This Space Intentionally Left Blank

Presented at DEF CON 12 (2004), July 31, 2004, 3 p.m. (50 minutes)

"This Space Intentionally Left Blank" covers work done to safely allow the transfer of unclassified data onto a sensitive (read highly classified) network for comingling with other data collects and subsequent analysis. We devised a system using COTS (Commercial Off The Shelf) hardware, Open Source applications and a couple of custom programs to accomplish these ends. The main requirement was to ensure a one way flow of data from the antenna farm into the analysis network with no data drift back. The presentation will discuss the technical details of how this was managed.
