U/OO/145018-25 | PP-25-1731 | April 2025 Ver. 1.0 i Operational Technology Assurance Partnership: Smart Controller Security within National Security Systems Ongoing operational technology (OT) dependence on information technology (IT) and integrated communications and networking increasingly puts OT at risk.
