This chapter reflects on the paradigm shift from traditional concepts of access control and policy enforcement toward de-centralised methods for establishing trust between loosely connected entities. By delegating parts of enforcement tasks to trusted elements dispersed in a system, the system can establish transitive trust relationships. This is the most advanced evolution of the organisational method of separation of duties within IT security. The technological basis for trust in systems - Trusted Computing platforms - is described on conceptual levels allowing comparison with other top-level security concepts and mapping to application domains. Important applications in modern information systems and networks are exhibited.}, doi = {10.4018/978-1-61520-682-7.ch002}, isbn = {9781615206827}, keywords = {IT Security; Trust; Enforcement; Trusted Computing;}, url = {http://www.igi-global.com/Bookstore/TitleDetails.aspx?TitleId=37255} }
