Title: One step removed shadow network

Abstract

A system and method includes an operational network that communicates with an external network by opening a first transmission protocol socket. A data diode coupled to the operational network and a gateway enables the one-way transfer of all information received from the external network and transmitted by the operational network to the gateway such that no information travels from the gateway to the operational network or the external network. The gateway opens a second transmission protocol socket by mapping a sequence number to an acknowledgement number and increasing that mapped acknowledgement number by a value of one. A transmitter then transmits the acknowledgment to a remote network or a gateway.
