ABSTRACT
This chapter focuses on the changing nature of the concept of security border in the light of ideas of both critical and post-positivist security thinking that is the Post-Cold War security border. It presents the notion of security border reflecting its construction and underlying assumptions and the ideas based on so-called new security thoughts, that are the critical school and postmodern orientation, and how they see the notion of security border. The chapter discusses the traditional school of thought meaning the orientation of political realism of the discipline of international politics. The intention to control the development of certain territory and particularly its security aspects denotes that by certain means an attempt is made to manage both the problems already existing and those to come. Security border is a construction of the human mind - and therefore changeable. The chapter concludes with thoughts on the present development within an integrating Europe, and particularly on the security border concept.
