The research method in this study has been based on positive paradigm and analytical-explanatory approach (Copenhagen School and its broad vision) to assess the challenges and their impact. The reason of choosing Copenhagen School as framework of this research is that this school, due to its security view to issues, provides context in which various security discourses can be discussed. Also, it should be noted that in the era of globalization, following the complexity of the threats, various security levels have been complicated and according to the researchers, this school has the ability to cover the various levels, as well.
