Over the last century and a half, several new technology-based infrastructures have been created. They have been developed and used so extensively that they now partially characterize modern societies. Four of the most important infrastructures are built up around the core technologies of the internal combustion engine, aircraft, space flight, and radio and television. “Cyberspace”—defined as the Internet and other wide area networks based on computing and other information technologies (IT)—seems on its way towards becoming the latest such infrastructure. In little more than 30 years, cyberspace has become the locus of much value, notably in terms of information and money. Cyberspace can further be considered a means of passage, enabling extended personal and organizational presences and interactions. For a number of Organisation for Economic Cooperation and Development (OECD) member countries and global economic sectors, cyberspace has also become a locus for many systems that control and manage other more traditional infrastructures, such as those for banking and finance, emergency services, energy delivery, and many transportation and military systems. These computer communications networks are the underlying technological bases that will enable any and all “visions of the information society.”
