Definition/Scope: (JP 2-0) The National Security Agency is a cryptologic intelligence agency of the United States government, administered as part of the United States Department of Defense. It is responsible for the collection and analysis of foreign communications and foreign signals intelligence, which involves a significant amount of cryptanalysis.
