Detection and mitigation of denial-of-service attacks against software-defined networking

Software-defined networking (SDN) is an emerging architecture in computer networking that was introduced to fulfill the demand of current Internet-based services and applications. New features introduced in the SDN architecture open the space for attackers to disrupt the SDN-based networks using new types of Denial-of-Service (DoS) attacks. In this study, first, we present a new DoS attack, namely the control channel DoS attack. Second, we present another new DoS attack to overwhelm the flow table of the SDN switches, namely the flow rule overwhelming attack. Finally, we propose novel strategies to detect and mitigate DoS attacks against the SDN architecture
