Adapting Zero Trust Principles to Operational Technology
CISA, in coordination with the Department of War, Department of Energy, Federal Bureau of Investigation, and Department of State, released Adapting Zero Trust Principles to Operational Technology, joint guidance for organizations applying zero trust (ZT) principles to operational technology (OT). Zero trust is a modern, adaptive approach to cybersecurity that eliminates implicit trust and requires continuously validating access based on identity, context, and risk.
