Data diode for rail simplifies mission-critical Ethernet

Industrial security can be simplified with the latest unidirectional Ethernet network appliance from Belden.

The Hirschmann rail data diode secures mission-critical Ethernet networks through guaranteed one-way data traffic, while also transferring data out of the secure part of the system in a controlled, deterministic manner, explains Belden.

“Effective supervision requires access to data without putting the system at risk to cyber threats,” said Rolf-Dieter Sommer, product manager at Belden. The Hirschmann rail data diode can be used by industrial organisations to improve overall operations and control. It can also be used to protect networks from external cyber threats through singular data flow, by securely transferring Ethernet data to the public internet without putting the system at risk.

The rail data diode can be used in applications where data from mission-critical systems must be transferred via the public internet and industries with vital applications such as critical infrastructures in transportation, power and chemical plants.

As an early innovator in industrial Ethernet, Belden specialises in industrial IT and delivers industrial networking solutions, including wired, wireless and embedded products.

Products from its global brands – Hirschmann, GarrettCom and Tofino Security – help companies minimise downtime and take advantage of the real-time data access and control made possible by the industrial internet of things (IIoT).
