Gigabit Data Diode copper in, copper out
- The GT-xxSD is a 1000Mbps Ethernet copper to copper data diode that assures one way data transmission across a fibre link. A totally hardware based solution the CF-xxSD is a Layer 1 device and operates at wire speed for optimal performance. Desktop or rack-mountable the GT-xxSD takes data security to new levels.
- Guaranteed one way transmission
- No physical return path
- Totally hardware based solution with optical separation/partition between input/outputs
- Tamper proof casing
- Independent power supplies for both High and Low side
Why do I need a data diode ?
Data diodes play an integral part in securing the most critical business assets, protecting the most valuable data and ensuring operational continuity.
The physical nature of a data diode ensures data can only ever flow in one direction. Typically they are deployed at the boundary between a high security environment and a lesser network, data diodes stand guard at this intersection where unrestricted two-way communications would otherwise increase the risk of malicious attack and data loss.
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.
