The document discusses the security measures for GIS data using the Geomajas framework, highlighting the importance of secure authentication methods such as certificates, biometrics, and tokens. It emphasizes the architecture that ensures no credential leakage and supports fine-grained policies while allowing for single sign-on capabilities. The conclusion is that Geomajas facilitates the construction of a highly secure GIS system with robust access controls.
