Logical Network Boundary Controller

The current, dominant approach to implementing secure boundary controls across networks relies on strict physical separation of networks. The approach of using trusted operating system platforms and automated guards has proven to be unworkable for multimedia applications and cost prohibitive for most civilian environments. Architecture Technology Corporation (ATCorp), in collaboration with the University of Minnesota, is developing a technology called Logical Network Boundary Controllers (LNBC) that will effectively distribute information to multiple security level users across multiple physical networks without compromising the security of the data. The technology will facilitate secure cross-domain collaborations for both synchronous (e.g. audio/video conference, chat) and asynchronous (e.g. document sharing, email) applications. The COTS-based technology will provide a low-cost solution to cross-domain information sharing in a variety of digital media for Homeland Security as well as other civilian operations.
