What’s Next For Network Security (Dark Reading)

Network security as we know it ultimately will operate hand in hand with software-defined networking (SDN) and virtualization, security experts here said.

SDN could be a game-changer like virtual machines were, says Cameron Camp, a security researcher at ESET, “If you understand it and know how to do the hard work of network security, you’re going to do better with SDN,” he says.

It’s a logical evolution: as the network and its services become more software-driven and virtualized, it only makes sense that security would join the party. SDN is an emerging network architecture that is becoming popular in data centers.

But a software-defined network architecture comes with some security risks of its own. It leaves organizations open to internal distributed denial-of-service (DDoS) attacks, says Camp, who in a presentation here tomorrow will show how malware can enter virtual environments. It’s possible to hack a virtual machine and basically “blow up that whole box and the network with it,” he says.
