Abstract
A reference monitor (RM) operates within a network having controllers that each control a corresponding network part having a forwarding element (FE) for forwarding data within the network. The RM enforces the security policy for a first network part managed by a first controller. The method includes: receiving a first rule request from the first controller, checking the first rule request for policy compliance, authorizing a part of the first rule request that is policy compliant, receiving a second rule request, the second rule request being from a second controller configured to control a second part of the network, the second rule request comprising an outside modification impacting the first network part, which is not managed by the second controller, checking the outside modification part for policy compliance, and based on determining that the outside modification part is policy compliant, authorizing the outside modification part of the second rule request.
