Security policy unification across different security products

A management entity receives from multiple security devices corresponding native security policies each based on a native policy model associated with the corresponding security device. Each security device controls access to resources by devices associated with the security device according to the corresponding native security policy. The management entity normalizes the received native security policies across the security devices based on a generic policy model, to produce a normalized security policy that is based on the generic policy model and representative of the native security polices.
