| Summary: | Migrating traditional access control,such as mandatory and discretionary access control,into role-based access control(RBAC)lightens a practical way to improve the user-permission management efficiency.To guarantee the security of RBAC system,it is important to generate proper roles during the migration.However,abnormal user-permission configurations lead to wrong roles and cause tremendous security risks.To hunt the potential abnormal user-permission configurations,a novel spectral clustering based abnormal configuration hunting framework was proposed and recommendations were given to correct these configurations.Experimental results show its performance over existing solutions. |
