As software-defined networking (SDN) environments continue to grow, security is essential to protecting the availability and privacy of all connected resources and information, but securing SDN can be difficult. Conflicting views about where security is best placed has some arguing it should be embedded within the network, while others believe security should be in the servers, storage, and other computing devices.
A shift to next-generation environments has created a new category: software-defined security. An example of network functions virtualization (NFV), software-defined security provides a new way to design, deploy, and manage networking services by decoupling the network function from hardware appliances. Created to consolidate and deliver networking components necessary to support a virtualized infrastructure, software-defined security includes virtual servers, storage, and even other networks.
As new methods and protocols are created to better protect SDN environments, security resources from SDxCentral will provide helpful information about evolving strategies.
