Current processes for providing security and dependability (S&D) in computing systems require a detailed a priori knowledge about the target systems and their environments. However, in many emergent computing scenarios like ubiquitous computing or ambient intelligence, it is not possible to foresee all possible situations that may arise at runtime so the necessary knowledge is not available at development time. In this paper we present the concept of S&D Pattern and the artefacts that we use to implement it, as the basis for the automated provision of S&D Solutions to running applications in highly dynamic and heterogeneous environments.
