The industrial routers mbNET.rokey enable secure access to machines and plants via the Internet. There are two application cases with different requirements: data acquisition and remote maintenance. During data acquisition, data supplied by the plant are continuously recorded.
Remote maintenance only takes place when required – for example for an update of the PLC program. This requires active access with routing to controllers and other components. From the cybersecurity point of view, the areas of attack here are much larger than in data acquisition.
To limit the risk the operating staff can use the integrated key switch directly on the router to control when remote maintenance is permitted. Permanent online connections for remote maintenance have long been a thorn in the side of many plant operators. With the key switch, this topic is done. The plant operator decides directly at the system about connection is available.
