Initially thought of with a strong emphasis on accidental faults, it has paid more attention over the years to intentional ones and, thus, to classical security concepts as well. Recently, a couple of incidents have received a lot of attention: the Hydraq and Stuxnet worms outbreaks. They have been used to highlight what is being presented as a new and growing security concern, namely the so-called advanced persistent threats (a.k.a. apts). In this paper, the authors analyze how resilient the historical dependability framework can be with respect to these sudden changes in the threats landscape.
