Data Diodes
A data diode is a unidirectional network communication device that enables the safe, one-way transfer of data between segmented networks. Data diode design maintains physical and electrical separation of source and destination networks, establishing a non-routable, completely closed one-way data transfer between networks. Data diodes effectively eliminate external points of entry to the sending system, preventing intruders and contagious elements from infiltrating the network. Securing all of a network’s data outflow with data diodes makes it impossible for an insecure or hostile network to pass along malware, access your system, or accidentally make harmful changes.
