Abstract An integrated user access control method was proposed to address the issues of security and management in networked manufacturing systems (NMS). Based on the analysis of the security issues in networked manufacturing system, an integrated user access control method composed of role-based access control (RBAC), task-based access control (TBAC), relationship-driven access control (RDAC) and coalition-based access control (CBAC) was proposed, including the hierarchical user relationship model, the reference model and the process model. The elements and their relationships were defined, and the expressions of constraints authorization were given. The extensible access control markup language (XACML) was used to implement this method. This method was used in the networked manufacturing system in the Shaoxing spinning region of China. The results show that the integrated user access control method can reduce the costs of system security maintenance and management.
