The Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN) is the most prestigious international forum for presenting research results in the field of dependability and security. The rapidly expanding Information Technologies (IT) increasingly form the basis of all imaginable and novel emergent application paradigms, with the technical aspects being as important as the growing socio-economical and societal values. Dependability and security aspects are essential, as both the society and individuals rely more and more on the services delivered by IT. Coping with attacks and unintentional faults in a rapidly evolving technological and application environment generates new challenges for the dependability and security community thus driving DSN. DSN is now in its fifth decade of evolution and has a sustained tradition to address both conceptual and applied research results related to actual questions posed by the rapid IT evolution. This flagship dependability conference addresses the entire spectrum of scientific and technological challenges which are indispensable to solve for partaking the benefits of modern IT. DSN 2013 aims at offering a value focused program including plenary talks, regular papers, experience reports, panels, student forum, fast abstracts, demonstrations of tools and technologies, debate sessions, together with state-of-the-art workshops and tutorials. The tradition of offering a high quality program assumes the contribution of the leading researchers and we look forward to your participation!
