Advanced defence mechanisms for future network security using SDN

Abstract

Currently, the technology landscape is growing at a tremendous pace and new networking paradigms are emerging such as “Software-Defined-Network (SDN), Network-Function-Virtualization (NFV), Internet-of-Things (IoT), Industrial Internet (IIoT, SCADA), Industry 4.0, SDWAN, Software defined infrastructure (SDX), Internet Exchange Points (IXP), Software Defined Perimeter (SDP), M2M” and many more. Conventional network defence mechanisms are not sophisticated enough to overcome these challenges as they can detect only the rudimentary attacks, permitting attackers in exploiting the vulnerabilities in the modern network. In this paper, we proposed various novel secure and distributed SDN-based defence architectures for legacy networks, containing dedicated engines for traffic management, behavioural analysis and Anomaly detection. We have also conducted a comprehensive study of state-of-the-art defence mechanisms and frameworks that have evolved to resolve security problems of the future networks and our study compares the efficacy of our proposed defence mechanism.
