E-Government Cybersecurity Modeling in the Context of Software-Defined Networks

Abstract

Currently, information and communication technologies are going in advance, allowing more information to be distributed globally via the internet superhighway. While being interconnected to the virtual world, people are becoming increasingly focused, large, and smart, needing the development of new solutions that will be implemented and robust network security systems. When the information is being handled in the applications, it is vulnerable to attack at every stage, and it is impossible to handle it in a separate manner, as traditional security systems have done. The introduction of software-defined networks (SDN) has provided a novel perspective on data security, since the network may assist in the construction of stable and safe continuity in the context of risks posed by the internet. The structure of SDN, particularly its gradual construction and centralization of network data and mechanisms, has pushed us to consider security from a strategy-practiced standpoint. The major goal of this chapter is to give detailed an overview of the current state-of-the-art in the area of SDN security and its significance in the context of e-government applications.
