Dependable Computing for Critical Applications 4 -

. .

Résumé :
This book contains articles accepted for presentation at the 4th IFIP Working Conference on Dependable Computing for Critical Applications. 21 papers selected from a total of 95 submitted articles address all aspects of dependability, a broad term defined as the degree of trust that may justifiably be placed in a system's reliability, availability, safety, security and performance. The presentations aim to contribute to a unified understanding and integration of these concepts, so future computer based systems will indeed be more dependable. In addition contributions to three panel sessions are included: The first, entitled Formal Methods for Safety in Critical Systems explored the role of formal methods in specifying and assessing system safety; the second, entitled Qualitative versus Quantitative Assessment of Security? debated the role that methods based on mathematical logic and stochastic techniques ought to play in assessing system security; and the third entitled Common Techniques for Fault-tolerance and Security explored techniques that are useful for attaining both fault-tolerance and security.
