Integrity and security in AM/FM-GIS

The authors present the integrity and security requirements of AM/FM-GIS (geographic information system) systems, involving the security of the operating system, the DBMS (database management systems), and graphic information. Well-established security services and mechanisms developed for EDP on-line systems can be applied to AM/FM-GIS. In AM/FM-GIS, the security issue can be approached with formal methods in the pre-evaluation and evaluation phases. The security requirements should produce a well-defined input to the system design and could influence the selection of the data base with regard to the implementation technique. In AM/FM-GIS systems, different access modes should be possible on several data structures: layers, element groups, objects, and drawings
