The Fourth International Conference on Availability, Reliability and Security ("ARES 2009 - The International Dependability Conference") will bring together researchers and practitioners in the area of dependability. ARES 2009 will highlight the various aspects of dependability - with special focus on the crucial linkage between availability, reliability and security.

ARES aims at a full and detailed discussion of the research issues of dependability as an integrative concept that covers amongst others availability, safety, confidentiality, integrity, maintainability and security in the different fields of applications.

The event will emphasize the interplay between foundations and practical issues of dependability in emerging areas such as e-government, m-government, location-based applications, ubiquitous computing, autonomous computing, chances of grid computing etc.

ARES is devoted to the critical examination and research challenges of the various aspects of Dependable Computing and the definition of a future road map.
