Defence Cyber Agency (DCyA)

Definition

A tri-service integrated agency of the armed forces, set up to handle the military dimension of cyber security and cyber operations across the Army, Navy and Air Force, under the Integrated Defence Staff.

Key points

• The Defence Cyber Agency was established in 2019 as one of three new tri-service agencies (alongside the Defence Space Agency and the Armed Forces Special Operations Division), created on the recommendation of reform committees to integrate emerging-domain capabilities.
• It functions under the Integrated Defence Staff and the Chiefs of Staff Committee, drawing personnel from all three services, and is headed by an officer of two-star rank (Rear Admiral or equivalent) on rotation.
• Its remit covers defensive and offensive cyber operations for the military, protection of defence networks, and coordination of cyber doctrine across the services; it works alongside, not in place of, civilian cyber bodies.
• Civilian cyber security is led by separate institutions: the National Cyber Security Coordinator, the Indian Computer Emergency Response Team (CERT-In) under the Ministry of Electronics and Information Technology, and the National Critical Information Infrastructure Protection Centre; the DCyA is the military-specific arm.
• It reflects the recognition of cyberspace as a distinct domain of warfare alongside land, sea, air and space.

Why it matters for CAPF

Cyber security as a national-security domain is a growing current-affairs theme; the 2019 creation of the DCyA, its tri-service nature, and the distinction from civilian bodies like CERT-In are useful institutional facts.

Common confusion

The DCyA is the military's tri-service cyber agency, distinct from civilian cyber bodies such as CERT-In (incident response) and the National Cyber Security Coordinator (overall civilian coordination). It is an integrated agency under the IDS, not a full command and not a single-service unit.
