As computer systems become increasingly large and complex, their Dependability, Security and Autonomy play critical role at supporting next-generation science, engineering, and commercial applications. These systems consist of heterogeneous software/hardware/network components of changing capacities, availability, and in varied contexts. They provide computing services to large pools of users and applications, and thus are exposed to a number of dangers such as accidental/deliberate faults, virus infections, malicious attacks, illegal intrusions, and natural disasters etc. As a result, too often computer systems fail, become compromised, or perform poorly and therefore untrustworthy. Thus, it remains a challenge to design, analyze, evaluate, and improve the dependability and security for a trusted computing environment. Trusted computing targets computing and communication systems as well as services that are autonomous, dependable, secure, privacy protect-able, predictable, traceable, controllable, assessable and sustainable. The scale and complexity of information systems evolve towards overwhelming the capability of system administrators, programmers, and designers. This calls for the autonomic computing paradigm, which meets the requirement of self-management by providing self-optimization, self-healing, self-configuration, and self-protection. As a promising means to implement dependable and secure systems in a self-managing manner, autonomic computing technology needs to be further explored. On the other hand, any autonomic system must be trustworthy to avoid the risk of losing control and retain confidence that the system will not fail. Trusted and autonomic computing and communications need synergistic research efforts covering many disciplines, ranging from computer science and engineering, to the natural sciences to the social sciences. It requires scientific and technological advances in a wide variety of fields, as well as new software, system architectures, and communication systems that support the effective and coherent integration of the constituent technologies. DASC2011 is the second conference event following DASC2009 (December 2009, Chengdu, China) after the merger of the successful DASC symposium series previously held as RAMPDS-05 (July 2005, Fukuoka, Japan), DASC-06 (September 2006, Indianapolis, USA), DASC-07 (September, 2007, Columbia, MD, USA), and the successful SecUbiq symposium series, previously held as SecUbiq-05 (December 2005, Nagasaki, Japan), SecUbiq-06 (August 2006, Seoul, Korea), SecUbiq-07 (December 2007, Taipei, Taiwan) and SecUbiq-08 (December 2008, Shanghai, Shanghai). DASC2011 is to bring together computer scientists, industrial engineers, and researchers to discuss and exchange experimental and theoretical results, novel designs, work-in-progress, experience, case studies, and trend-setting ideas in the areas of dependability, security, trust and/or autonomic computing systems. Sydney is the largest city of Australia. Sydney is a centre for commerce, education, industry, sports and tourism. Sweeping harbour views, attractive and interesting architecture combined with year round mild weather makes Sydney a great place to visit such as Sydney Opera House, Sydney Harbour Bridge and Blue Mountain. Various one-day trips and other types of trips can be enjoyed while atmosphere of Xmas in Sydney is coming to the stage.
