A UML profile for requirements analysis of dependable software

Abstract

At Safecomp 2009, we presented a foundation for requirements analysis of dependable software. We defined a set of patterns for expressing and analyzing dependability requirements, such as confidentiality, integrity, availability, and reliability. The patterns take into account random faults as well as certain attacks and therefore support a combined safety and security engineering. In this paper, we demonstrate how the application of our patterns can be tool supported. We present a UML profile allowing us to express the different dependability requirements using UML diagrams. Integrity conditions are expressed using OCL. We provide tool support based on the Eclipse development environment, extended with an EMF-based UML tool, e.g., Papyrus UML. We illustrate how to use the profile to model dependability requirements of a cooperative adaptive cruise control system. © 2010 Springer-Verlag Berlin Heidelberg.
