Rockwell Automation – The JOURNAL Article: “What are Data Diodes?”


Learn how and why these one-way devices are increasingly being used to help protect industrial networks against common cybersecurity vulnerabilities.

Cyberattacks increasingly have made news headlines around the globe. Recently, the New York Times published an article about a cyberattack earlier this year that involved Russia’s hacking of utilities and critical infrastructure. Though some infiltration did occur, this solely and specifically was on the network side, leaving operations untouched thanks to a hardware-enforced security technology called a data diode.

The risks, and subsequent strategies to fight these attacks, constantly are changing.  Data diodes are one such strategy used to counter cyberthreats. This one-way technology protects against common network vulnerabilities. Here, we’ll take a closer look at how they support cybersecurity.
