eTelligent Rules

You can use eTelligent Rules to define variables that enable fine-grained access-control criteria known as policy expressions.

Policy expressions are implemented as policy attributes. They include operators and customer-defined variables that are evaluated at runtime, when a user actually needs to access a protected resource on a Web site.

Variables can store local information that is within the enterprise or remote information that is provided by various Web Services.

The variables provided by eTelligent Rules are available in the Administrative UI. You can define variable objects and incorporate them into policy logic through policy expressions. You can also include variables in SiteMinder response objects.
