Research on SDN Security Technology of Satellite Ground Application System

Abstract

Software development in the network has made it has been more widely used in the meteorological satellite ground application system; SDN architecture is also facing more security issues. How to achieve SDN network security has become an urgent need to solve a problem. This paper proposed a SDN security method based on the correlation coefficient method. Firstly, SDN security is vectorized, and then the correlation between the security vector and the normal security vector is compared, and the security of the network is determined according to the correlation. The simulation results show that the method proposed in this paper can detect the non - security attack behavior accurately and has a high degree of discrimination.
