The internet of things and Industry 4.0 networks require reliable, safe, and secure data links. However, these days, any network is prone to cyberattacks even when secured by traditional security methods. To solve this issue, the data diode, a hard- and software device, allows only data uploads to the external world and avoids, for security reasons, any backward data downloads.

The cyber-diode extends the capabilities of traditional solutions for network security. The importance of safe and secure networks is proven by a study on cyberattacks conducted by the Bundesamt für Sicherheit in der Informationstechnik (BSI or, in English, German Federal Office for Information Security). According to the study, the amount of malware, including Trojans, ransomware, and trickbots, increased between June 2019 and May 2020 to 117 billion, with the variations and intensity of the malware continuing to rise. The requirements for optimal security in the interconnected industry and in critical infrastructures are very high, and industrial equipment interfaces must be fully protected to avoid any negative impact. Another important point is that the data transmitted must be confidential and non-manipulable.

"But even with existing security solutions, there is still a remaining risk," Steve Schoner, strategic product marketing manager of Genua GmbH, told EE Times Europe. "With the cyber-diode, we are closing this gap." Genua GmbH, founded in 1992, is a business unit of Bundesdruckerei (German Federal Printing Office). It has extensive experience with private entities handling classified information and is specialized in protecting any network and digital communications.
