The main objective of the CORAS project is to provide methods and tools for precise, unambiguous, and efficient risk assessment of security critical systems. To this end, we advocate a model-based approach to risk assessment, and this paper attempts to define the required models for this. Whereas traditional risk assessment is performed without any formal(More)
The EU-funded CORAS project (IST-2000-25031) is developing a framework for model-based risk assessment of security-critical systems. This framework is characterised by: (1) A careful integration of techniques and features from partly complementary risk assessment methods. (2) Patterns and methodology for UML oriented modelling targeting the different risk(More)
