Internal Security › Security Forces mandate

India’s internal security landscape has become increasingly complex, characterized by the convergence of traditional threats and high-tech “Grey Zone” challenges.

Traditional Internal Security Challenges

Cross-Border Terrorism- Eg- The 2025 Pahalgam attack by the TRF (a proxy of LeT).

Left-Wing Extremism (LWE)- The “Red Corridor” remains a threat in core districts of Chhattisgarh and Odisha.

Insurgency in the North-East- Ethnic militancy and secessionist movements like NSCN (IM).

Communal and Sectarian Violence- Eg- Delhi Riots, 2020

Illegal Migration & Infiltration along Bangladesh and Myanmar borders. Eg- Rohingya

Organized Crime Syndicates-

Extortion and smuggling networks. Eg- D-Company

Drug Trafficking from Golden Crescent and Golden Traingle

Hawala & Fake Currency (FICN)- Illegal financial channels used to destabilize the economy.

Coastal Security Vulnerabilities

Piracy

Illegal deep sea fishing

Emerging Internal Security Challenges

Drone-Enabled Smuggling- Use of UAVs for drug and weapon drops.

Cyber-Warfare-

13.7% of global incidents target India (Cyfirma report)

Deepfakes & AI-Disinformation- Eg- Manipulated videos during the 2025 state elections.

Online Radicalization and “white-collar” terrorism. Eg- 2025 “Doctor Module” of Red Fort Blast.

Weapon Proliferation- Smuggling of sophisticated Western and Chinese arms from Myanmar’s black markets into Manipur.

Bangladesh Border (4,096 km)

Illegal Migration- Movement of undocumented individuals

Illegal Cattle Smuggling (billion-dollar) – leads to border skirmishes.

Bangladesh acts as a transit point for high-quality Fake Indian Currency Notes (FICN).

Human Trafficking- A major route for trafficking women and children for forced labor.

Radicalization Spillover- groups like Ansarullah Bangla Team (ABT) attempting to establish sleeper cells in West Bengal and Assam.
