About National Security Adviser
The National Security Advisor is the chief executive of the National Security Council (NSC). National Security Adviser is also the primary advisor to the Prime Minister of India on national and international security.
It is the National Security Advisor to whom intelligence agencies such as the Research and Analysis Wing and Intelligence Bureau report, rather than directly to the prime minister. Due to such vested powers NSA is a prominent and powerful office in the bureaucracy.
