Software Defined Network (SDN) is a programmable network that separates the network data plane from the control plane. However, lots of security threats and issues are concerned in software defined network. In this work, in order to reasonably complete the cyber attack situation evaluation in the SDNs, we proposed a cyber attack situation evaluating method based on multi-dimensional features analysis in SDNs. Cyber attack detection features were considered and improved their computation methods about four typical cyber attacks in SDN. Correlations vectors between any two different cyber attack features using variety of measures was considered.

Mininet was used to establish our experiment environment, in which we simulated four typical cyber attacks to verify and analyze our method in the experiment.
