Abstract
A system and method of achieving network separation within a computing system having a plurality of network interfaces. A plurality of burbs or regions is defined, wherein the plurality of burbs includes a first and a second burb and wherein each burb includes a protocol stack. Each of the plurality of network interfaces is assigned to one of the plurality of burbs and more than one network interface can be assigned to a particular burb. Processes are bound to specific burbs when they try to access that burb's protocol stack and communication between processes assigned to different burbs is restricted so that a communication between a process bound to one burb must pass through a proxy before being sent to a different burb.
