LAN network configuration

In this section, we propose role interaction based access control (RiBAC) models for the SCC model. Note that agent interaction is a key issue in a CC model. Furthermore, interactions authorized for agents are basically defined by what roles within the community the interacting agents are playing. Such interactions can hence be cast as accesses authorized for agents playing specific roles. For fine-grained rolebased policy specification, we categorize agent interactions within a community into two types, as depicted

Role-action interaction, shown in Fig.2.a, involves an initiator role (ri) interacting with a target role (rt) to indicate that the target role should perform some action it is capable of - in other words, we model this as the initiator role authorized to invoke the target role's LAN network configuration. The pair role and its action invocable by other roles can be considered as a role-action permission
