National Security Division
Mission
The mission of the National Security Division is to protect the United States from threats to our national security by pursuing justice through the law. The NSD's organizational structure is designed to ensure greater coordination and unity of purpose between prosecutors and law enforcement agencies, on the one hand, and intelligence attorneys and the Intelligence Community, on the other, thus strengthening the effectiveness of the federal government's national security efforts.

FISA, as amended, establishes procedures for the authorization of electronic surveillance, use of pen registers and trap and trace devices, physical searches, and business records for the purpose of gathering foreign intelligence. It also established the United States Foreign Intelligence Surveillance Court (FISC), a special U.S. Federal court that holds nonpublic sessions to consider issuing search warrants under FISA.
The Office supports U.S. victims of terrorism overseas by helping them navigate foreign criminal justice systems and by advocating for their voices to be heard around the world.
