  • Tamper proof casing
  • Independent power supplies for both High and Low side

 

Technical Notes

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.
