The future development of air traffic management (ATM), set by the ATM 2000+ Strategy, involves a structural revision of ATM processes, a new ATM concept and a system approach for the ATM network. This requires ATM services to go through significant structural, operational and cultural changes that will contribute towards the ATM 2000+ Strategy. Moreover,(More)
Designing secure and dependable IT systems requires a deep analysis of organizational as well as social aspects of the environment where the system will operate. Domain experts and analysts often face security and dependability (S&D) issues they have already encountered before. These concerns require the design of S&D patterns to facilitate designers when(More)
Cloud governance, and in particular data governance in the cloud, relies on different technical and organizational practices and procedures, such as policy enforcement, risk management, incident management and remediation. The concept of accountability encompasses such practices, and is essential for enhancing security and trustworthiness in the cloud.(More)
This paper concerns decision-making processes that rely on trust. In particular, it analyzes how different aspects of trust (e.g., trust, trustworthiness, trustworthy evidence) influence trust decisions, and acting on them eventually. It proposes a trust decision model that structures the analysis of contextualized trust problems. Rather than seeking a(More)
