Each spring, the Cyber Project at Georgetown University’s Institute for Law, Science, and Global Security convenes a conference of leading international experts from academia, the private sector, and government to address cutting-edge issues in cybersecurity. The 2014 annual conference is the starting point for this special issue of the Georgetown Journal of International Affairs, the fourth volume in the annual International Engagement on Cyber series. Key papers from the conference have been included in this issue along with new articles added to round out this collaboration between the Cyber Project and the journal. This issue begins with a group of articles under the theme “A Post-Snowden Cyberspace,” describing how Edward Snowden’s revelations directly or indirectly changed the way the global community understands cybersecurity and cyber law. Other topics covered include cyber weapons, cyber deterrence, Japan’s cybersecurity strategy, data protection in the private sector, executive accountability for data breaches, minimum security standards for connected devices, and the problem of underinvestment in cybersecurity. Please note, this special issue is not included in the subscription to the journal. The Georgetown Journal of International Affairs is the official publication of the Edmund A. Walsh School of Foreign Service at Georgetown University. Each issue of the journal provides readers with a diverse array of timely, peer-reviewed content penned by top policymakers, business leaders, and academic luminaries.
