Industrial companies are increasingly implementing the Internet of Things (IoT) on the factory floor and in the field. Such largescale end-to-end Internet Protocol (IP) connectivity will doubtless facilitate many more capabilities at the edge of these networks, but at the same time, it presents a huge security threat. IIoT enabled Operations Technology (OT) offers a much larger surface prone to cyber-attack than the IT space where by comparison the volumes of data are lower and its comings and goings can be more precisely controlled.
In the industrial sector, huge amounts of data are being processed at the edge and sent back to the cloud for further analysis and used by different applications. These applications as well as the operating systems they reside on, communicate with physical devices through device drivers and firmware. Attackers can exploit these special classes of software to subvert and compromise hardware. Every single device and sensor in the IoT represents a potential risk but today significant numbers of IoT devices are not being used with security in mind. Many are easily available for physical access.
