Abstract
A multi-layer policy framework for monitoring and enforcing policy is provided. The multi-layer policy framework receives the desired state of the policy at each layer and translates the desired state into a realized state for the layer. The desired state specifies the intent of the user and the realized specifies the specific actions that have to be performed in order to reach the desired state. The realized state at each layer is sent to the next lower layer as the desired state for the lower layer. At the lowest layer, the desired state is converted into a realized state that includes a set of rules used to enforce the policy. The set of rules are then enforced at different enforcement points at the lowest layer.
