Security Aspects and Models in Cooperative Production Processes

Cooperative production is increasingly important in today’s globalized competitive economy, especially for small and medium-sized enterprises (SME). Companies work together and by this share their competencies, information and resources to optimize production. The flexibility demands towards the supporting software applications not only concern the processes and services, but also security aspects. In this paper we focus on access control. A range of security models is studied with respect to their suitability of fulfilling the security requirements for cooperative production. Included are established models such as role-based access control (RBAC), or noticeable ones like attribute-based access control (ABAC), but also rather little-known ones such as break-the-glass (BTG) or intend-based access control (IBAC). The requirements discussed are based on literature study and results of a current application-oriented research project. Finally a recommendation for some specific security models is argued.
