Cyber Warfare is a broad term that defines a nation state sanctioned attack on a computer system of another country. One accomplishes this by means of hacking, computer viruses, and the like.

However, in some respects, cyber warfare is a hard term to fully define. Many often view the term itself is as a misnomer, due to the fact that a full out cyber war has not happened before. In fact, offensive cyber actions committed in history have been rejected and disavowed by those involved. Additionally, many experts question what full out cyber warfare would even look like.
