Research on Network Security Situation Assessment Technology Based on Fuzzy Evaluation Method

With the development of Internet technology and the continuous improvement of social informatization, the network has gradually become an indispensable part of people's production and life. The importance of network security has received more and more attention. A variety of security products have been applied to the network to strengthen and maintain the safe operation of the network. However, these security means can only play a specific role in a certain range, and lack of effective data fusion and collaborative management mechanism. In the face of many scattered information, network security managers cannot respond to security incidents in time. For the purpose of grasping the current situation and changes of network security, network security situation awareness technology came into being, it has become a new hotspot in network security research. This paper proposes a fuzzy comprehensive evaluation model which combines AHP and fuzzy evaluation method to evaluate network security situation.
