Industrial control networks, e.g., for factory, process or energy automation and smart metering, are increasingly based on IT communication technologies like Ethernet, IP, and Web-Services. Security measures as authentication or cryptographic VPNs are used to protect communication links to supervising control stations and for remote service. While standard communication technologies have been used at the supervision level for some time, they will increasingly be used down to the field level comprising a huge number of field level control devices, sensors and actuators. These may be installed in largely distributed, uncontrolled areas.
