The U.S. Department of Homeland Security has released a framework to guide the use of artificial intelligence (AI) in critical infrastructure sectors. The framework aims to mitigate risks associated with AI systems while promoting innovation. It provides guidance on AI governance, mapping AI system risk, and managing AI lifecycle risks. Key points include: 1) Establishing an AI governance structure to ensure responsible development and deployment. 2) Mapping AI system risk by identifying potential impacts and vulnerabilities. 3) Managing AI lifecycle risks through testing, monitoring, and incident response. 4) Promoting trustworthy AI through principles like transparency, fairness, and accountability. The framework is voluntary but encourages organizations to adopt responsible AI practices to enhance security and resilience.
