De-Militarized Zone: A Next Level to Network Security

Abstract

In recent years, due to rapid enhancement in computer technology, network security has become a big concern for any organization. As a result, most of the organizations are investing billions of dollars every year to get strengthen their network infrastructure. Now, when we look into this problem, one of the possible solutions which can be thought off as is to implement industrial level De-Militarized Zone. The De-Militarized Zone is a process of building up a semi-secure network which works as the first line of defense to protect the internal infrastructure of any organization from external threats. By implementing this small and efficient technique, many network security problems can be resolved at first sight. This paper provides an insight view of different levels of DMZ design and based on these design levels, a small DMZ model has been proposed to enhance the internal security of an organization keeping common network security problems in mind.
