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.
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.
For more than three hundred years, the world wrestled with conflicts that arose between nation-states. Nation-states wielded military force, financial pressure, and diplomatic persuasion to create "world order." Even after the end of the Cold War, the elements comprising world order remained essentially unchanged. But 2012 marked a transformation in geopolitics and the tactics of both the established powers and smaller entities looking to challenge the international community. That year, the US government revealed its involvement in Operation "Olympic Games," a mission aimed at disrupting the Iranian nuclear program through cyberattacks; Russia and China conducted massive cyber-espionage operations; and the world split over the governance of the Internet. Cyberspace became a battlefield. Cyber conflict is hard to track, often delivered by proxies, and has outcomes that are hard to gauge. It demands that the rules of engagement be completely reworked and all the old niceties of diplomacy be recast. Many of the critical resources of statecraft are now in the hands of the private sector, giant technology companies in particular. In this new world order, cybersecurity expert Adam Segal reveals, power has been well and truly hacked.
Explaining cybercrime in a highly networked world, this book provides a comprehensive yet accessible summary of the history, modern developments, and efforts to combat cybercrime in various forms at all levels of government—international, national, state, and local. As the exponential growth of the Internet has made the exchange and storage of information quick and inexpensive, the incidence of cyber-enabled criminal activity—from copyright infringement to phishing to online pornography—has also exploded. These crimes, both old and new, are posing challenges for law enforcement and legislators alike. What efforts—if any—could deter cybercrime in the highly networked and extremely fast-moving modern world? Introduction to Cybercrime: Computer Crimes, Laws, and Policing in the 21st Century seeks to address this tough question and enables readers to better contextualize the place of cybercrime in the current landscape. This textbook documents how a significant side effect of the positive growth of technology has been a proliferation of computer-facilitated crime, explaining how computers have become the preferred tools used to commit crimes, both domestically and internationally, and have the potential to seriously harm people and property alike. The chapters discuss different types of cybercrimes—including new offenses unique to the Internet—and their widespread impacts. Readers will learn about the governmental responses worldwide that attempt to alleviate or prevent cybercrimes and gain a solid understanding of the issues surrounding cybercrime in today's society as well as the long- and short-term impacts of cybercrime.
Assesses the current state of information security (IS) in the fed. gov't. It delineates the serious IS weaknesses that place critical operations and assets at risk and outlines actions needed to further improve security practices in gov't. Focuses on the Dept. of Vets. Affairs and the Social Security Admin., which illustrate the types of risk facing departments and agencies as well as actions required to strengthen security mgmt. Recent efforts by these org's. and others throughout gov't. are encouraging because they signify increasing attention to IS concerns, but additional measures are necessary to develop and maintain an effective IS mgmt. program.
