Most data diodes accomplish the one-way limitation by a fiber-optic network link, with the send and receive transceivers removed or disconnected for one direction. Some products also include software in order to authorize and allow only certain types of trusted communication.
In this Data Diode Comparison Guide we compare the different data diode offerings to help you decide which product suits your organization best. For each data diode, we list a number of product attributes to allow for easy comparison.
Support for Antivirus
Since data diode traffic is unfiltered, it is important to add antivirus to ensure that the data diode traffic is scanned for malware. For each data diode we specify whether they offer a single antivirus solution, and whether they offer the option of multiscanning with multiple antivirus engines for the highest protection.
Integration with Portable Media Kiosks
In addition, the guide lists whether the data diode can be used with a portable media malware-scanning kiosk to transfer clean files into the secure area, avoiding the need to bring in removable media. Some data diodes offer additional secure file transfer functionality to ensure that only authenticated users and guests can retrieve their files in the secure area.
