Engineering Methods And Tools For Software Safety And Security

As a consequence of the wide distribution of software and software infrastructure, information security and safety depend on the quality and excellent understanding of its functioning. Only if this functionality is guaranteed as safe, customer and information are protected against adversarial attacks and malfunction. A vast proportion of information exchange is dominated by computer systems. Due to the fact that technical systems are more or less interfaced with software systems, most information exchange is closely related to software and computer systems.

Based on the specific needs in applications of software technology, models and formal methods must serve the needs and the quality of advanced software engineering methods. This book provides a presentation of topics on how to meet such challenges covering both theoretical foundations and industrial practice.

This first-of-its-kind resource offers a broad and detailed understanding of software systems engineering from both security and safety perspectives. Addressing the overarching issues related to safeguarding public data and intellectual property, the book defines such terms as systems engineering, software engineering, security, and safety as precisely as possible, making clear the many distinctions, commonalities, and interdependencies among various disciplines. You explore the various approaches to risk and the generation and analysis of appropriate metrics. This unique book explains how processes relevant to the creation and operation of software systems should be determined and improved, how projects should be managed, and how products can be assured. You learn the importance of integrating safety and security into the development life cycle. Additionally, this practical volume helps identify what motivators and deterrents can be put in place in order to implement the methods that have been recommended.

Recent decades have seen major advances in methods and tools for checking the safety and security of software systems. Automatic tools can now detect security flaws not only in programs of the order of a million lines of code, but also in high-level protocol descriptions. There has also been something of a breakthrough in the area of operating system verification. This book presents the lectures from the NATO Advanced Study Institute on Tools for Analysis and Verification of Software Safety and Security; a summer school held at Bayrischzell, Germany, in 2011. This Advanced Study Institute was divided into three integrated modules: Foundations of Safety and Security, Applications of Safety Analysis and Security Analysis. Subjects covered include mechanized game-based proofs of security protocols, formal security proofs, model checking, using and building an automatic program verifier and a hands-on introduction to interactive proofs. Bringing together many leading international experts in the field, this NATO Advanced Study Institute once more proved invaluable in facilitating the connections which will influence the quality of future research and the potential to transfer research into practice. This book will be of interest to all those whose work depends on the safety and security of software systems.

Software Security Engineering draws extensively on the systematic approach developed for the Build Security In (BSI) Web site. Sponsored by the Department of Homeland Security Software Assurance Program, the BSI site offers a host of tools, guidelines, rules, principles, and other resources to help project managers address security issues in every phase of the software development life cycle (SDLC). The book’s expert authors, themselves frequent contributors to the BSI site, represent two well-known resources in the security world: the CERT Program at the Software Engineering Institute (SEI) and Cigital, Inc., a consulting firm specializing in software security. This book will help you understand why Software security is about more than just eliminating vulnerabilities and conducting penetration tests Network security mechanisms and IT infrastructure security services do not sufficiently protect application software from security risks Software security initiatives should follow a risk-management approach to identify priorities and to define what is “good enough”–understanding that software security risks will change throughout the SDLC Project managers and software engineers need to learn to think like an attacker in order to address the range of functions that software should not do, and how software can better resist, tolerate, and recover when under attack

To make communication and computation secure against catastrophic failure and malicious interference, it is essential to build secure software systems and methods for their development. This book describes the ideas on how to meet these challenges in software engineering.

In the last few years we have all become daily users of Internet banking, social networks and cloud services. Preventing malfunctions in these services and protecting the integrity of private data from cyber attack are both current preoccupations of society at large. While modern technologies have dramatically improved the quality of software, the computer science community continues to address the problems of security by developing a theory of formal verification; a body of methodologies, algorithms and software tools for finding and eliminating bugs and security hazards. This book presents lectures delivered at the NATO Advanced Study Institute (ASI) School Marktoberdorf 2015 – ‘Verification and Synthesis of Correct and Secure Systems'. During this two-week summer school, held in Marktoberdorf, Germany, in August 2015, the lecturers provided a comprehensive view of the current state-of-the-art in a large variety of subjects, including: models and techniques for analyzing security protocols; parameterized verification; synthesis of reactive systems; software model checking; composition checking; programming by examples; verification of current software; two-player zero-sum games played on graphs; software security by information flow; equivalents – combinatorics; and analysis of synthesis with 'Big Code'. The Marktoberdorf ASIs have become a high-level scientific nucleus of the international scientific network on formal methods, and one of the major international computer science summer schools. This book will be of interest to all those seeking an overview of current theories and applications in formal verification and security.

Developing secure software requires the integration of numerous methods and tools into the development process, and software design is based on shared expert knowledge, claims, and opinions. Empirical methods, including data analytics, allow extracting knowledge and insights from the data that organizations collect from their processes and tools, and from the opinions of the experts who practice these processes and methods. This book introduces the reader to the fundamentals of empirical research methods, and demonstrates how these methods can be used to hone a secure software development lifecycle based on empirical data and published best practices.
