概要 As the continuation of the previous manuscript, an application of Formal Concept Analysis for Information Flow Control between file servers is presented. A File Server Group is a system of plurality o...f file servers organized for controlling secure information flow among them. The configuration of files servers is derived from an organizational security policy by using formal concept analysis. Role-Based Access Control also can be implemented with a File Server Group. The File Server Group implements the Mandatory Access Control among sensitive files and users in an organization without introducing any "exotic" MAC tools such as secure OSs, security labels and global reference monitors. Those are virtually embedded into the configuration of the File Server Group. Adopting lattice structure and FCA, the configuration cost of File Server Group is lower than that of flat structured file server systems.続きを見る
