The complexity of modern-day information systems creates large dependability challenges. As described in the ReSIST (Resilience for Survivability in IST) working programme [1], "current state-of-knowledge and state-of-the-art reasonably enable the construction and operation of critical systems, be they safety-critical (e.g., avionics, railway signalling, nuclear control) or availability-critical (e.g., back-end servers for transaction processing). However, the situation drastically worsens when considering large, networked, evolving, systems either fixed or mobile, with demanding requirements driven by their domain of application, i.e., ubiquitous systems. There is statistical evidence that these emerging systems suffer froma significant drop in dependability and security in comparison with the former systems. There is thus a  dependability and security gap opening in front of us that, if not filled, will endanger the very basis and advent of information systems."
