GIS system and security

With the development of information technology, information security issues become more important and severe, and the widespread use of service-oriented GIS makes GIS service security more attractive. GIS applications change from the stand-alone to the network applications. And GIS functions are changing from the client to the server side, from two-dimensional GIS to 2D&3D integration of GIS. The security, three-dimensional service data security of Service GIS software has become increasingly important. How to protect the security of GIS server, protect the content of GIS services, ensure the normal operation of GIS service, is a must solving problem for service GIS .

A GIS server generally contains one or more spatial databases, which store massive amounts of geographic data. Once the data is compromised or destroyed, it results in very serious impact. Therefore, to ensure the reliability and security of GIS server data is particularly important. In addition, the existing service-oriented GIS has been able to meet the different users for different data, different service needs. In the face of this differentiated application requirements, service security should also be differentiated: different users have different access to GIS services, that is, the user access controlling to prevent unauthorized use of GIS services.

In addition, GIS systems are generally composed from the server to the client. The security is not to control one software security only. Considering the security of GIS system, we should also ensure that the various parts of GIS system share a unified and compatible security scheme from the global point of view. This is the main security strategy of the SuperMap GIS system.
