Network Pump®: High Assurance "One-Way" Guard

Description:

Overview: The Naval Research Laboratory (NRL) has developed 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 NRL's 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 if 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 an 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 as 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 file types and acknowledgements between systems across the boundaries, relays have been developed to execute the pump protocol for data file transfer.
