Abstract
The scale of the Software-Defined Network (SDN)
Controller design problem has become apparent with the expansion
of SDN deployments. Initial SDN deployments were
small-scale, single controller environments for research and usecase
testing. Today, enterprise deployments requiring multiple
controllers are gathering momentum e.g. Google’s backbone
network, Microsoft’s public cloud, and NTT’s edge gateway.
Third-party applications are also becoming available e.g. HP SDN
App Store. The increase in components and interfaces for the
evolved SDN implementation increases the security challenges of
the SDN controller design. In this work, the requirements of a
secure, robust, and resilient SDN controller are identified, stateof-the-art
open-source SDN controllers are analyzed with respect
to the security of their design, and recommendations for security
improvements are provided. This contribution highlights the gap
between the potential security solutions for SDN controllers and
the actual security level of current controller designs.
