| Popis: | Role mining and setup affect the usage of role-based access control (RBAC). Traditionally, user’s role and permission assigning are manipulated by security administrator of system. However, the cost is expensive and the operating process is complex. A new role analyzing method was proposed by generating mappings and using them to provide recommendation for systems. The relation among sets of permissions, roles and users was explored by generating mappings, and the relation between sets of users and attributes was analyzed by means of the concept lattice model, generating a critical mapping between the attribute and permission sets, and making the meaning of the role natural and operational. Thus, a role is determined by permission set and user’s attributes. The generated mappings were used to automatically assign permissions and roles to new users. Experimental results show that the proposed algorithm is effective and efficient. |
