Individualization is an enhancement of existing role concepts by subjective information demand. Role concepts, which belong to personalization, grant access to IT resources. This paper prepares the ground for a context-based approach that provides individual - as opposed to personalized - access to IT resources in heteroge-neous system landscapes. A central part of such an approach is the definition of user context. Here, we provide such a definition, derived from the state of the art in this field, along with a UML class model. Our definition of user context is validated by relating the UML context model to the authorization concepts of SAP R/3, AIX and Solaris.
