Distributed embedded firewalls with virtual private groups

This paper introduces distributed embedded firewall, a new architecture designed to counter the insider threat, which is undeterred by existing firewall implementations. The paper also describes virtual private groups, a group VPN technology. These technologies work together to addresses the security challenges of emerging technology. We describe the architecture and the rationale for its design, then we illustrate its application. The firewall technology has been transitioned from DARPA to the COTS 3Com Embedded Firewall.
