Which act requires that secured communications be monitored for foreign intelligence?

The Foreign Intelligence Surveillance Act (FISA) is specifically designed to govern the process by which the United States government can monitor and collect foreign intelligence information through secured communications. This act establishes legal procedures for surveillance and collection of foreign intelligence, particularly when it comes to conducting investigations involving foreign powers or their agents.

FISA reflects the balance the government seeks between national security needs and the protection of individual privacy rights, as it provides oversight and accountability measures through the Foreign Intelligence Surveillance Court. The act emphasizes the need for a legal framework in monitoring communications that may impact national security, particularly those that involve foreign individuals or entities.

In contrast, the Freedom of Information Act pertains to public access to government records; the Foreign Corrupt Practices Act addresses bribery of foreign officials; and the Fourth Amendment protects against unreasonable searches and seizures without proper warrants, making them unrelated to the specific monitoring of communications outlined in the correct response.
