Cyber vandalism and identity theft represent enormous threats in a computer-driven world. This timely work focuses on security issues with the intent of increasing the public's awareness of the magnitude of cyber vandalism, the weaknesses and loopholes inherent in the cyberspace infrastructure, and the ways to protect ourselves and our society. The nature and motives behind cyber attacks are investigated, as well as how they are committed and what efforts are being undertaken to prevent further acts from occurring. This edition explores security issues also in the world of social networks. General security protocols and best practices have been updated to reflect changes in the cyber world, and the changing business information security landscape is analysed in detail.

The frequency of new editions of this book is indicative of the rapid and trem- dous changes in the fields of computer and information sciences. First published in 1995, the book has rapidly gone through three editions already and now we are in the fourth. Over this period, we have become more dependent on computer and telecommunication technology than ever before and computer technology has become ubiquitous. Since I started writing on social computing, I have been ad- cating a time when we, as individuals and as nations, will become totally dependent on computing technology. That time is almost on us. Evidence of this is embodied in the rapid convergence of telecommunication, broadcasting, and computing devices; the miniaturization of these devices; and the ever increasing storage capacity , speed of computation, and ease of use. These qualities have been a big pulling force sucking in millions of new users every day, sometimes even those unwilling. Other appealing features of these devices are the increasing number of applications, apps, as they are increasingly becoming known, and being wireless and easily portable. Whether small or big, these new gizmos have become the c- terpiece of an individual's social and economic activities and the main access point for all information. Individuals aside, computing technology has also become the engine that drives the nations' strategic and security infrastructures that control power grids, gas and oil storage facilities, transportation, and all forms of national communication, including emergency services.

This textbook highlights the essential need for a strong ethical framework in our approach to teaching of and working in computer, information and engineering sciences. Through thought-provoking questions and case studies, the reader is challenged to consider the deeper implications arising from the use of today’s rapidly evolving computing technologies and ever-changing communication ecosystems. This thoroughly revised and updated third edition features revised chapters with new and updated content and hardened the ethical framework. To cope with the rapidly changing computing and telecommunication ecosystem, a new chapter, Ethics and Social Responsibility in the Metaverse, has been added. The interface between our current universe and the evolving metaverse presents a security quagmire. The discussion throughout the book is candid and intended to ignite students’ and professionals’ interest and active participation in discussions of the issues we are facing now and those likely to emerge in the near future.  Topics and features—including fully updated content: Introduces a philosophical framework and tools for understanding and analyzing computer ethics in personal, public, and professional spheres Describes the impact of computer technology on issues of security, privacy, anonymity, and civil liberties Discusses the security and ethical quagmire in the platforms of the developing metaverse (NEW chapter) Examines intellectual property rights in the context of computing, including the risks and liabilities associated with software Discusses such key social issues in computing as the digital divide, employee monitoring in the workplace, and risks to physical and mental health Reviews the history of computer crime, and the threat of digitally facilitated bullying, harassment, and discrimination Considers the ethical challenges arising from online social networks, mobile telecommunication technologies, virtual reality, the Internet of Things and 5G technologies Includes learning objectives, discussion questions and exercises throughout This concise and accessible work addresses the critical ethical and moral issues important to all designers and users of computer technologies.

If we are to believe in Moore's law, then every passing day brings new and advanced changes to the technology arena. We are as amazed by miniaturization of computing devices as we are amused by their speed of computation. Everything seems to be in ? ux and moving fast. We are also fast moving towards ubiquitous computing. To achieve this kind of computing landscape, new ease and seamless computing user interfaces have to be developed. Believe me, if you mature and have ever program any digital device, you are, like me, looking forward to this brave new computing landscape with anticipation. However, if history is any guide to use, we in information security, and indeed every computing device user young and old, must brace themselves for a future full of problems. As we enter into this world of fast, small and concealable ubiquitous computing devices, we are entering fertile territory for dubious, mischievous, and malicious people. We need to be on guard because, as expected, help will be slow coming because ? rst, well trained and experienced personnel will still be dif? cult to get and those that will be found will likely be very expensive as the case is today.
