Enabling safer more resilient infrastructures
The Internet of Things (IoT) is set to benefit society through a range of smart platforms and has been undergoing huge expansion; estimates vary but it is in the order of tens of billions of devices and growing rapidly. The focus of this review is the Industrial IoT (IIoT). IoT-enabled industrial control systems (ICS) are becoming a significant proportion of current and future critical infrastructures, with high uptake in areas like energy, transport, the built environment and manufacturing facilities. The consequences of failure can be high in these environments and so it is essential to understand how to deliver secure and resilient infrastructures. The IIoT exacerbates security challenges that already exist and poses new ones of its own. It is essential to prioritise action by identifying key emerging risks and gaps in capability.
From a security standpoint, this review considers the IIoT to be comprised of three key parts: physical devices (especially including sensors), communications networks, and information and data, including associated software and hardware technologies for delivering processing and analytics.
