Abstract A network security policy may be implemented at network switches as a set of active packet disposition directives. In a dynamically programmable network, the network switches can be dynamically reprogrammed with new packet disposition directives. A security mediation service permits such dynamic reprogramming as long as the new directives are consistent with the then-current network security policy. The security mediation service evaluates candidate packet disposition directives for conflicts with the currently active security policy, before instantiating the candidate packet disposition directives at the network switches.
