Information Assurance and Cyberspace

Assurance may refer to:

Cyberspace is interconnected technology. The term entered the popular culture from science fiction and the arts but is now used by technology strategists, security professionals, government, military and industry leaders and entrepreneurs to describe the domain of the global technology environment. Others consider cyberspace to be just a notional environment in which communication over computer networks occurs. The word became popular in the 1990s when the uses of the Internet, networking, and digital communication were all growing dramatically and the term "cyberspace" was able to represent the many new ideas and phenomena that were emerging. It has been called the largest unregulated and uncontrolled domain in the history of mankind, and is also unique because it is a domain created by people vice the traditional physical domains.

Information is any entity or form that provides the answer to a question of some kind or resolves uncertainty. It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts. As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.
