Managing the lifecycle of XACML delegation policies in federated environments

Abstract This paper presents an infrastructure that enables the use of administrative delegation in an effective way, reducing the complexity in the policy management for some specific scenarios. This infrastructure is in charge of managing the policies of the system during its lifecycle, for example when they are created by the users or when they are collected to take an authorization decision. The proposal makes use of a robust and extensible language as XACML in order to express the authorization policies. However, as we will see, the management infrastructure has been designed in a way that facilitates the task of the different users involved, assuming that those users do not have to be security experts or XACML-aware. 1 Introduction an
