Department Of Homeland Security

The Department of Homeland Security (DHS) is a U.S. federal agency responsible for protecting the nation's infrastructure, border security, and cybersecurity. For AI governance, DHS plays a critical role in setting standards for AI use in critical infrastructure protection, immigration enforcement, and cybersecurity threat detection, while also addressing risks from AI-enabled threats. Enterprises operating in regulated sectors such as energy, transportation, and telecommunications must align their AI systems with DHS guidelines and coordinate on AI-related security incidents affecting national infrastructure.
