Cyberspace is a part of daily life for businesses, government officials, and everyday people to some extent. It has made life fast, transparent, and simple at the expense of risks. Hence, experts working in cyberspace not only develop user applications, but also focus on developing policies, procedures, and mechanisms to provide security cover for the applications. This book, an edited volume by J. Martín Ramírez and Luis A. García-Segura, tries to outline the various risks and benefits of cyberspace.

This book has 18 chapters arranged into three parts: “Cyberspace,” “Cybersecurity,” and “Cyberwarfare.” Part 1, “Cyberspace,” has six chapters covering topics such as how cyberspace helps researchers, its importance in various walks of life, how developing countries deploy cyberspace, how business units are handling cyberspace, and how individuals and groups are using cyberspace. The six chapters in this part almost cover the basics of cyberspace. Chapters 4, 5, and 6 are especially interesting. Chapter 4 talks about the digital divide between developing and developed countries. This chapter specifically addresses how human development is connected to digitization, and presents a survey from the United Nations Development Programme (UNDP).

Part 2, “Cybersecurity,” has seven chapters. Various case studies are presented, including organized crime in the European Union and United Nations, money laundering, tax havens, bank secrecy, and various mechanisms to handle these problems. Specific focus is also given to cybersecurity 3.0 and how terrorists use cyberspace; how to handle these issues, from both technical and legal points of view, is also presented.

Part 3, “Cyberwarfare,” has five chapters. One of the chapters presents salient points from Tallinn manual on international law applicable to cyber warfare [1]. Other chapters in this part focus on cyber operations and international armed conflicts, the role of international humanitarian law (IHL) in cyberspace, various cyber strategies followed in different countries, and various cyber attacks against nuclear facilities.

The editors were reasonably successful at arranging the chapters; however, they should have numbered the chapters and sections within the chapters to improve readability. A few duplications appear here and there, which are normally unavoidable in an edited volume. Overall, this book has very good information on various aspects of cyberspace and will be useful for graduate students, researchers, lawmakers, and practitioners who work in cybersecurity.
