In this paper we compare two approaches for implementing Security and Privacy systems in Cyberspace: a structured approach, such as done in Mokum, where access is governed by structure (of the classes), and two principles: the epistemic and the ontologic principle. The second approach is based on the use of capabilities, such as provided by ERP systems.
