Abstract

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. Information networks are evolving into more open and dynamic systems. Security and privacy enforcement is problematic in these systems due to the lack of a common understanding of requirements and information as well as user unpredictability. Shared ontologies, declarative policies, and trust models offer the most promising approaches to meet these challenges.
