Assembling and Administering Your Server
Managing Server Security
In addition to setting Windows permissions and using the access control
tools provided with your web server to control access to individual maps
(MWF files) at your site, you can add another level of security by using
Autodesk MapGuide Server to control access to the
resources
(SDF files, raster
image files, SQL data tables, and Zoom Goto Address definitions) used by
these published maps. This means that you can set up Autodesk MapGuide
Server to require additional authorization before providing resources
requested by a map, even if a user has access to the map. You can do this in
two ways:
Use access keys to provide time-sensitive, map-embedded, passive, trans-
action-based security.
Use user-group/password security to provide map-independent, active,
session-based security.
Access Keys Versus User IDs and Passwords
Access keys are passwords that the author of a map embeds in the definition
of the map layer. Each time the map layer requests map data, Autodesk
MapGuide Server verifies the embedded access key against the list of valid
access keys for the resource before fulfilling the request. Because this process
takes place automatically and invisibly every time the map layer requests
data, access keys are a convenient way to provide greater resource security
with no impact on the user. Additionally, access keys can be preset to be valid
for only a certain period of time, adding an additional level of control.
User passwords require the user to enter a valid user name and password at
the first request of map data from Autodesk MapGuide Server. Just like the
typical web server security model, the user name and password are required
only once for each layer that uses the restricted resource, providing a high
level of security without unnecessary impact on the user.
Together, access keys and user passwords provide a great deal of
flexibility in solving security problems over a variety of Internet/intranet
implementations.
