A Heterogeneity Evaluation for the of Mimic Network Control of SDN

Abstract:
By introducing the idea of dynamic heterogeneous redundancy, the problems of single control points of failure, unknown backdoor vulnerabilities, and static configuration can be effectively solved for SDN (Software-Defined Networking). Heterogeneity is an important indicator for evaluating the security of the system. This paper proposes two methods for measuring heterogeneity based on the biological population diversity assessment method. Heterogeneity quantification method based on system complexity and difference is proposed and another heterogeneous quantification method is established for the mimic system using high order symbiosis of vulnerabilities. The experimental results show that, compared to the known method, the heterogeneous quantification method 1 considers more comprehensive factors and is closer to reality. The heterogeneity quantification method 2 is more instructive to quantify the security of the system.
