In this chapter, taking into account the complexity factor and multi-layered nature of the cloud, we present an automated cross-layer approach that tackles the above issues for auditing isolation requirements between virtual networks in a multi-tenant cloud. We focus on isolation at layer 2 virtual networks and overlay, namely topology isolation, which is the basic building block for network communication and segregation for upper network layers. To the best of our knowledge, this is the first effort on auditing cloud infrastructure isolation at layer 2 virtual networks and overlay taking into account cross-layer consistency in the cloud stack.
