Using gray model for the evaluation index and forecast of network security situation

Network security situation is a hot research realm in the area of network security, which helps security analysts to solve the challenges they encounter. This paper presents the evaluation index, and the characteristic attributes to describe the state of network situation, discusses the grey model includes grey correlation model and grey forecast algorithm to get the evaluation index and predication of network situation. The network situation based on the grey model using evaluation index .is proposed and the experimental result is shown in this paper.
