Software Defined Networking (SDN) = Security [VIDEO]

Among the biggest security trends that emerged in 2015 is the idea of network micro-segmentation with software defined networking (SDN). The basic idea is to slice up a network into small pieces that contain and isolate specific networking functions and applications.

Among the leading proponents of using SDN to improve security is networking vendor PLUMgrid, which offers an SDN solution for OpenStack cloud deployments. In a video interview, Larry Lang, CEO of PLUMgrid, explains why SDN equals security in the modern world.

SDN micro-segments can help to limit the risk of a single breach from being an even bigger and more widespread breach, much like the way bulkheads work in a boat, Lang explained.

It's the same basic approach that all public cloud providers employ, by treating each application as its own tenant. In a public cloud, one tenant doesn't speak to another without explicit permission. That way if there is a breach in one of those areas, it doesn't automatically spill over into the entire cloud.

"SDN equals security; it's not the only thing it equals but for the people spending money, security is top of mind," Lang said.
