The Indian Intelligence Community (IIC) is a complex multi-layered network of intelligence agencies and their subordinate offices designed to conduct law enforcement, counterintelligence, foreign intelligence, internal security, military intelligence, financial intelligence and covert operations to protect the national security interests of the Republic of India. The oversight of intelligence operations in India are delegated by multiple agencies, responsible for work within their specific fields that disclose intelligence to their respective ministry.

The IIC is overseen by an National Security Advisor (NSA) which directly advises the Prime Minister of India on national security policy and international affairs. The NSA and the National Security Council Secretariat oversees the functioning of the IIC, which includes agencies such as the Research and Analysis Wing (R&AW), Intelligence Bureau (IB), and National Investigation Agency (NIA). The NSA plays a key role in coordinating the efforts of these agencies, ensuring that national security policies are aligned with the interests of India.

The DG reports to the Chief of Defence Staff (CDS). It is supposed to be the nodal agency for all defence-related intelligence, thus distinguishing it from the R&AW. Much of the agency's budget and operations are classified.

DIA has control of MoD's prized technical intelligence assets – the Directorate of Signals Intelligence and the Defence Image Processing and Analysis Centre (DIPAC). While the Signals Directorate is responsible for acquiring and decrypting enemy communications, the DIPAC controls India's satellite-based image acquisition capabilities. The DIA also controls the Defence Information Warfare Agency (DIWA) which handles all elements of the information warfare repertoire, including psychological operations, cyber-war, electronic intercepts and the monitoring of sound waves. Before the creation of the Defence Intelligence Agency, the military intelligence capability of India's armed forces was limited to Field Intelligence Units (FIU) and separate intelligence arms of the services.[13] These distinct services were not able to effectively coordinate intelligence operations and sharing of information.[14] The armed forces also heavily relied on civilian intelligence agencies such as the Research and Analysis Wing and the Intelligence Bureau.[13] With wide-ranging resources and functions, the DIA will be superior to and coordinate the Directorate of Military Intelligence, Directorate of Air Intelligence and the Directorate of Naval Intelligence.[14]
