Can the VDS provide context-based security?
Yes! The real value of a virtual directory resides in its capability to federate distributed, heterogeneous data sources. As a virtual directory, VDS can map objects, attributes and transform values. But VDS can also map and navigate the relationships linking different objects. This is particularly important in the case of many databases and applications where many relationships exist between different entities. In particular, these relationships extend the definition of identities in consideration of specific business contexts. In fact, most of the time an identity representing an individual does not contain all possible attributes at all times. Managing such a “mega” identity would be very difficult (how many facets to record?). It is the participation of this individual in different activities, involving different resources (business contexts) that confer to him some specific attributes characterizing his role.
