On behalf of the Organizing Committee, we extend you a warm welcome to the 53rd Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN 2023), organized by the University of Coimbra, Portugal. Over the years DSN has become a forum to present the best world research in the fusion between dependability and security research, understanding the need to simultaneously fight against accidental faults, intentional cyber-attacks, design errors, and unexpected operating conditions. We are looking forward to a conference filled with ideas from industry and academia.

DSN 2023 will be held in Porto, Portugal, June 27-30. Porto is a vibrant city in the north of Portugal, the home of many high-tech companies that ship software products worldwide. Porto is a fascinating destination that you should not miss! From Porto you can easily reach many other fantastic places in Portugal. By train, bus, or car one can get to Coimbra, Lisbon, and many small villages in the interior of the country, where the food, the people, and the landscape will surprise you and create memories for life.

Join us in Porto, Portugal, in June 2023.
