The Director of the National Security Agency (DIRNSA) is the highest-ranking official in the National Security Agency, which is a Defense Agency within the U.S. Department of Defense. The Director of the NSA also concurrently serves as Chief of the Central Security Service (CHCSS) and as Commander of U.S. Cyber Command (USCYBERCOM). As DIRNSA/CHCSS the officeholder reports through the Under Secretary of Defense for Intelligence, and as CDRUSCYBERCOM through the Commander of U.S. Strategic Command, to the Secretary of Defense.
According to 10 U.S.C. § 201 of the United States Code, the DIRNSA/CHCSS/CDRUSCYBERCOM is recommended by the Secretary of Defense and nominated for appointment by the President. The nominee must be confirmed via majority vote by the Senate. In accordance with Department of Defense Directive 5100.20, dated December 23, 1971, the Director of the NSA must always be a commissioned officer of the military services. Because the assignment is currently part of a tri-hatted position, the Director of the NSA is appointed to the grade of a four-star general or admiral during the period of his incumbency. The Deputy Director is always a technically experienced civilian.
