Changing the concept of national security in the post-Corona world

It has been more than a year since the onset of the corona pandemic. During this time, the spread of Covid-19 disease has severely affected economic, social, and psychological security. Most countries had secured themselves against security threats by acquiring significant military and nuclear capabilities and membership in military and economic blocs and complexes, but now, with the outbreak of the disease, they have failed to save the lives of their citizens and are facing national security problems. Therefore, by recognizing and understanding the changes that have taken place accurately and in a timely manner, they can identify new components of national security, find ways to access them and provide new security, and take the best steps to protect and enhance the interests of their people. The main purpose of this study is to identify the conceptual components of national security in order to provide theoretical assistance to the field of security policy for effective security management in the future.In this study, the documentary method was used to collect data and the model designed by the authors was used as the basis for data analysis. The findings of this study indicate that the proper functioning of governments requires: a review of security and defense policies, a greater focus on managing international crises and disasters, and a review of the role of government in overseeing the provision of basic services.
