Overview
The GT-xxRD is a 1000Mbps Ethernet copper to coper data diode that assures one way data transmission via unidirectional fibre links. A totally hardware based solution the GT-xxRD is a Layer 1 device and operates at wire speed for optimal performance. Desktop or rack-mountable the GT-xxRD takes data security to new levels.
Technical Notes
What is a data diode?
'A data diode is a cybersecurity device that ensures data can only flow in one direction'. This article explains how data diodes work and where they can be used.
Configuring ARP for use across Data Diodes
Address Resolution Protocol (ARP) is a protocol used to ascertain the hardware address or Media Access Control (MAC) address from an IP address. Typically a sending station knows the destination IP that they wish to send to but does not the MAC address. Before communication between the 2 hosts can occur an ARP request is sent to discover the destination MAC address. The ARP request is directed to the destination IP address using a MAC broadcast address FF:FF:FF:FF:FF:FF. All devices on the subnet receive this broadcast but only the destination with the correct IP address will respond.
