초록

전 세계적으로 국가경쟁력, 효용성, 중요성 등의 이유로 메가시티가 속속 등장하고 있으며, 점차 각 국가의 중심지로 자리를 잡아가고 있다. 또한, 메가시티는 현존, 잠재적, 초국가, 비군사 등 다양한 위협에 노출될 수밖에 없다. 특히, 최근 우크라이나-러시아 전쟁에서 볼 수 있듯이 국가기반체계는 적대 및 위협세력의 주요 목표가 되고 있다. 하지만 메가시티의 막대한 규모, 다양한 위협의 양상, 한정된 자원 등을 고려할 때 모든 국가기반체계를 완벽하게 방호하는 것은 현실적으로 어렵다. 따라서 여러 국가기반체계 중 핵심노드를 식별하여 중점적으로 방호하는 접근이 필요하다. 핵심노드는 다양한 국가기반시설이 연결된 국가기반체계의 중요도가 매우 높면서도 동시에 급소에 해당한다. 이를 위해 본 연구에서는 핵심노드를 논리적·체계적으로 식별하기 위해 네트워크 이론인 노드 중심성(Centrality) 분석방법과 군사이론인 중심(Center of Gravity) 분석방법을 제시하였다.

Megacities are emerging all over the world and gradually becoming the center of an country. Therefore, Megacities are inevitably exposed to various threats such as existing, potential, supra-national, and non-military. In particular, as seen in the recent Ukraine-Russia war, national infrastructure systems has become a major target of enemies. However, considering the size of Megacities, various types of threats, and limited resources, it is impossible to completely protect all national infrastructure systems. Therefore, wisdom is necessary to identify and protect critical nodes. The critical node is the vital point to which the national infrastructure is connected. To this end, in this study, as a method for logically and systematically identifying critical nodes, Node centrality analysis method, which is a network theory, and the Center of Gravity analysis method, which is a military theory, were presented.
