Specifying Security for Layers Online Help Index layers security You can secure the data on a layer and control access to resources by setting an access key. The access key you specify is embedded in the layer, so that when Autodesk Mapguide Author or Autodesk MapGuide Viewer requests data from a resource for the layer, Autodesk MapGuide Server checks the resource access key against the layer access key. If the keys match, the Autodesk MapGuide Server loads the layer's data. If keys do not match, access to the resource data is denied. If the resource does not use an access key, the access key embedded in the layer is ignored. You can also control whether Autodesk MapGuide Viewer API users can obtain coordinate information from map features in your map and whether they can access the map layer setup. Disabling API access to the coordinates prevents developers from writing scripts that can download all of the coordinates on the layer and re-use the data.  You use the Security tab of the Map Layer Properties dialog box to specify security settings. For step-by-step instructions, choose Help Contents, click the Index tab, and look up "layers, security." Click the Help button for details about each option in the dialog box. 164 | Chapter 9 Working with Map Layers
