I  cover a recent white paper from the Cloud Security Alliance about network function virtualization (NFV) in a series of posts for IBM’s SecurityIntelligence.com blog. In the first post, “Security and the Virtual Network: Part I,” I discuss how NFV and software-defined networks (SDNs) are changing the traditional enterprise infrastructure. Part two explored some security challenges and implementation risks involved with deploying new virtual networks and their related technologies. And in the third post, I recommend improvements and certain security frameworks for protecting your virtual networks.

Virtual networks’ dynamic nature means IT staff have to take time to document its topology and data flows carefully and keep up with any changes to its structure.
