BSCM: Proposed security collaboration model based on blackboard

Abstract

Abstract. Security collaboration is necessary to improve integral security of network. But there is no unified model to ensure interoperability and collaboration within IDS, firewall and other network security components. We propose a security collaboration model by exploiting blackboard technique, named BSCM. In this model, network security components don't communicate with each other directly, but via a common blackboard which serves as the platform of information-sharing and events-responding. We introduce the " Registerfeedback" mechanism which connects the blackboard and all the components in BSCM. The formal definition of BSCM and a sample system are given in this paper. © Springer-Verlag 2004.
