Access control method of network security authentication information based on fuzzy reasoning algorithm

Abstract

In order to improve the network security and get the real-time situation of network security, the access control method of network security authentication information based on fuzzy reasoning algorithm is proposed. Firstly, a scheme of multi-data source analysis and situational perception assessment is proposed based on the factors of network physical security and service security. At the same time, on the basis of multi-source data fusion, fuzzy reasoning algorithm is used to mine and identify the network attack relevance, so as to achieve the perception control of network security situation. Then based on security situation mining control, role classification is introduced to realize network access control. Finally, the access control flow is designed by combining the physical structure, logical structure and use case diagram of access control. The multi-level security concept and role inheritance are used to control access, and the administrator role is used to restrict some users’ operation of transferring access rights. The experimental results show that the method has good security situation perception effect, excellent performance and reliability of network access control.
