Dynamic security of IoT network traffic using SDN

Abstract

Nowadays, smart environment has increasingly become a target for emerging cyberattacks that will impact the user's privacy and potentially, security. A remote attacker can illegitimately access connected objects in our IoT environment to obtain information about personal data or access control and availability of IoT objects, which can contribute to a DDoS attack. SDN (Software Defined Network) is a new paradigm that describes a network architecture whose control plane is completely decoupled from the data plane. The SDN concept offers the possibility of testing network functionalities before integrating them, without affecting the operation of the network. This minimizes the risk of network disruption. Our contribution in this paper is the design and implementation of a new type of architecture for securing exchanges in an IoT network using the SDN concept. The main objective of this work is to improve the quality and performance of this technology to ensure data reliability and avoid any type of internal or external attack by detecting the undesirable flow by Snort. This technology will also be used to organize and unify the management processes of all models based on SDN technology.
