A Secured Software Defined Network Architecture for Mini Net using POX Controller

Abstract

SDN (software-defined networks) is a new technology that stems from numerous network security enhancements. It handles network data in a flexible manner using highly secure frameworks. The secure SDN model's purpose is to ensure data security. The proposed idea to be executed is a robust firewall protection in a mini net employing a POX controller. In order to deal with network-induced dangers, the huge network connectivity influenced environment requires additional protection. The proposed effort focuses on creating a secure SDN simulation architecture that is managed by Open Source POX Controller. Through a POX-controlled traffic management system and a Fingerprint-enabled authentication technique, the system provides multilayer security. The enhanced security is achieved by assessing network traffic as either elephant or mouse flow and selecting the appropriate security level based on data complexity. Mininet is run in a virtual cloud, where protocols and tools are tested and supported by a virtual machine (VM). The novelty is to produce a secure SDN topology was created using a python-based POX controller in the suggested technique. It also provides a low-cost solution as well as rapid development in conjunction with industrial networks.
