Submission deadline: May 06, 2011. The submission server is ready to welcome your submissions >> http://stdev.ifs.tuwien.ac.at/ares2011/<<Accepted papers will be published in the ARES proceedings. Selected best papers will be recommended for publication in the special issue “Security and Privacy in Business Networking” of the international journal “Electronic Markets” published by Springer.DescriptionPopulations of cities will continue to increase: the share of the world’s population living in cities is predicted to rise from 50% in 2011 to 70% in 2050. Threats to cities and their social infrastructures, e.g. from natural disasters, crime, and terrorism, endanger human life directly and indirectly. Resilience is gaining importance as a core concept to cope with such threats. In general, resilience means strengthening social infrastructures to prevent or mitigate such threats and to consistently deliver the intended services in a trustworthy and “normal” way even in changing situations. Information and communication infrastructure (IT) is one primary part of the social infrastructure and therefore one of the central objects of resilience research. The provision and processing of real-time information for communication, coordination, and cooperation is a vital role and IT still has to provide its services, e.g., to rescue organizations and for catastrophe management, when a threat becomes reality. Since resilience research is still in its infancy, the main objective of the RISI 2011 workshop is to identify research problems and to discuss future research initiatives regarding IT support for "Resilience in Social Infrastructures". We encourage academic researchers and industry experts to present and discuss novel ideas as well as ongoing work. Contributions addressing promising approaches, methods and tools supporting resistance against attacks and threats (i.e., prevent and protect) as well as to adapt social infrastructures to deal with threats and attacks (i.e., respond and recover) are invited.TopicsIdentification of vulnerabilities in service-oriented computing Critical Information Infrastructure Protection Modeling of resilience properties Data provenance Privacy-enhancing technologies Usage control mechanisms Resilience in cryptographic and communications protocols Digital forensics Measurements for Resilience Risk assessment and evaluation of IT risks Business Continuity Plan and Business Continuity Management Economics of controls Important Dates2011-05-06: Submission Deadline (extended!) 2011-05-13: Author Notification 2011-06-01: Author Registration Proceedings Version 2011-08-22 - 2011-08-26: Conference/WorkshopSubmission GuidelinesThe submission guidelines valid for the workshop are the same as for the ARES conference.
