Is the National Security Agency (NSA) authorized to protect critical military infrastructure under Title 50?

The correct response is that the National Security Agency (NSA) is not authorized to protect critical military infrastructure under Title 50. Title 50 of the United States Code primarily pertains to war and national defense and governs intelligence activities. While the NSA plays a critical role in national security and intelligence gathering, its primary mandate revolves around signals intelligence and information assurance, rather than direct physical protection of military infrastructure.

Protection of military infrastructure typically falls under the purview of the Department of Defense (DOD) and other military entities. The NSA may support DOD efforts through intelligence and cybersecurity initiatives, but direct protection measures would not be under its Title 50 authorities. Therefore, characterizing the NSA's role as one of direct protective authority over military infrastructure misrepresents its intended functions and legal framework.
