Network functions virtualization is all the rage because of the money it can save, and because of the network flexibility it helps afford, but the cable industry is enthused about NFV for yet another, less publicized benefit: the potential NFV creates for improving network security.
"We're looking at SDN and NFV, and how those technologies can potentially mitigate some of the problems, and be used to put in multiple layers of defense," said CableLabs' Principal Architect for Security Steve Goeringer. (SeeCableLabs Sets Up NFV Interop Lab.)
Should hackers find a vulnerability they can exploit, and once a network operator detects it, the operator can implement countermeasure quickly and system-wide, if the network is based on SDN and NFV, Goeringer explained.
