Domains Critical to Homeland Security Act

The Domains Critical to Homeland Security Act (S. 2525) authorizes the Department of Homeland Security (DHS) to identify and analyze specific sectors of the U.S. economy, technology, and infrastructure that are essential to national security. The bill directs the department to conduct research into how disruptions or foreign exploitation of these "critical domains"—such as supply chains, intellectual property, and emerging technologies—could threaten the country’s economic stability.

For everyday citizens, this legislation aims to better protect the essential services and industries that support daily life, such as energy, communications, and healthcare, from evolving global threats. By identifying vulnerabilities in these key areas before a crisis occurs, the government intends to strengthen the nation's ability to prevent large-scale economic disruptions and safeguard American innovation.
