Despite its many foreseen benefits, the main barrier to adoption of cloud computing remains security. Vulnerabili-ties introduced by virtualization of computing resources, and unclear effectiveness of traditional security architectures in fully virtualized networks raise many security challenges [5]. The most critical issue remains resource sharing in a multi-tenant environment, which creates new attack vectors. The question is thus how to guarantee strong resource isolation, both on the computing and networking side. System and network complexity make manual security maintenance im-possible by human administrators. Computing and network-ing isolation over virtualized environments should thus be achieved and automated. Unfortunately, current solutions fail to achieve that goal: hugely fragmented, they tackle the problem only from on
