The networked home with refrigerators and washing machines connected to the Internet and reachable through Web browsers will be reality soon. Following this development, the market for electronically deliverable services will evolve. Companies that want to provide electronic services cannot be expected to deal with cable, network and routing problems-they need to rely and build on a common, secure hard- and software infrastructure that allows services to reach the customers' homes. We call such an infrastructure an e-services system (e-SS). In this paper we present the infrastructure of an example e-SS, highlight a number of specific security issues and show how they can be addressed in the early stages of the design of an e-SS.
