This book constitutes the refereed proceedings of the 25th International Conference on Computer Safety, Reliability, and Security, SAFECOMP 2006. The 32 revised full papers were carefully reviewed and selected from 101 submissions. Topical sections include systems of systems, security and survivability analysis, nuclear safety and application of standards, formal approaches, networks dependability, coping with change and mobility, safety analysis and assessment, 6th FP integrated project DECOS, and modelling.

Cyberspace security is a critical subject of our times.

On one hand the development of Internet, mobile communications, distributed computing, computer software and databases storing essential enterprise information has helped to conduct business and personal communication between individual people. On the other hand it has created many opportunities for abuse, fraud and expensive damage. This book is a selection of the best papers presented at the NATO Advanced Research Workshop dealing with the Subject of Cyberspace Security and Defense. The level of the individual contributions in the volume is advanced and suitable for senior and graduate students, researchers and technologists who wish to get some feeling of the state of the art in several sub-disciplines of Cyberspace security.

Several papers provide a broad-brush description of national security issues and brief summaries of technology states. These papers can be read and appreciated by technically enlightened managers and executives who want to understand security issues and approaches to technical solutions. An important question of our times is not "Should we do something for enhancing our digital assets security," the question is "How to do it."

The safe operation of computer systems continues to be a key issue in many applications where people, environment, investment, or goodwill can be at risk. Such applications include medical, railways, power generation and distribution, road transportation, aerospace, process industries, mining, military and many others. This book represents the proceedings of the 12th International Conference on Computer Safety, Reliability and Security, held in Poznan, Poland, 27-29 October 1993. The conference reviews the state of the art, experiences and new trends in the areas of computer safety, reliability and security. It forms a platform for technology transfer between academia, industry and research institutions. In an expanding world-wide market for safe, secure and reliable computer systems SAFECOMP'93 provides an opportunity for technical developers, users, and legislators to exchange and review the experience, to consider the best technologies now available and to identify the skills and technologies required for the future. The papers were carefully selected by the International Program Com mittee of the Conference. The authors of the papers come from 16 different countries. The subjects covered include formal methods and models, safety assessment and analysis, verification and validation, testing, reliability issues and dependable software tech nology, computer languages for safety related systems, reactive systems technology, security and safety related applications. As to its wide international coverage, unique way of combining partici pants from academia, research and industry and topical coverage, SAFECOMP is outstanding among the other related events in the field."
