Enforcing security in semantics driven policy based networks

Security is an important requirement in scenarios such as mobile computing that allow users to make meaningful ad hoc collaborations. Traditional security solutions are not feasible for these scenarios due to the varying nature of the collaborations. We propose an extensible framework that takes the semantics of the collaboration into account and uses semantics driven policies for enforcing security. Our policies are rooted in semantic web languages which make them amenable to interoperability and high level reasoning. We describe our policy based network that exploits packet content semantics to secure enterprise networks and the BGP routing process.
