Representation of Security and Dependability Solutions

Abstract

AmI considerations lead us to argue that it is essential for Security and Dependability (S&D) mechanisms to be able to adapt themselves to renewable context conditions in order to be applied to the ever-changing AmI scenarios. The key for this dynamic adaptation relies on the ability to capture the expertise of S&D engineers in such a way that it can be selected, adapted, used and monitored at runtime by automated means. S&D Artefacts proposed in this chapter represent the core of author's approach to precisely model such expertise in form of semantic descriptions. They adopt an integral methodology covering the complete system life cycle going from S&D Classes, mostly used at development time, to S&D Patterns and S&D Implementations, perfectly suited for deployment and runtime use. This chapter traces the foundations and internals of S&D Artefacts, describing how they are defined and structured, and how they are categorized and grouped to form an exhaustive library of sound S&D Solutions. © Springer Science + Business Media, LLC 2009.
