Securing Software Defined Networking

Abstract:

Software Defined Networking (SDN) has quickly developed as a technology to manage large-scale rapidly changing network environments at line-speed. This switch to centrally managed network devices potentially brings increased risks to the network infrastructure. If SDN applications can be thought of as programming the network, then SDN controllers must provide a protected environment in the same way that traditional operating systems isolate and protect software. This paper discusses the security concerns of SDN; examines current approaches to incorporating application permissions in SDN controllers, such as security-mode ONOS; and identifies where further work is needed to provide this assurance for operational networks.
