Although the Internet of Things (IoT) has enjoyed explosive growth in recent times, it’s still a relatively recent concept. It is based around the idea of connecting any devices or objects that incorporate electronics, software or sensors, with the aim of collecting and exchanging data. Over the past few years, IoT has spread like wildfire, and shows little sign of slowing down. However, the component manufacturer Omron points out that this rapid increase in the number of devices or end points for the Industrial Internet of Things (IIoT) also means that there is a correspondingly higher risk in terms of security.
