On November 17, 2024, the U.S. Department of Homeland Security introduced its 'Roles and Responsibilities Framework for Artificial Intelligence in Critical Infrastructure.' Developed with AI developers, infrastructure operators, and civil society, the voluntary guidelines emphasize securing environments, responsible design, data governance, secure deployment, and performance monitoring. DHS Secretary Alejandro Mayorkas hailed it as a foundational step for AI governance, though some critics doubt voluntary adoption will suffice. The framework aims to harmonize international AI standards, ensuring safer, smarter U.S. infrastructure.
