Towards provisioning of SDN/NFV-based security enablers for integrated protection of IoT systems

Nowadays the adoption of IoT solutions is gaining high momentum in several fields, including energy, home and environment monitoring, transportation, and manufacturing. However, cybersecurity attacks to low-cost end-user devices can severely undermine the expected deployment of IoT solutions in a broad range of scenarios. To face these challenges, emerging software-based networking features can introduce new security enablers, providing further scalability and flexibility required to cope with massive IoT. In this paper, we present a novel framework aiming to exploit SDN/NFV-based security features and devise new efficient integration with existing IoT security approaches. The potential benefits of the proposed framework is validated in two case studies. Finally, a feasibility study is presented, accounting for potential interactions with open-source SDN/NFV projects and relevant standardization activities.
