Security is one of the most basic requirements of any human society. For a long time, security was understood primarily in military terms, as the protection of a state's territory and population from external military threats. This traditional conception of security focused on military alliances, arms, deterrence and the balance of power. In the contemporary world, however, the meaning of security has expanded considerably. Security now includes not only military threats but also economic, environmental, health and human security concerns. Non-military threats such as poverty, disease, climate change and terrorism are now recognised as equally serious for the security of people and states.
The study of security in the contemporary world is therefore more complex than it was during the Cold War. It involves different levels of analysis, from the individual to the global, and different approaches, from the realist focus on military power to the wider conception of human security. This chapter explains the traditional and non-traditional conceptions of security, the different dimensions of security threats, and the various ways in which states and societies try to provide security.
The traditional conception of security is state-centric. It treats the state as the primary actor and security as the protection of the state from external threats. In this view, security means the ability of a state to defend its sovereignty, territorial integrity and national interests against external aggression. The traditional conception dominated international relations during the Cold War, when the world was divided into two hostile blocs.
In the traditional view, the main threats to security come from other states and their military power. States therefore seek to protect themselves by building their own military strength, forming alliances, and maintaining a balance of power. The concept of deterrence is central: a state tries to convince a potential aggressor that any attack would be met with unacceptable retaliation, thereby preventing the attack from taking place.
Traditional security relies on several methods. The first is military power, including standing armies, navies, air forces and, for some states, nuclear weapons. The second is alliances, such as NATO, through which states combine their power against common threats. The third is disarmament and arms control, through which states try to limit the build-up of weapons and reduce the danger of war. The fourth is collective security, through which the international community, especially the UN Security Council, acts together against aggression.
A key idea in traditional security is the security dilemma. This refers to the situation in which a state's efforts to increase its own security, by building more weapons, are perceived by other states as a threat, leading them to increase their own arms. The result is an arms race, and all states end up less secure rather than more secure. The security dilemma helps explain the arms race between the USA and the USSR during the Cold War.
Since the end of the Cold War, the concept of security has expanded beyond military threats. Non-traditional security includes threats that do not come from the military power of another state but from other sources. These include economic insecurity, environmental degradation, health crises, migration, terrorism and civil conflict. The focus of security has also shifted from the state to the individual and the community.
The concept of human security focuses on the safety and well-being of individuals rather than states. Human security includes freedom from fear and freedom from want. It covers threats such as poverty, hunger, disease, natural disasters, violence and repression. The human security approach argues that the security of people is the ultimate purpose of security, and that a state that cannot protect its people from poverty and disease is not truly secure.
Some security threats are global in nature and cannot be addressed by any single state. Climate change, for example, affects the entire planet and requires global cooperation. Global pandemics, such as COVID-19, spread across borders and threaten the health and economy of all countries. Cyber threats and terrorism are also transnational. These global threats require a cooperative approach to security, in which states work together through international organisations.
Terrorism is the use of violence against civilians to achieve political goals. It is not a new phenomenon, but its scale and deadliness increased dramatically in the contemporary world, especially after the attacks of 11 September 2001. Terrorism is a non-traditional security threat because it does not come from a state's military but from non-state actors. Terrorist networks operate across borders, making them difficult to combat. The response to terrorism has involved military action, intelligence cooperation, and international agreements to track and freeze the finances of terrorist groups.
The spread of nuclear weapons to more states is a major security concern. The Nuclear Non-Proliferation Treaty (NPT) of 1968 was designed to prevent the spread of nuclear weapons, to promote disarmament, and to allow the peaceful use of nuclear energy. However, the NPT divides the world into nuclear weapon states and non-nuclear weapon states, and it has been criticised for not fulfilling the disarmament promises of the nuclear powers. Some states, such as India, Pakistan and Israel, have not signed the NPT, and North Korea withdrew from it. Nuclear proliferation increases the danger that nuclear weapons could be used or fall into the hands of terrorists.
India faces traditional security threats from its neighbourhood. India has fought wars with Pakistan and China and continues to face challenges along its borders. India has therefore maintained a strong military and has developed nuclear weapons for deterrence. India has also sought alliances and cooperation, such as the strategic partnerships with the USA, Russia, France and other countries, and its membership in groupings like the Quad.
India also faces non-traditional security threats. These include terrorism, especially cross-border terrorism in Jammu and Kashmir, cyber security threats, the challenge of internal insurgency and civil unrest, economic insecurity, and environmental problems such as air pollution, water scarcity and the effects of climate change. India's vast population makes human security a major concern, and the government has launched many programmes to provide food, health, education and employment security to its citizens.
India believes in cooperative security. It participates in UN peacekeeping operations, supports international efforts against terrorism, and cooperates on issues like climate change and cyber security. India has also pushed for reforms of international institutions and for a more inclusive approach to global security. India's approach shows that security in the contemporary world requires both national strength and international cooperation.
The future of security will be shaped by new and evolving threats. Climate change is likely to cause more conflict over resources, more migration and more humanitarian crises. Cyber warfare and artificial intelligence pose new dangers. Global health crises have shown how vulnerable the world is. The line between war and peace has blurred, and many conflicts are now internal or involve non-state actors.
The response to these threats requires a broadened conception of security that includes human security and global cooperation. States must work together through international organisations, share intelligence and technology, and address the root causes of insecurity, including poverty, inequality and political exclusion. The traditional tools of military power remain necessary, but they are not sufficient. A secure world requires justice, development and cooperation, not merely arms and alliances.

Security in the contemporary world is far broader than the traditional military conception of protecting the state from external attack. While military power, alliances and deterrence remain necessary, the sources of insecurity have multiplied. Non-traditional threats such as terrorism, poverty, disease, environmental degradation, migration and cyber attacks now endanger individuals, communities and states alike. The concept of human security has shifted attention from the security of the state to the security of people. Global threats like climate change and pandemics cannot be solved by any single country and require cooperative action. For India, security means defending its borders and maintaining deterrence, while also addressing terrorism, insurgency, poverty and environmental challenges. A secure world requires not just arms and alliances, but justice, development and cooperation among states and peoples.
