This book focuses on software architecture and the value of architecture in the development of long-lived, mission-critical, trustworthy software-systems. The author introduces and demonstrates the powerful strategy of “Managed Evolution,” along with the engineering best practice known as “Principle-based Architecting.” The book examines in detail architecture principles for e.g., Business Value, Changeability, Resilience, and Dependability. The author argues that the software development community has a strong responsibility to produce and operate useful, dependable, and trustworthy software. Software should at the same time provide business value and guarantee many quality-of-service properties, including security, safety, performance, and integrity. As Dr. Furrer states, “Producing dependable software is a balancing act between investing in the implementation of business functionality and investing in the quality-of-service properties of the software-systems.” The book presents extensive coverage of such concepts as: Principle-Based Architecting Managed Evolution Strategy The Future Principles for Business Value Legacy Software Modernization/Migration Architecture Principles for Changeability Architecture Principles for Resilience Architecture Principles for Dependability The text is supplemented with numerous figures, tables, examples and illustrative quotations. Future-Proof Software-Systems provides a set of good engineering practices, devised for integration into most software development processes dedicated to the creation of software-systems that incorporate Managed Evolution.
Cyber Security Engineering is the definitive modern reference and tutorial on the full range of capabilities associated with modern cyber security engineering. Pioneering software assurance experts Dr. Nancy R. Mead and Dr. Carol C. Woody bring together comprehensive best practices for building software systems that exhibit superior operational security, and for considering security throughout your full system development and acquisition lifecycles. Drawing on their pioneering work at the Software Engineering Institute (SEI) and Carnegie Mellon University, Mead and Woody introduce seven core principles of software assurance, and show how to apply them coherently and systematically. Using these principles, they help you prioritize the wide range of possible security actions available to you, and justify the required investments. Cyber Security Engineering guides you through risk analysis, planning to manage secure software development, building organizational models, identifying required and missing competencies, and defining and structuring metrics. Mead and Woody address important topics, including the use of standards, engineering security requirements for acquiring COTS software, applying DevOps, analyzing malware to anticipate future vulnerabilities, and planning ongoing improvements. This book will be valuable to wide audiences of practitioners and managers with responsibility for systems, software, or quality engineering, reliability, security, acquisition, or operations. Whatever your role, it can help you reduce operational problems, eliminate excessive patching, and deliver software that is more resilient and secure.
Trustworthy systems are essential for critical operations—they ensure that reliability, usability, interoperability, and security are built into the systems, and that the systems deliver when they are most needed. There are environments where trustworthiness is an essential property in military, government, and civil domains. Examples include missile deployment control systems, the tax submission system of the federal government, and nuclear safety control systems. However, not many methods exist for the systematic engineering of trustworthy software systems. In this chapter we describe the application of the NFR Approach for designing a trustworthy software system. The NFR Approach, where NFR stands for “non-functional requirement,” treats trustworthiness as a goal to be achieved during the process of software development. The NFR Approach uses a structure called the Softgoal Interdependency Graph to capture the trustworthiness definition, depict architectural elements as softgoals, and rationalize the extent of trustworthiness in the design. Advantages of this approach include the ability to nurture consensus among multiple definitions of trustworthiness, capture design rationale, evaluate qualitatively the extent of trustworthiness achieved, and maintain historical records of design decisions. We apply the NFR Approach to design a trustworthy Phoenix system, which is a message-oriented middleware system used by the US Air Force.
