Abstract : This report investigates technical security in open systems. Security in open systems is a special problem since each element in an open system (hardware, networks, operating systems and applications) must be able to offer security in coordination with other elements. Concepts found in preceding studies are further developed and new concepts are introduced. The concepts of current international standards are generalised such that they are applicable to open systems. Furthermore, the different concepts are confronted with one another and unified using new models. This study offers models and building blocks to create secure open elements that together will make up a secure open system. The study shows that it is possible to offer security services in open systems that are able to fulfil the majority of today's and tomorrow's requirements for security. The study also shows that there still is a long way to go: standardised interfaces, protocols and data structures must still be defined. However, none of this is beyond the state-of-the-art. Furthermore, the study shows that there is a viable evolutionary path from today's practices and standards towards tomorrow's secure open systems.
