This project proposes a security management system called Moon. NFV uses cloud computing technologies to virtualize the resources and automate the control. The cloud infrastructure is able to provision a set of different cloud resources/services for VNFs (Virtualized Network Functions). Management of isolation and protection of, and interaction between, these VNFs become a big challenge. In order to avoid losing control over the VNFs in the cloud, Moon aims at designing and developing a security management system for OPNFV.
