This fifth edition in the International Engagement on Cyber series focuses on securing critical infrastructure. The centrality of critical infrastructure in the Obama administration’s recent cybersecurity initiatives demonstrates the timeliness of this topic for greater review and scholarly input. In this manner, articles in this issue uncover the role and extent of international law and norms, public-private cooperation, as well as novel ways of conceptualizing ‘security’ in efforts to improve critical infrastructure cybersecurity. Other pieces provide case studies on the telecommunications, power, and energy sectors to generate an in-depth understanding of specific responses to security concerns in different infrastructure areas.

Additional contributions examine regulatory activities in cyberspace, the potential value of cryptocurrency, the evolution of cloud computing, cybersecurity in Brazil, as well as the integration of cyber in the military strategies of Russia, China, and the United States. The diversity of these topics demonstrates the Journal’s continued commitment to pursuing the myriad facets that compromise the field of cyber.

Please note, this special issue is not included in the subscription to the journal.

The Indian Ocean, with its critical routes for global commerce, is a potentially volatile location for geopolitical strife. Even as the region’s role in the international economy and as a highway to conflict zones increases, the US has failed to advance a coherent strategy for protecting its interests in the Indian Ocean or for managing complex diplomatic relationships across the region. The Indian Ocean and US Grand Strategy presents a range of viewpoints about whether and how the US should alter its diplomatic and military strategies for this region.

Contributors examine US interests in the Indian Ocean, assess the relative critical importance or imperiled nature of these interests, and propose solutions for American strategy ranging from minimal change to maximum engagement. The book concludes with a comparative assessment of these options and a discussion of their implications for US policymakers. This volume’s perspectives and analysis of the Indian Ocean region will be valued by scholars and students of US foreign policy, South Asia, and security studies as well as by diplomats, military officers, and other practitioners.
