The Emerging Risks Initiative of the Chief Risk Officers Forum is pleased to announce the publication of a new position paper called Critical Information Infrastructure. In industrialised societies, computers are interconnected to form a complex communication mesh, characterised by common hubs servicing dispersed users. This interconnectivity is called “network infrastructure”. The rapid transmission and processing of data, using network infrastructure, is critical to the well being of both producers and consumers. Network failure has the potential for serious economic and social impacts. We hope you will find this paper both informative and helpful in managing Critical Information Infrastructure risks.
