CISA Releases Zero Trust Guidance for Securing OT Against Cyber Threats

CISA released guidance, "Adapting Zero Trust Principles to Operational Technology," urging organizations in critical sectors (power, water, transportation) to adopt zero trust architectures for OT as IT/OT convergence increases cyber risk; the guidance outlines steps for asset visibility, identity and access controls, supply-chain risk management, and incident response, and warns that state-sponsored groups like Volt Typhoon are actively targeting OT environments.
