摘要：In the 21st century, the network of teaching management not only improves its quality and efficiency but also brings convenience to teachers and students. However, as a network application system, it also faces a variety of security issues. In order to improve the system security, the widely-used RBAC control method is introduced in this paper. Based on the refinement of system privilege and user role, this paper puts forward the security management model of “user classification, role authorization, Unified management ”, which is more suited to the structure of multi-level applications by controlling the data range accessible to users, and ultimately achieves the purpose of strengthening the security of the system.
