Directory File Transfer System (DFTS)
Secure DFTS Application
Secure Directory File Transfer System (The Secure DFTS) supports secure and reliable one-way file-based communications. The Secure DFTS consists of intuitive send and receive application programs built on our exclusive DualDiode® technology to support reliable, high speed (155 Mbps) one-way transmissions. Our patented DualDiode technology consists of send-only and receive-only communication cards connected with a single fiber optic link and custom device drivers that are independent of existing TCP/IP communications. These components reside in rack mounted Windows 2000 / Windows 2003 / Windows 2008 / Vista / Windows 7 workstations or servers.
How it Works
Data can originate anywhere on the non-secure network and be moved into files and subfolders within a designated directory of the source or “blue” machine. The Secure DFTS will transfer, or mirror, the information from the blue machine across the one-way data diode link to the destination, or “red” machine. No information of any kind, including handshaking protocols (as in TCP/IP, SCSI, USB, Serial/Parallel ports, etc.) travels from the destination computer back to the source computer. This “trust nothing” design ensures that data residing on the isolated LAN is fully protected.
Our turnkey solution provides color-coded Blue (send-only source) and Red (receive-only destination), rack-mounted machines tested with the software, hardware, and communication drivers preinstalled. This includes hardware for "send-only" and "receive-only operations, the communication drivers, and Secure DFTS send and receive applications.
