Book Description
Safety Aspects of Computer Control focuses on the increased usage of computers and safety procedures for the control of their applications. The selection first elaborates on software in safety-related systems, regulatory issues, and legal liability. Topics cover product liability, liability under the contract law, liability under the law of negligence, methods of ensuring safety, some aspects of regulation of software safety, purpose and principles of regulation, and direct regulation. The book then examines standardization efforts worldwide; real-time software requirements specification and animation using extended Petri nets; and independent software verification and validation in practice. Discussions focus on verification and validation principles, organizational principles, specification language, extended Petri nets environment, history of software standards, and standardization work realized through ISO or IEC. The manuscript takes a look at design and licensing of safety-related software, fault-tolerant control for safety, and use and relevance for the development of safety-critical systems. Concerns include formal methods in the safety-critical systems life cycle, random and systematic failures, hardware and systematic failures, and software quality standards. The book is highly recommended for computer science experts and researchers interested in the safety aspects of computer control.

Book Description
Safety of Computer Control Systems 1985 (Safecomp '85): Achieving Safe Real Time Computer Systems presents the proceedings of the Fourth IFAC Workshop, held in Como, Italy, on October 1–3, 1985. This book discusses a wide range of topics ranging from direct process control through robotics to operator assistance. Organized into 28 chapters, this compilation of papers begins with an overview of the implementation of atomic actions by means of concurrent programming constructs. This text then examines the safety-related applications that usually demand the provision of redundant resources within the system. Other chapters consider the safe performance of an industrial robot system that relies on several factors. This book discusses as well the increasing demand for Computer Assisted Decision Making (CADM) both in engineering and service industries. The final chapter deals with the ways of reducing the effects of an error introduced during the design of a program. This book is a valuable resource for software engineers.

Book Description
Safety of Computer Control Systems 1983: Achieving Safe Real Time Computer Systems contains the proceedings of the Third IFAC/IFIP Workshop held at Cambridge, UK on September 20-22, 1983. Composed of 36 chapters, separated into the eight sessions of the workshop, this book begins with a discussion of the safety and reliability of computer control systems. Subsequent chapters explore the systems design for safety and reliability; fault tolerance, recovery, and use of redundancy; and aspects of fault tolerance for system reliability. Other chapters detail specification techniques; system development and quality assurance; verifications and validations; case studies; as well as scheduling, networks, and communications.

Book Description
Computer Control and Human Error presents accounts of various incidents at computer-controlled plants. These incidents include equipment and software faults; treating the computer as a "black box"; misjudging the way operators respond to the computer; errors in the data entry; failure to inform operators of changes in data or programs; and unauthorized interference with peripheral equipment. The discussion then turns to the use of hazard and operability studies (Hazops) to prevent or reduce errors in computer-controlled plants. The book describes the conventional Hazop as used in the process industry and an overview of the different Chazop frameworks/guidelines suggested by engineers and researchers. It then presents new Chazop methodology which is based on incident analysis. The final chapter presents reasons for failures in computerized systems, each of which is illustrated with an example. Most of the examples did not cause an actual safety problem, simply because they occurred within systems that are not safety-related. Some of these examples appear in the literature; others are from personal experience or from private communications.

Book Description
The market for safe, secure and reliable computer systems is expanding continuously and these Proceedings provide an opportunity to review the growth during the last decade and identify skills and technologies required for continued development in the area. The papers cover the experiences gained from specifying, creating, operating, and licensing computers in safety, security and reliability related applications. There are reviews of guidelines and industrial applications, with a section covering methods and tools used in designing, documenting, analysing, testing and assessing systems dependent on the SAFECOMP factors.

Book Description
The proceedings of the fifth workshop in this subject continue the trend set by the previous four and discusses some of the current problems involved in the design and production of safe real-time computer systems. Topics covered include software quality assurance, software fault tolerance, design for safety, and reliability and safety assessment. Every paper details the theoretical and practical problems involved in the development of safe systems and should therefore be of interest to all those involved in systems design.

Book Description
Computers at Risk presents a comprehensive agenda for developing nationwide policies and practices for computer security. Specific recommendations are provided for industry and for government agencies engaged in computer security activities. The volume also outlines problems and opportunities in computer security research, recommends ways to improve the research infrastructure, and suggests topics for investigators. The book explores the diversity of the field, the need to engineer countermeasures based on speculation of what experts think computer attackers may do next, why the technology community has failed to respond to the need for enhanced security systems, how innovators could be encouraged to bring more options to the marketplace, and balancing the importance of security against the right of privacy.

Book Description
We are building systems today-and using computers to control them-that have the potential for large-scale destruction of life and environment. More than ever, software engineers and system developers, as well as their managers, must understand the issues and develop the skills needed to anticipate and prevent accidents. Nancy Leveson examines what is currently known about building safe electromechanical systems and looks at past accidents to see what practical lessons can be applied to new computer-controlled systems.
