Just as the number of connected consumer "things" is increasing, so too are industrial "things" such as pumps, valves and remote terminal units. They get integrated into standard technology platforms, and connected to the Internet in pursuit of tantalizing operational efficiencies such as predictive maintenance and smart metering. This means that the operational technology (OT) in our manufacturing plants, power grids and water treatment facilities become vulnerable to threats faced by all other networked technologies, increasing the surface area of risk available to threats from bad actors. The delivery mechanisms for critical services become potential targets, from energy production, transmission and distribution to assembly lines and robotics. Many security technology overlaps exist between IoT and IT, however, IoT security involves monitoring physical devices, connections, authentication and data transfers at far greater volume than is common in IT today.
