CRAC: Confidentiality Risk Assessment and IT-Architecture Comparison

CRAC is an IT-architecture-based method for assessing and comparing confidentiality risks of distributed IT systems. The method determines confidentiality risks by taking into account the effects of the leakage of confidential information (e.g. industrial secrets), and the paths that may be followed by different attackers (e.g. insider and outsider). We evaluate its effectiveness by applying it to a real-world outsourcing case

IT Confidentiality Risk Assessment for an Architecture-Based Approach

Information systems require awareness of risks and a good understanding of vulnerabilities and their exploitations. In this paper, we propose a novel approach for the systematic assessment and analysis of confidentiality risks caused by disclosure of operational and functional information. The approach is based on a model integrating information assets and the IT infrastructure that they rely on for distributed systems. IT infrastructures enable one to analyse risk propagation possibilities and calculate the impact of confidentiality incidents. Furthermore, our approach is a mean to bridge the technical and businessoriented views of information systems, since the importance of information assets, which is leading the technical decisions, is set by the business
