US government agencies led by CISA released Adapting Zero Trust Principles to Operational Technology, giving OT operators a framework to improve critical infrastructure security without undermining safety or uptime. The guide says traditional IT-centric controls do not map cleanly to OT because of legacy systems and limited visibility. It recommends asset inventories, network segmentation, MFA, and jump hosts to reduce risk in connected industrial environments.

    CISA-led zero-trust OT guidance released

    Industry Or Public Sector Update

    US government agencies led by CISA released Adapting Zero Trust Principles to Operational Technology, a joint guide for OT operators and security practitioners that applies zero-trust principles to critical infrastructure while preserving safety and uptime. The guidance says traditional IT-centric approaches do not map cleanly to OT because of legacy systems and limited visibility, and it recommends passive monitoring for asset inventories, network segmentation and microsegmentation, jump hosts with MFA, enhanced monitoring, and incident response planning aligned with operational constraints.
