India's internal security is tested from within and across its borders, by terrorism, insurgency, extremism, organised crime and cyber attacks, so intelligence and investigation must work as one chain.
Internal security challenges
- Cross-border terrorism and infiltration in Jammu and Kashmir, sustained by external support.
- Left-wing extremism in central India and insurgency in parts of the North-East.
- Communal and caste violence, and online radicalisation.
- Emerging: cyber attacks on critical infrastructure, drug trafficking and narco-terror, terror financing and fake currency, and drone and maritime threats.
Central intelligence agencies
- Intelligence Bureau: domestic intelligence and counter-terrorism, tracking modules and radical networks.
- Research and Analysis Wing: external intelligence on threats that originate abroad.
- NTRO: technical intelligence, including satellite and cyber monitoring.
- FIU-IND: financial intelligence on suspicious transactions that fund terror and crime.
Central investigative agencies
- NIA: investigates and prosecutes terror and related offences across states.
- CBI: corruption and serious crime with inter-state or international ramifications.
- ED: money laundering under PMLA and foreign-exchange offences.
- NCB: narcotics trafficking, including its narco-terror links.
- CERT-In and the Indian Cybercrime Coordination Centre (I4C): incident response and coordination against cyber crime.
Coordination
- The Multi Agency Centre pools intelligence from central and state agencies; NATGRID links databases; state Special Branches and police remain the first responders.
Gaps
- Overlapping mandates, weak Centre-State coordination, no statutory basis or parliamentary oversight for the intelligence agencies, and limited cyber capacity.
Statutory clarity, Centre-State and inter-agency coordination and modern technical capacity would turn many agencies into one seamless security response.
