What does the NSA primarily handle?

The National Security Agency (NSA) primarily focuses on signals intelligence (SIGINT) and security. This encompasses the collection, analysis, and dissemination of information derived from intercepted communications and electronic signals. The NSA plays a critical role in national defense and information assurance by monitoring, protecting, and exploiting foreign communications and data systems to support U.S. national security goals.

Signals intelligence provides insights into adversaries' activities, intentions, and capabilities, enabling informed decision-making and strategic planning. The NSA also focuses on cybersecurity, ensuring the protection of national information infrastructures from cyber threats, which is a fundamental aspect of its mission.

The other options, while relevant to the broader intelligence community, do not align as specifically with the NSA's primary function. For instance, geospatial intelligence involves the use of imagery and geospatial data, human intelligence focuses on information gathered from human sources, and operational intelligence support refers to providing information necessary for conducting military operations. These areas may intersect with or support NSA's work, but they are not the core mission of the agency.
