The U.S. government, through the Department of Homeland Security (DHS), has issued new security guidelines to protect critical infrastructure from AI-related threats. The guidelines emphasize the importance of using AI in a manner that respects privacy, civil rights, and civil liberties. The guidance focuses on various aspects of the AI lifecycle, including governance, mapping, measurement, and management. It suggests establishing an organizational culture of AI risk management and developing systems to assess and track AI risks. Critical infrastructure owners and operators are encouraged to consider sector-specific and context-specific use of AI when assessing risks and selecting appropriate mitigations. The release of these guidelines follows the Five Eyes intelligence alliance's warning about the need for careful setup and configuration of AI systems.
