with the physical environment and are constrained by availability and safety requirements, as well as legacy technology with long lifespans. The blanket application of traditional information technology (IT)-focused ZT capabilities to OT is neither reasonable nor feasible and requires continuous collaboration between OT engineers, IT architects, and cybersecurity professionals. This collaboration should include clear communication channels, joint development of policies and controls, and a shared understanding of both mission objectives and technical limitations.
