Why Zero Trust Fails in IoT and OT: A Linkage Perspective
⚠️ Zero trust principles deliver measurable gains in enterprise IT, but they often miss dominant failure modes in IoT and OT. The author argues that zero trust assumes explicit, identity-centric and continuously enforceable trust, while IoT/OT systems rely on implicit, durable trust relationships and centralized control paths. Adopt the unified linkage model (ULM) to map adjacency, inheritance and trust propagation, and prioritize protection of management planes, firmware update paths and vendor integrations.
