Abstract

As the Department of Defense (DOD) formulates strategy and doctrine for operating in cyberspace, it is vital to understand the domain and how it relates to the traditional domains of land, sea, air, and space. While cyberspace has distinct technologies and methods, it shares many characteristics with the traditional domains, and some of the conventional wisdom about how cyberspace differs from them does not hold up under examination.
