National Security and Defence – Large Columns for Sovereignty in a Nation

In today’s complex global scenario, national security and defence are not just military discussions – they are a lifeline for a superb state. The existence, stability, and prosperity in each country are tied to the ability to protect their people, fields, resources, and strategic interests from threats, both internal and external.

From traditional armed conflict to modern cyber threats, the concept of security has developed significantly. This blog puts a deep dive into the columns in national defence, India’s approach, new dangers, and an active security mechanism requires an hour.

What is National Security?

National security refers to a country’s own sovereignty, regional integrity, and the ability to protect the social structure from the dangers that can arise externally (enemy states, terrorism, wars) or internally (rebellion, cyber attacks, civilian unrest).

It includes:

• Military defence
• Economic stability
• Cybersecurity
• Energy and food security
• Political integrity
• Environmental resilience

Why is National Defence Important?

1. Protects sovereignty: prevents external dominance and protects boundaries.
2. Maintaining law and order: count rebellion, terrorism, and riots.
3. Protects National Assets: Safeguards critical infrastructure, defence establishments, and data networks.
4. Ensures Global Standing: A secure country commands respect in diplomacy and trade.
5. Promotes Economic Growth: Investors and industries thrive in a safe environment.

The main component of a strong national defence system

1. Armed forces (Army, Navy, Air Force)

• Land Borders (Army) – Guards Line of Control (LOC), Line of Real Control (LAC), and international boundaries.
• Maritime Security (Navy) – protects the huge coastline in India and the EEZ (exclusive economic zone).
• Air superiority (air defence) – Air monitoring, rapid attacks, and defence ensure.

2. Strategic Forces Command (SFC)

• Manages India’s nuclear weapons and doctrine of credible minimum deterrence.

3. Paramilitary and Central Armed Police Forces

• CRPF, BSF, ITBP, CISF, and SSB handle internal security, border handling, resistance, and VIP protection.

4. Intelligence Agencies

• RAW (external intelligence), IB (internal intelligence), and NTRO (technical surveillance) play critical roles in threat prevention.

Modern Threats to National Security

1. Terrorism and Radicalisation

• Cross-border and homegrown threats destabilise peace.
• Counter-terrorism operations (like in Kashmir) demand coordination between the army, intelligence, and police.

2. Cybersecurity Threats

• Hacking of defence systems, ransomware attacks, and data leaks.
• Cyber units like CERT-IN, National Cyber Security Policy 2013, and DRDO’s cyber divisions address these.

3. Border Tensions and Proxy Wars

• Frequent standoffs with China (LAC) and Pakistan (LoC).
• Use of proxy fighters, like non-state actors, adds complexity.

4. Economic Espionage and Data Warfare

• Global competition leads to digital warfare, where states target economic infrastructure or financial systems.

5. Natural Disasters and Biological Threats

• Pandemics like COVID-19 showed that health is national security.
• Environmental degradation and climate change increase migration, conflict, and instability.
