Abstract:

With the development and popularization of Software-Defined Networking (SDN), security threats on SDN are on the rise. As one of the most common attacks on the Internet, Denial of Service (DoS) may possibly prevent SDN controllers from offering services through the consumption of network or system resources. This paper introduces Extenics into the research on strategy generation for the mitigation of DoS attacks against SDN controllers from the formal point of view. Considering the problem of generating the extension strategy for mitigation of DoS attacks against SDN controllers for SDN controllers, the extension strategy generation method based on Extenics is utilized. According to the performance indicators of SDN controllers, the generated mitigation strategy focuses on the dynamic adjustment of computing resources in order to reduce the negative effects of DoS attacks. The experimental analysis validates that the application of the extension strategy generation method is feasible and promotes the formalization to generate the strategy for mitigation of DoS attacks against SDN controllers.
