Defending Cyberspace with Software-Defined Networks

ABSTRACT

Software-Defined networking (SDN) presents a new way of thinking about and operating communication networks that is revolutionizing the networking industry. This paper first describes how a core tenet of SDN—a logically centralized network control plane—enables dynamic, fast, and predictable changes in network behavior. Next, the authors show how network operators can use this capability to transform defensive cyber operations from today’s labor-intensive, static processes into automated, agile responses that are capable of dealing with tomorrow’s cyber threats.
