SDN in LANs: Programming the Network to Secure IoT Traffic

Context: both SDN and high-end IoT gaining maturity

In today’s world, we are surrounded by more and more connected devices, collecting data and offering services to ease every aspect of our connected lives. Whether it is for work, leisure, health, etc., we will increasingly interact with smart devices that we either own, or that are made accessible to us by third parties as different as friends or smart city providers. However, recent studies have shown that end users are concerned about the privacy and security issues this future is introducing [Trustee2015]. Hurdles include:

security, as some of these devices may not be powerful enough to handle strong security processes and as such can become an attack vector towards other devices;
data privacy, as we often don’t know when and how our personal data is collected, and by whom and for what purpose.
