As awareness of the transformative nature of 5G is increasing, the industry is slowly waking up to the enormous challenge of securing not only the networks but also all the things these networks connect and the vital data they carry. When it comes to the Internet of Things (IoT), the challenges of security and the stakes involved couldn’t be more significant. The spread of IoT in homes, enterprises, industries, governments and other places is making wireless networks the backbone of the country’s critical infrastructure. Safeguarding it against potential threats is a basic need.
IoT modules, being at the heart of IoT devices, are fundamental to the system security. Unlike smartphones, modules are simple and very vulnerable to intrusion. Any compromised module exposes the entire system and puts it at risk. Hence module security must be comprehensive, including the device hardware, software, firmware and management system (a.k.a., cloud platform) that facilitate ongoing operational security throughout the device lifecycle. The responsibility of securing the IoT modules typically falls on the shoulders of module vendors, as many IoT device vendors and users may not have the expertise or the means to access and secure the module themselves. This paper examines the comprehensive security needs of IoT modules and platforms and discusses the best practices to ensure that the whole system is protected.
