Due to the revolutionary impacts of global developments in the world, there is an intense debate on the change of power and security concepts. The concept of security, which is one of the greatest discussion topics of academics researching in the discipline of International Relations, although in traditional theories it is mostly identified with the state, today this concept is evaluated from a wider perspective. This conceptual change also leads to questioning the function of the state in the field of security. This study aims to bring a concrete and comprehensive understanding of how the built-in security perception develops in the national state axis. In this context, the focus is on how the concepts of power and security are perceived in the framework of changing world dynamics. While a new concept is discussed how security culture has changed the sense of security as an external impact of global developments, a comprehensive explanation of the impact of new types of threats on the traditional sense of security is being made. Contrary to crisis and conflict-based discussions, food, health, migration, and transnational terrorism are addressed to the different dimensions of the security culture and how small non-governmental forces overthrow the power of the national state and how national security is structured in the traditional theories of international relations. The indicated aspects of security can be pointed out that the capacity of the national state is weakened, but it is achieved to the conclusion that it can strengthen its power using various methods as it does not come to a strong structure as it does. At the end of the day, it is estimated that the national state has not lost its ability to influence the exercise of power and security culture and, on the contrary, has reactivated it.
