The defense industry is the most significant part of our country�s defensive capabilities not only as a matter of the nation�s pride but also during the times of threats. The most essential role of national security is protecting all its citizens, infrastructure, economy, and institutions. Initially, national security was referred to as just security against the military attacks. But in recent times, its core definition has changed and now, it also includes energy security, cyber security, environmental security, food security as well as economic security. National security threats also include multinational corporations and even the effect of national disasters that are combated with the help of the other nation states.

Protecting the security of our nation from internal as well as external threats to our social and political system is the primary aim of political security. The goal of economic security is not only protecting the economy that is offered to the people, but also the degree to which the government and its people are free to manipulate their economical as well as financial decisions. Economic Security also facilitates removing inequality in the incomes of the people and eradicating poverty in the nation.

Initially, when the concept of environmental security was included in global security, it usually included reacting to the conflicts that are traditionally caused by environmental problems like water shortages and energy disruptions. But its core meaning has changed over the recent years and it now includes protecting the environment and the climate as well. Environmental degradation over the years has risen because of humans themselves and it has become very important to address these issues through international policies and treaties. Even though the threat of natural disasters wasn't included in environmental security, the ideology has changed because of global warming and severe climate changes due to environmental degradation.

Global security is a collection of ideas, largely developed by the United Nations. The world�s security is everyone�s business. This means that no single nation will be safe and secure unless almost all are secure. We mainly focus on eliminating conflict through international aid, law, global governance, and confidence-building measures. Thus, the use of force must be reserved for peace enforcement, peacekeeping, and protecting innocent citizens from the violence. Today, Global Defense News has come to offer different people different things. As said earlier, there are different kinds of national securities available these days. Even, security is offered for our health, women, and food along with energy, environment, and our economy too .

Human security is a huge concept to encompass people�s safety from disease, repression, hunger, and other harmful disruptions of everyday life. Ultimately, the concept gets expanded with an intention to include food security, environmental security, political security, economic security, personal security, health security, community security and the defense of women and other minorities. Its unique character is to downplay or avoid national security because military problems rise between nation-states rather than focusing on economic and social causes. So, it is determined to be an assumed international responsibility for protecting people from violence.

The collective defense as a concept has been developed as an arrangement to fight collectively and provide a defense to any of the member states when they are attacked. This is an official arrangement which focuses primarily on military power and they are not just differentiated on the basis of geographical limitations. Collective security, in a general sense, involves collective mutual commitment between the member states although it is geographically limited to military defense. This concept is said to be originally represented by international peace institutions like the United Nations and the League of Nations and it has taken shape with the development of technology over the years.

Actually, if you focus on achieving everything, then you will produce positive results for a few things. National security is far more than just the standard and situation of our nation�s security. It also related to the activities and policies Carried out by the government. This point should be well noted and understood by the Department of Defense and Armed Forces with great importance. It is essential to recognise what national security is and going through national Security news and then, establishing a clear list of occurrences for what constitutes a threat to our national security is the best way to do so.
