The study aims to analyse the connection among types of security intimidations: threats, challenges, vulnerabilities, and security risks, to establish the rapport between national and global threats, to review critical issues of the security environment.The study’s relevance is that the concept of security needs to be updated in the current changes in the global security context and the emergence of an increasing number and variety of threats under the transformations that are taking place. The research shows how the reconceptualization of security in the late twentieth century was influenced by global contextual changes associated with the end of the Cold War and the use of constructivist approaches in the social sciences. This dual change has led to a rethinking of security challenges in the second decade of the 21st century, leading to increased interest in this study. It is exposed that the concepts of vulnerability and risk are used not only in the context of foreign and defence policy, but also concerning ecologic security challenges caused by global environmental change, climate change and dangers and disasters, where there is no consensus within and among the community on vulnerability, and risks. In conclusion, it is proved that conceptual thinking on security threats has necessitated precise definition and consensus on these concepts, especially on practical policy measures to achieve agreed goals, and systematization of types of threats to all types of security and life support. It is determined that the degradation of traditional political institutions, against the background of the degeneration of the established international law system and order, cause the emergence of new threats to national security and, accordingly, political, as its subcategories. It is noted that modern researchers have paid little attention to studying the connection between the concepts of political security, state security and threats to state security. In the context of new globalization threats, states are facing a change in the security context and need to review security strategies and update the discourse on political and national security.
