Effective Model-Based Systems Engineering


Book Description

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.




Cybersecurity Ops with bash


Book Description

If you hope to outmaneuver threat actors, speed and efficiency need to be key components of your cybersecurity operations. Mastery of the standard command-line interface (CLI) is an invaluable skill in times of crisis because no other software application can match the CLI’s availability, flexibility, and agility. This practical guide shows you how to use the CLI with the bash shell to perform tasks such as data collection and analysis, intrusion detection, reverse engineering, and administration. Authors Paul Troncone, founder of Digadel Corporation, and Carl Albing, coauthor of bash Cookbook (O’Reilly), provide insight into command-line tools and techniques to help defensive operators collect data, analyze logs, and monitor networks. Penetration testers will learn how to leverage the enormous amount of functionality built into nearly every version of Linux to enable offensive operations. In four parts, security practitioners, administrators, and students will examine: Foundations: Principles of defense and offense, command-line and bash basics, and regular expressions Defensive security operations: Data collection and analysis, real-time log monitoring, and malware analysis Penetration testing: Script obfuscation and tools for command-line fuzzing and remote access Security administration: Users, groups, and permissions; device and software inventory




A Fierce Domain


Book Description

Even in its earliest history, cyberspace had disruptions, caused by malicious actors, which have gone beyond being mere technical or criminal problems. These cyber conflicts exist in the overlap of national security and cybersecurity, where nations and non-state groups use offensive and defensive cyber capabilities to attack, defend, and spy on each other, typically for political or other national security purposes. A two-year study, resulting in the new book -- A Fierce Domain: Cyber Conflict, 1986 to 2012 -- has made the following conclusions, which are very different from those that policymakers are usually told: Cyber conflict has changed only gradually over time, making historical lessons especially relevant (though usually ignored). The probability and consequence of disruptive cyber conflicts has been hyped while the impact of cyber espionage is consistently underappreciated. The more strategically significant the cyber conflict, the more similar it is to conflict in the other domains ? with one critical exception.




At the Nexus of Cybersecurity and Public Policy


Book Description

We depend on information and information technology (IT) to make many of our day-to-day tasks easier and more convenient. Computers play key roles in transportation, health care, banking, and energy. Businesses use IT for payroll and accounting, inventory and sales, and research and development. Modern military forces use weapons that are increasingly coordinated through computer-based networks. Cybersecurity is vital to protecting all of these functions. Cyberspace is vulnerable to a broad spectrum of hackers, criminals, terrorists, and state actors. Working in cyberspace, these malevolent actors can steal money, intellectual property, or classified information; impersonate law-abiding parties for their own purposes; damage important data; or deny the availability of normally accessible services. Cybersecurity issues arise because of three factors taken together - the presence of malevolent actors in cyberspace, societal reliance on IT for many important functions, and the presence of vulnerabilities in IT systems. What steps can policy makers take to protect our government, businesses, and the public from those would take advantage of system vulnerabilities? At the Nexus of Cybersecurity and Public Policy offers a wealth of information on practical measures, technical and nontechnical challenges, and potential policy responses. According to this report, cybersecurity is a never-ending battle; threats will evolve as adversaries adopt new tools and techniques to compromise security. Cybersecurity is therefore an ongoing process that needs to evolve as new threats are identified. At the Nexus of Cybersecurity and Public Policy is a call for action to make cybersecurity a public safety priority. For a number of years, the cybersecurity issue has received increasing public attention; however, most policy focus has been on the short-term costs of improving systems. In its explanation of the fundamentals of cybersecurity and the discussion of potential policy responses, this book will be a resource for policy makers, cybersecurity and IT professionals, and anyone who wants to understand threats to cyberspace.




Realizing the Potential of C4I


Book Description

Rapid progress in information and communications technologies is dramatically enhancing the strategic role of information, positioning effective exploitation of these technology advances as a critical success factor in military affairs. These technology advances are drivers and enablers for the "nervous system" of the militaryâ€"its command, control, communications, computers, and intelligence (C4I) systemsâ€"to more effectively use the "muscle" side of the military. Authored by a committee of experts drawn equally from the military and commercial sectors, Realizing the Potential of C4I identifies three major areas as fundamental challenges to the full Department of Defense (DOD) exploitation of C4I technologyâ€"information systems security, interoperability, and various aspects of DOD process and culture. The book details principles by which to assess DOD efforts in these areas over the long term and provides specific, more immediately actionable recommendations. Although DOD is the focus of this book, the principles and issues presented are also relevant to interoperability, architecture, and security challenges faced by government as a whole and by large, complex public and private enterprises across the economy.










Cyberspace and National Security


Book Description

In a very short time, individuals and companies have harnessed cyberspace to create new industries, a vibrant social space, and a new economic sphere that are intertwined with our everyday lives. At the same time, individuals, subnational groups, and governments are using cyberspace to advance interests through malicious activity. Terrorists recruit, train, and target through the Internet, hackers steal data, and intelligence services conduct espionage. Still, the vast majority of cyberspace is civilian space used by individuals, businesses, and governments for legitimate purposes. Cyberspace and National Security brings together scholars, policy analysts, and information technology executives to examine current and future threats to cyberspace. They discuss various approaches to advance and defend national interests, contrast the US approach with European, Russian, and Chinese approaches, and offer new ways and means to defend interests in cyberspace and develop offensive capabilities to compete there. Policymakers and strategists will find this book to be an invaluable resource in their efforts to ensure national security and answer concerns about future cyberwarfare.
