Can we rely on computers? The individual aspects of system dependability, reliability, availability, safety, and security are the factors that determine application success. To answer this question, the text explores the integration of these dependability attributes within practical working systems. This is an important new title in the series on Dependable Computing and Fault-Tolerant Systems.
The International Working Conference on Dependable Computing for Critical Applications was the first conference organized by IFIP Working Group 10. 4 "Dependable Computing and Fault Tolerance", in cooperation with the Technical Committee on Fault-Tolerant Computing of the IEEE Computer Society, and the Technical Committee 7 on Systems Reliability, Safety and Security of EWlCS. The rationale for the Working Conference is best expressed by the aims of WG 10. 4: " Increasingly, individuals and organizations are developing or procuring sophisticated computing systems on whose services they need to place great reliance. In differing circumstances, the focus will be on differing properties of such services - e. g. continuity, performance, real-time response, ability to avoid catastrophic failures, prevention of deliberate privacy intrusions. The notion of dependability, defined as that property of a computing system which allows reliance to be justifiably placed on the service it delivers, enables these various concerns to be subsumed within a single conceptual framework. Dependability thus includes as special cases such attributes as reliability, availability, safety, security. The Working Group is aimed at identifying and integrating approaches, methods and techniques for specifying, designing, building, assessing, validating, operating and maintaining computer systems which should exhibit some or all of these attributes. " The concept of WG 10. 4 was formulated during the IFIP Working Conference on Reliable Computing and Fault Tolerance on September 27-29, 1979 in London, England, held in conjunction with the Europ-IFIP 79 Conference.

This volume contains the papers presented. at the Third IFIP International Working Conference on Dependable Computing for Critical Applications, sponsored by IFIP Working Group 10.4 and held in Mondello (Sicily), Italy on September 14-16, 1992. System developers increasingly apply computers where they can affect the safety and security of people and equipment. The Third IFIP International Working Conference on Dependable Computing for Critical Applications, like its predecessors, addressed various aspects of computer system 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. Because the scope of the conference was so broad, we hope the presentations and discussions will contribute to the integration of these concepts so that future computer-based systems will indeed be more dependable. The Program Committee selected 18 papers for presentation from a total of 7 4 submissions at a May meeting in Newcastle upon Tyne, UK. The resulting program represented a broad spectrum of interests, with papers from universities, corporations, and government agencies in eight countries. Much diligent work by the Program Committee and the quality of reviews from more than a hundred external referees from around the world, for which we are most grateful, significantly eased the production of this technical program.
This volume contains the articles presented at the Fourth InternationallFIP Working Conference on Dependable Computing for Critical Applications held in San Diego, California, on January 4-6, 1994. In keeping with the previous three conferences held in August 1989 at Santa Barbara (USA), in February 1991 at Tucson (USA), and in September 1992 at Mondello (Italy), the conference was concerned with an important basic question: can we rely on computer systems for critical applications? This conference, like its predecessors, addressed various 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. Because of its broad scope, a main goal was to contribute to a unified understanding and integration of these concepts. The Program Committee selected 21 papers for presentation from a total of 95 submissions at a September meeting in Menlo Park, California. The resulting program represents a broad spectrum of interests, with papers from universities, corporations and government agencies in eight countries. The selection process was greatly facilitated by the diligent work of the program committee members, for which we are most grateful. As a Working Conference, the program was designed to promote the exchange of ideas by extensive discussions. All paper sessions ended with a 30 minute discussion period on the topics covered by the session. In addition, three panel sessions have been organizcd.
Dependable Computing Covering dependability from software and hardware perspectives Dependable Computing: Design and Assessment looks at both the software and hardware aspects of dependability. This book: Provides an in-depth examination of dependability/fault tolerance topics Describes dependability taxonomy, and briefly contrasts classical techniques with their modern counterparts or extensions Walks up the system stack from the hardware logic via operating systems up to software applications with respect to how they are hardened for dependability Describes the use of measurement-based analysis of computing systems Illustrates technology through real-life applications Discusses security attacks and unique dependability requirements for emerging applications, e.g., smart electric power grids and cloud computing Finally, using critical societal applications such as autonomous vehicles, large-scale clouds, and engineering solutions for healthcare, the book illustrates the emerging challenges faced in making artificial intelligence (AI) and its applications dependable and trustworthy. This book is suitable for those studying in the fields of computer engineering and computer science. Professionals who are working within the new reality to ensure dependable computing will find helpful information to support their efforts. With the support of practical case studies and use cases from both academia and real-world deployments, the book provides a journey of developments that include the impact of artificial intelligence and machine learning on this ever-growing field. This book offers a single compendium that spans the myriad areas in which dependability has been applied, providing theoretical concepts and applied knowledge with content that will excite a beginner, and rigor that will satisfy an expert. Accompanying the book is an online repository of problem sets and solutions, as well as slides for instructors, that span the chapters of the book.
This book constitutes the refereed proceedings of the First Latin-American Symposium on Dependable Computing, LADC 2003, held in Sao Paulo, Brazil in October 2003. The 21 revised full papers presented together with abstracts of invited talks, a panel, workshops, and tutorials were carefully reviewed and selected for presentation. The papers are organized in topical sections on fault injection, security, adaptive fault tolerance, distributed algorithms, and components and fault tolerance.
This volume contains the papers presented at the Second International Work ing Conference on Dependable Computing for Critical Applications, sponsored by IFIP Working Group lOA and held in Tucson, Arizona on February 18-20, 1991. In keeping with the first such conference on this topic, which took place at the University of California, Santa Barbara in 1989, this meeting was like wise concerned with an important basic question: Can we rely on Computers? In more precise terms, it addressed various aspects of computer system de pendability, a broad concept defined as th'e trustworthiness of computer service such that reliance can justifiably be placed on this service. Given that this term includes attributes such as reliability, availability, safety, and security, it is our hope that these papers will contribute to further integration of these ideas in the context of critical applications. The program consisted of 20 papers and three panel sessions. The papers were selected from a total of 61 submissions at a November 1990 meeting of the Program Committee in Ann Arbor, Michigan. We were very fortunate to have a broad spectrum of interests represented, with papers in the final program coming from seven different countries, representing work at universities, corporations, and government agencies. The process was greatly facilitated by the diligent work of the Program Committee and the quality of reviews provided by outside referees. In addition to the paper presentations, there were three panel sessions or ganized to examine particular topics in detail.
It was with great pleasure that, on behalf of the entire organizing committee, I welcomed participants to EDCC-4, the Fourth European Dependable Computing Conference, held for the ?rst time in France. The fourth issue of EDCC carried on the traditions established bythe previous conferences in this series: EDCC-1 was held in Berlin (Germany) in October 1994, EDCC-2 in Taormina (Italy) in October 1996, and EDCC-3 in Prague (Czech Republic) in September 1999. EDCC evolved from a merger of tow other conference series at the moment when the Iron Curtain fell. One of these, known as the ”International Conf- ence on Fault-Tolerant Computing Systems”, was organized during the period 1982–1991, bythe German Technical Interest Group ”Fault-Tolerant Computing Systems”. The other series, known as the ”International Conference on Fault- Tolerant Systems and Diagnostics”, was organized during the period 1975–1990 in the former Czechoslovakia, Poland, Bulgaria, and the former GDR. The c- position of the EDCC steering committee and the organizing committees of the successive issues of the conference have mirrored the East–West uni?cation ch- acter of the conference series. The EDCC conference is becoming a unique meeting point for researchers and practitioners from all over the world in the ?eld of Dependable Systems. It is organized bythe SEE Working Group ”Dependable Computing” in France, the GI/ITG/GMA Technical Committee on Dependabilityand Fault Tolerance in Germany, and the AICA Working Group ”Dependability of Computer Systems” in Italy. Furthermore, committees of several global professional organizations, such as IEEE and IFIP, support the conference.
