Secure one-way interface for archestra data transfer

A system for transmitting ArchestrA information from a first network in a first security domain to a second network in a second security domain, comprising:

• a send server computer within the first security domain having an input coupled to the first network and an output, the send server computer configured to forward information received via the input on the output;
• a one-way data link having an input within the first security domain coupled to the output of the send server computer and an output within the second security domain;
• a receive server computer within the second security domain having an input coupled to the output of the one-way data link and an output coupled to the second network;
• a first stand-alone server computer within the first security domain coupled to the first network and configured to retrieve information via the first network from a first ArchestrA Galaxy in the first security domain and/or from a first historian in the first security domain and to forward the retrieved information to the send server computer via the first network;
• a second stand-alone server computer within the second security domain coupled to the second network;
• wherein the receive server computer is configured to receive the information from the send server computer via the one-way data link and to forward the received information to the second stand-alone server computer via the second network;
• wherein the second stand-alone server computer is configured to receive the information from the receive server computer and forward the information to a second ArchestrA Galaxy in the second security domain and/or to a second historian in the second security domain;
• and
• wherein the one-way data link is configured to transfer data only from the send server computer to the receive server computer and to prevent any signal from passing from the receive server computer to the send server computer, and wherein the receive server computer is coupled to the send server computer only via the one-way data link.
