IoT Security System Based on Software Defined Network with Manufacturer Usage Description

Abstract

In recent years, the advancement of the Internet of Things (IoT) has significantly improved convenience; however, it has also increased security risks. Due to resource constraints, IoT devices have limited functionality, making it difficult to implement robust security measures. Additionally, users of home networks, one of the primary application areas of IoT, generally lack security expertise. Therefore, it is essential to develop a security system that meets the requirements of IoT devices while minimizing the burden on users. In this study, we propose a system that applies Manufacturer Usage Description (MUD) to home networks to define and control IoT device communication. This approach enables security measures to be implemented on IoT devices while reducing user burden. Furthermore, the proposed system monitors network traffic and isolates compromised devices upon detecting an attack, thereby minimizing potential damage. Through simulation based evaluations, we demonstrate that the proposed system effectively maintains security requirements.
