Cloud slicing allows the existence of multiple virtual infrastructures, called virtual slices, on top of the physical infrastructure of federated data centers, each one specially adapted to the needs of the tenants. Although cloud-slicing makes services and networks more agile and responsive to users' business requirements, it adds new security concerns because of how physical resources are shared between slices and how isolation is held. Therefore, the purpose of this work is to propose a methodology to increase security levels in federated cloud platforms defined by resource slices, which exploits virtualization technologies to enable secure resource sharing and isolation, management of heterogeneous security policies, and the provision of risk mitigation actions using the Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) technologies.
