Internet of Things security concerns using SDN: An overview of theory and research

Thair A. Salih , Abdulrasul A. Samad

Abstract

The International Telecommunication Union (ITU) defines the Internet of Things (IoT) as a collection of physical objects that may be integrated with and controlled by wireless communication networks. The IoT) is currently a popular technology due to its numerous applications. It consists of a large number of disparate devices that are linked together via the Internet, and it is difficult to regulate and protect these devices. SDN, short for Software Defined Network, is a new networking paradigm that simplifies network management and encourages network growth while also making it easier to create and introduce new abstractions in networking. One day, IoT will permeate every aspect of our life and be available everywhere, so security is more essential than ever. IoT devices must be able to react dynamically to various threats, requiring a new approach to security and protection. To achieve this, SDN will be a vital component in enabling IoT devices to be intelligent and secure. This study aims to emphasize the literature focusing on the security issue in IoT, which gives a brief introduction to SDN technology and provides a taxonomy and survey of the current state of IoT security research based on SDN technology.
