Security and Privacy Challenges in Open and Dynamic Environments
June 1, 2006
Information system security and privacy, once narrow topics primarily of interest to IS designers, have become critically important to society at large. The scope of associated challenges and applications is broadening accordingly, leading to new requirements and approaches. Challenges arise as information systems evolve into distributed systems that are open in that they don’t pre-identify a set of known participants, and dynamic in that the participants change regularly, not just due to occasional failures. Such systems include peer-to-peer networks, grid computing environments, ad hoc networks, Web services, pervasive computing spaces, and multiagent systems. In addition, as applications become more sophisticated and intelligent, they require greater degrees of decision-making and independence. The long-range vision is of systems that let people, agents, services, and devices seamlessly interact as autonomously as possible while preserving appropriate security and privacy
