1. Using electronic methods to knock out the command systems of a military enemy: Cyberwar involves the disruption or destruction of information and correspondence methods, broadly defined to include even military culture, upon which an adversary relies in order to know itself; that is, who it is, what it can do, when it can do it, and which threats to counter first.
2. Conducting, or preparing to conduct, military operations according to information-related principles: In cyberwars, there is an effort to know everything about one's opponent while keeping that enemy from knowing about the technical invasion.
