What is Defense & Security?

Defense & Security technology encompasses the systems that support military operations, intelligence analysis, homeland security, and national defense infrastructure. This includes Command and Control (C2) systems, defense logistics and supply chain, surveillance and reconnaissance, military communications, and cybersecurity operations centers. India's defense technology ecosystem involves DRDO (Defence Research and Development Organisation), HAL (Hindustan Aeronautics), BEL (Bharat Electronics), and a growing private sector including Tata Advanced Systems, L&T Defence, and defense tech startups. Understanding this domain teaches you mission-critical system design, real-time data fusion, secure communications, and high-availability architectures.
