How to Defend against Sophisticated Intrusions in Home Networks Using SDN and NFV

Software-defined Home Networks (SDHN) is a key development trend of smart home. Security is still an important issue in SDHN. In this paper, a multi-stage attack mitigation mechanism is proposed for SDHN using Software-Defined Networking (SDN) and Network Function Virtualization (NFV). Firstly, an evidence-driven security assessment method using SDN factors and NFV-based detection is designed to perform security assessment along with observed security events. Secondly, an attack mitigation countermeasure selection method is proposed. The evaluation shows that the proposed mechanism is effective for multi-stage attack mitigation in SDHN.
