Nexor Data Diode is a hardware device designed to physically enforce unidirectional data transfer between networks, ensuring isolated domains can share information without the risk of bidirectional communication. The device operates by using a single strand of a fiber optic connection alongside specialized optical processing electronics, which physically prevents data from leaking back to an untrusted source network.
To manage data transmission without bidirectional protocols like TCP/IP, the system utilizes upstream and downstream proxy servers that transmit data in a connectionless manner. These proxies facilitate a protocol break through "catcher" and "thrower" components, which strip traffic control data and securely pass only the payload, thereby neutralizing malware infiltration, data exfiltration, and command-and-control threats.
