CISA and U.S. partners published a joint guide to help OT owners and operators apply Zero Trust to operational technology environments, giving government and infrastructure stakeholders a practical resource for reducing cyber risk without disrupting critical systems. The guide addresses OT constraints such as legacy infrastructure, operational limits, and safety requirements while emphasizing stronger identity and access management. It also warns that Volt Typhoon and similar actors can exploit insecure pathways to reach both IT and OT networks.

CISA and federal partners publish Zero Trust OT guide
Initial DisclosureCISA, the Department of War, the Department of Energy, the FBI, and the Department of State published Adapting Zero Trust Principles to Operational Technology, a joint guide for OT owners, operators, and Zero Trust practitioners. The guide explains how to apply Zero Trust in operational technology environments without disrupting critical systems, with focus areas including zones and conduits, supply chain risk, and identity and access management, while noting that threat actors like Volt Typhoon target OT systems to compromise, escalate, and maintain access.
