Using Microsoft Office InfoPath to Generate XACML Policies

Today, when organizations perform access control over their resources they are not only interested in the user's identity, but in other data such as user's attributes or contextual information. These requirements can be found, for example, in a network access control scenario where end users pay for a specific access level and depending oil it. they call get different network quality of service. The network provider has to check. not only the user identity, but the user's attributes to make sure that he can access to the specified resource. These systems are based on the use of policy languages to define the authorization process. However, due to the increasing complexity of current systems. policies are becoming more and more complex to be managed by system administrators. Therefore, ill this paper we present an user friendly approach to policy specification, based on the use of high level templates and common desktop applications. These templates are easily built from XML schemas. and once they have been filled, a XACML policy is automatically generated using a XML transformation.
