It is currently quite easy for students or designers/engineers to find very general books on the various aspects of safety, reliability and dependability of computer system architectures, and partial treatments of the elements that comprise an effective system architecture. It is not so easy to find a single source reference for all these aspects of system design. However, the purpose of this book is to present, in a single volume, a full description of all the constraints (including legal contexts around performance, reliability norms, etc.) and examples of architectures from various fields of application, including: railways, aeronautics, space, automobile and industrial automation. The content of the book is drawn from the experience of numerous people who are deeply immersed in the design and delivery (from conception to test and validation), safety (analysis of safety: FMEA, HA, etc.) and evaluation of critical systems. The involvement of real world industrial applications is handled in such as a way as to avoid problems of confidentiality, and thus allows for the inclusion of new, useful information (photos, architecture plans/schematics, real examples).
This book describes the design of a low complexity, fault-detecting computer architecture for utilisation in programmable logic controllers (PLCs) for process control purposes. The cyclic operating mode of PLCs and a specification level graphical programming paradigm based on interconnecting application-oriented standard software function modules are architecturally supported. Thus, by design, there is no semantic gap between the specification, programming and machine execution levels enabling the safety licensing of application software by diverse back translation, an extremely simple but rigorous method.

This volume provides a comprehensive overview of the many aspects and developments of safety-related applications of industrial computer systems. The book contains 21 papers covering such topics as the specification and design of safety systems, their testing and licensing, safety related documentation and management technqiues and their uses and limitations in industry, with examples in such diverse areas as nuclear power plants, the chemical industry and applications in traffic control.
Theimportanceofsafetyandsecurityisgrowingsteadily.Safetyisaqualityc- racteristic that traditionally has been considered to be important in embedded systems, and security is usually an essential property in business applications. There is certainly a tendency to use software-based solutions in safety-critical applications domains, which increases the importance of safety engineering te- niques. These include modelling and analysis techniques as well as appropriate processes and tools. And it is surely correct that the amount of con?dential data that require protection from unauthorized access is growing. Therefore, security is very important. On the one hand, the traditional motivations for addressing safety and security still exist, and their relevance has improved. On the other hand, safety and security requirements occur increasingly in the same system. At present, many software-based systems interact with technical equipment and they communicate, e.g., with users and other systems. Future systems will more and more interact with many other entities (technical systems, people, the en- ronment). In this situation, security problems may cause safety-related failures. It is thus necessary to address safety and security. It is furthermore required to take into account the interactions between these two properties.
This book constitutes the refereed proceedings of the 30th International Conference on Computer Safety, Reliability, and Security, SAFECOMP 2011, held in Naples, Italy, in September 2011. The 34 full papers presented together were carefully reviewed and selected from 100 submissions. The papers are organized in topical sections on RAM evaluation, complex systems dependability, formal verification, risk and hazard analysis, cybersecurity and optimization methods.
