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.

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.
