The Network Pump® is a Government off-the-shelf (GOTS) High Assurance “One-Way” Guard that enables applications operating on a lower security level network to pass information to applications on a higher security level network automatically. Developed by the U.S. Naval Research Laboratory (NRL), Center for High Assurance Computer Systems, the “One-Way” Guard delivers information without leakage from the High network to the Low network.
Assured Delivery: As part of this transfer, the application on the Low side receives a meaningful acknowledgement that the information has been delivered to the High network. Most competing “guarding” technology solutions do not provide this type of acknowledgement. The Network Pump® implements a NRL-patented algorithm that statistically modulates the delay of the acknowledgement to mitigate the potential for covert timing channels.
Network Transparent: The Network Pump® works with any operating system on any hardware platform that supports a TCP/IP network. NRL provides the pump protocol used for packaging data for transfer to and from the Network Pump®. In addition, to support specific files types and acknowledgements between systems across the boundaries, relays have been developed to execute the pump protocol for data file transfer.
