2、TURE, AND ENVIRONMENTiii Preface Cyber incidents have been increasing in frequency and cost in recent years, with some resulting in hundreds of millions of dollars in losses. There is marked variability from study to study in the estimated direct and systemic costs of cyber incidents, which is furth
3、er complicated by the considerable variation in cyber risk across countries and industry sectors. In many cases, comparing research studies is complicated by a lack of transparency in methodologies, assumptions, and data sets used. The goal of this research was to produce a transparent methodology f
