In the post-9/11 context, security issues have become increasingly central to the hosting of sport mega-event (SMEs). Security budgets for events like the Olympic Games now run into billions of dollars. This article seeks to advance the emerging field of SME security research in substantive and analytical terms. We identify three sets of issues and problems that are taking shape within this field: first, comparative issues in relationship to the Global North and Global South, notably given the growing number of SMEs set to be staged in the Global South; second, various risks and security strategies that are specific to different SMEs, including perceived terrorist threats, spectator violence, and broader risks associated with poverty, social divisions, and urban crime; and third, the security legacies that follow from SMEs, such as new surveillance technologies, new security-focused social policies, and security-influenced urban redevelopment. We argue that future research into SME security governance should be underpinned by a synthetic theoretical framework. This framework brings together three particular strands: first, a sociological approach that explores the _security field,_ drawing in part on Bourdieu; second, critical urban geographical theory, which contextualizes security strategies in relationship to new architectures of social control and consumption in urban settings; and third, different strands of risk theory, notably in regard to reflexive modernization, governmentality, and cultural sociological questions.
