Abstract
A system includes a first processing circuit, a second processing circuit, and a network interface device. The network interface device includes a first communications interface, a second communications interface, and a filtering engine. The first communications interface is configured to receive first data packets from the first processing circuit and communicate the first data packets for transmission to the second processing circuit via a first network pathway. The second communications interface is configured to receive second data packets from the second processing circuit and communicate the second data packets to the first processing circuit via a second network pathway physically separated from the first network pathway. The filtering engine is configured to determine whether the first data packets satisfy an inspection criteria, and transmit the first data packets to the second processing circuit responsive to determining that the first data packets satisfy the inspection criteria.
