Dependable Requirements Engineering and Change Management of Security-Critical ICT-Driven Systems

Abstract

This paper brings into focus the influence of dependable requirements engineering and change management in the dependability of specially security-critical ICT-driven systems, and suggests efforts towards a unified framework for taking into account the correlations and conflicts between security and other system dependability factors (safety, reliability, accessibility, flexibility, user-friendliness, etc.) when engineering the ICT-driven systems and when introducing changes in the original requirements defined at different levels of the systems’ development process.
