NFV and OpenStack
1) The document discusses network function virtualization (NFV) and how it relates to OpenStack. NFV aims to virtualize network functions through standard servers and storage to reduce costs and improve flexibility. (2) ETSI has defined NFV reference architectures, use cases, and an NFV management and orchestration framework. (3) The document outlines ongoing work by ETSI on NFV specifications and interoperability testing to advance the NFV ecosystem.

How does Openstack prevent back doors ? ? How does Openstack support secure boot, certified VM? ? How can I define security rules for an SDN application to change a flow table on an SDN switch that is provided by a IaaS Provider that may change along the life of the service ? ? How can I ensure that the memory I am sharing will not be accessed by somebody else ? ? Can I present the system admin to access my personal data etc Many blocks interact with Keystone Keystone is not the only entity that deals with security Keystone deals with security & policies, but NFV will need end to end security & policies across end to end network, at ?NFVO level : how to synchronize? etc
