Abstract: In recent years the term "cyber" has been used to describe almost anything that has to do with networks and computers, especially in the security field. Another emerging field of study is looking at conflicts in cyberspace, including state-on-state cyber warfare, cyber terrorism, cyber militias etc. Unfortunately, however, there is no consensus on what "cyberspace" is, let alone what are the implications of conflicts in cyberspace. In order to clarify this situation, we offer the following definition: cyberspace is a time-dependent set of interconnected information systems and the human users that interact with these systems. We describe the background of the definition and show why this approach may be preferable over others. Specifically, we revisit the terms coined by Norbert Wiener (the father of cybernetics) and William Gibson. We show that time-dependence is an overlooked aspect of cyber space and make a case for including it in our proposed definition. In addition, we look at the implications that can be drawn from the time-dependence of cyberspace, especially in regard to cyber conflicts, which we define as a confrontation between two or more parties, where at least one party uses cyber attacks against the other(s). Specifically we review the implications on the potential for rapid deployments of offensive and defensive actions in cyberspace, the feasibility of mapping cyberspace, and the need for constant patrolling and reconnaissance.

1. Introduction
Every once in a while a new term comes along or an old term gets a novel meaning and suddenly it is everywhere. In recent years (decades, arguably), the word "cyber" has been added to a long list of words to create "new" terms. Examples of terms that surface in academic papers include cyber society (Lorents 2009), cyber attacks (Ottis 2008), offensive cyber capability (Ottis 2009), cyber defense, cyber warfare, cyber crime, cyber terrorism, etc. They all have something to do with the concept of cyberspace, which is often the presumed context or environment for the cyber concept in question. It follows that it is very important to have a good definition for cyberspace or the derived terms may become meaningless or flawed.
Below we review the origins of the term cyberspace and look at some of...
