A key feature for the information systems is data security, but the Geoinformation Systems and Spatial Databases as well as their applications appear to have some drawbacks concerning that matter. Most suggestions about geodata confidentiality are obviously stuck in their attempts to link access rules with geometric properties of spatial data. In this paper we suggest a different approach toward build data access model and a complete data security system for a WinMAP system which includes account control, data access control based on an extended DAC and audit features. A data model of WinMAP is also described because its specialized features allow to rationally develop and effectively implement the data security system. An implementation of the extended DAC model is briefly sketched.
