An Attack Analysis Framework for LoRaWAN applied Advanced Manufacturing

Advanced manufacturing is transitioning into automated production, which enables the remote system monitoring, increases the online system configuration, and thus reduces the overall cost on workforce. However, the remote access to production plants makes advanced manufacturing vulnerable to various security attacks from physical devices to cyber space. The traditional assumptions on the security of manufacturing plants do not hold true any longer. It is imperative to perform holistic assessment on the emerging security vulnerabilities in advanced manufacturing network. In this work, we propose an attack analysis framework to enable the comprehensive assessment on the potential attacks that challenge the advanced manufacturing factories. As the long-range wide-area network (LoRaWAN) is commonly applied in advanced manufacturing sites, we examine the security weaknesses in commercial LoRa nodes, gateways, and LoRaWAN connection in this work. Jamming attack, replay attack, and man-in-the-middle attack from physical and cyber access are analyzed in this work. The security vulnerabilities disclosed from the proposed framework have great potential to facilitate the development of effective defense methods for advanced manufacturing industries in future
