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.
Regardless, it can be agreed upon that SDN Controllers need to be highly protected, as it is a centralized decision point in SDN. Attacks on SDN Controllers mean compromising the network itself, as in SDN environments, the Controller acts as the “brains” and needs to be maintained.
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, SDxCentral will keep you up to date with the latest news, whitepapers, videos, and other resources on software-defined security.
