A Novel OA System Access Control Method Based on Improved RBAC Model

Access control is an indispensable part of the OA system. Reasonable access control can fundamentally guarantee data security. With the expansion of enterprise business scale and the adjustment of organizational structure, there will be more and more system users. Due to the sensitivity and privacy of business data, it is necessary to manage the authority of users in this system. In order to solve the problem of large granularity of permission management and strong coupling between access control code and business code, this paper compares the implementation scheme of existing access control system, realizes a fine-grained access control method based on improved RBAC model and achieves good results in practical system application.
