India's internal security is increasingly shaped from outside: hostile states act through proxies and non-state networks to inflict harm below the threshold of war, across military, economic, cyber, social and coastal dimensions.

Challenges from external state actors

  • Proxy war: sponsorship of cross-border terrorism and infiltration, tunnels under the border and drones dropping arms and narcotics.
  • Economic subversion: counterfeit currency, narcotics and terror financing through hawala networks.
  • Cyber and information: state-linked attacks on infrastructure and disinformation aimed at communal, caste and regional fault lines.
  • Military pressure: border face-offs that tie down forces and embolden insurgents with sanctuaries across the frontier.

Challenges from non-state actors

  • Terror groups such as Lashkar-e-Taiba and Jaish-e-Mohammed, and insurgent outfits with camps abroad, mount attacks and recruit locally.
  • Drug cartels and arms smugglers fund and equip violence; coastal routes remain vulnerable, as the 2008 Mumbai attack showed.
  • Radical online networks spread propaganda and recruit youth, giving external actors a foothold within society.

Enablers

  • Porous and difficult borders, coastal gaps, weak local intelligence, social-media narratives and safe havens abroad.

Measures required

  • Borders and coast: fencing, surveillance and the Comprehensive Integrated Border Management System; layered coastal security; intelligence sharing between the Centre and States.
  • Legal and financial: UAPA and NIA Act amended in 2019, FATF-aligned action on terror financing, curbs on counterfeit currency and cyber monitoring.
  • Diplomatic: isolate sponsors at the UN and FATF, partner with friendly states and maintain credible deterrence.
  • Social and developmental: develop border and insurgency-affected areas, counter radicalisation online and through community policing.

Secure borders, agile intelligence, firm laws and diplomacy, combined with inclusive development, are the answer; none works alone.
