Design on Security Linkage Strategy of Power Information Network Terminal

This paper proposes a security linkage strategy algorithm to accomplish the performance evaluation of network safety, which effectively decreases the amount of computation and improves efficiency. Moreover, different security applications have their own requirements for safety, so that this paper thoroughly considers the security service types of various applications. The methods to compute network safety scores based on fuzzy logic are designed for four different kinds of services, fulfilling security applications’ requirements. In addition, this paper gives full considers the situation that current network conditions are not representative of future situations, but current network status changes usually show certain trends which can predict the future conditions, thus providing more comprehensive network information to security linkage strategy.
