BLOG: 4 ways network virtualisation improves security

Rod Stuhlmuller | Dec. 20, 2013
Network virtualisation is not only essential to a mature cloud infrastructure, it also beefs up security, argues VMware's Rod Stuhlmuller.

Traditionally, this level of network security would have forced network and security teams to choose between performance and features. Leveraging the ability to distribute and enforce the advanced feature set at the application's virtual interface delivers the best of both.

The infrastructure maintains policy, allowing workloads to be placed and moved anywhere in the data center without manual intervention. Pre-approved application security policies can be applied programmatically, enabling self-service deployment of even complex network security services.

As more data centers adopt network virtualization and move toward the software-defined data center, we'll see a broad range of traditional security solutions that leverage the unique position of the network virtualization platform in the hypervisor. Detailed knowledge of VMs and application process owners, combined with automated provisioning speed and operational efficiency, is the foundation for an exciting new approach to some very old challenges.
