The union home minister proposed the Four-Dimensional Grid Border Security Model during his visit to the Sanchu Border Outpost on the India–Pakistan border in Rajasthan.
It is a new integrated border security framework to strengthen India's international border protection.
The model brings together the Border Security Force (BSF), Army, district administration, cyber surveillance units, and border residents under one coordinated system.
It aims to prevent infiltration, smuggling, drone intrusions, and cross-border terrorism through multi-layered security.
The framework uses technology such as cyber monitoring, drone tracking, real-time intelligence sharing, and advanced communication systems.
