This textbook presents a proven, mature Model-Based Systems Engineering (MBSE) methodology that has delivered success in a wide range of system and enterprise programs. The authors introduce MBSE as the state of the practice in the vital Systems Engineering discipline that manages complexity and integrates technologies and design approaches to achieve effective, affordable, and balanced system solutions to the needs of a customer organization and its personnel. The book begins with a summary of the background and nature of MBSE. It summarizes the theory behind Object-Oriented Design applied to complex system architectures. It then walks through the phases of the MBSE methodology, using system examples to illustrate key points. Subsequent chapters broaden the application of MBSE in Service-Oriented Architectures (SOA), real-time systems, cybersecurity, networked enterprises, system simulations, and prototyping. The vital subject of system and architecture governance completes the discussion. The book features exercises at the end of each chapter intended to help readers/students focus on key points, as well as extensive appendices that furnish additional detail in particular areas. The self-contained text is ideal for students in a range of courses in systems architecture and MBSE as well as for practitioners seeking a highly practical presentation of MBSE principles and techniques.

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.

Strategies for Protecting National Critical Infrastructure Assets eases the research burden, develops investigative protocols, and pulls together data into a comprehensive and practical guide, to help the serious reader understand advanced concepts and techniques of risk assessment with an emphasis on meeting the security needs of the critical national infrastructure. The text is divided into five major sections, which are further broken down by individual chapters, each addressing one element of risk assessment as well as focusing attention on applying the risk assessment methodology to a particular industry. This book establishes a new and acceptable approach for conducting risk assessments in a high-risk world. Helps the reader to understand advanced concepts and techniques of risk assessment Provides a quick, reliable, and practical "briefcase" reference to use in the office as well as on the road Introduces the elements of the risk assessment process by defining its purpose and objectives, describing the behavioural and physical sciences, the techniques employed in the process, and the measurement and evaluation tools and standards used to perform an objective risk assessment.

Describing OCTAVE (Operationally Critical Threat, Asset and Vulnerability Evaluation), a method of evaluating information security risk, this text should be of interest to risk managers.
