'To create this omnibus collection, Romaniuk (Univ. of Alberta) and Manjikian (Regent Univ.) gathered the most comprehensive possible set of essays on national cybersecurity policies. Each of the 51 chapters provides an up-to-date summary and analysis of a single country's cybersecurity situation and strategies. Hostile-state actors, online terrorists, organized criminal groups, black hat hackers, and other bad actors all must be countered through sophisticated advance planning. Defenders are generally at a significant disadvantage against their nimbler attackers. Policies vary according to how each nation defines and prioritizes the potential threats. An authoritarian government, for example, will be far more concerned with controlling politically sensitive information that might undermine the power of the ruling regime than a more democratic nation. A maritime country is likely to prioritize different defenses than one that is landlocked. Countries that were once parts of the former Soviet Union fear hybrid warfare attacks that might be launched from Russia. Although the individual essays provide fine summaries of the unique laws, political forces, and social dynamics obtaining in each nation discussed, the book as a whole would have been greatly enhanced by expanding the editors' nine-page introduction to further integrate the themes drawn from these diverse contributions.Summing Up: Recommended. Upper-division undergraduates. Graduate students, faculty, and professionals.'--T. H. Koenig, Northeastern University, Choice, December 2022
