Which agency is the lead for SIGINT?

• A. CIA
• B. NSA
• C. FBI
• D. DHS

Answer: (B)

Signals intelligence, or SIGINT, involves intercepting and analyzing electronic signals to gather information. The National Security Agency is the lead for SIGINT because it was designed specifically to develop and operate the cryptologic and interception capabilities needed to collect, process, and exploit signals from foreign and other sources. This specialized role sets NSA apart from other agencies. Other agencies have related but different missions. The CIA focuses more on overseas human intelligence and covert operations, using SIGINT outputs but not leading the collection and cryptanalytic efforts. The FBI handles domestic investigations and counterintelligence within the United States. DHS coordinates homeland security measures and protection. While they may use SIGINT information, they do not supervise or direct SIGINT activities at the national level the way NSA does.
