Part of the DUD-Fachbeiträge book series (DUD)


SQUALE stands for „Security, Safety and Quality Evaluation for Dependable Systems“ and the goal of SQUALE project is to develop a scheme for the assessment of systems with a wide range of dependability requirements, using a common dependability framework, and combining techniques from current and emerging standards. We present the ideas of the project in order to promote discussion of the issues, and provide publicity for the new concepts which have been developed. To illustrate the application of the concepts an example is given which consists of the examination of a part of a railway signalling installation.
