Terrorism
There is no universally accepted definition of terrorism. However, the United States Code of Federal Regulations defines terrorism as “...the unlawful use of force and violence against persons or property to intimidate or coerce a government, the civilian population, or any segment thereof, in furtherance of political or social objectives.” (28 C.F.R. Section 0.85)

Cyberterrorism
"Cyberterrorism" was coined in 1997 by Barry Collin, a senior research fellow at the Institute for Security and Intelligence in California, who defined it as the convergence of cybernetics and terrorism.
Mark Pollit, special agent for the FBI, defines cyberterrorism as "the
premeditated, politically motivated attack against information, computer
systems, computer programs, and data which result in violence against
noncombatant targets by sub national groups or clandestine agents."

Information Warfare (IW)
The rapid development of the discussion about Information Warfare has made the definition unclear.
The broadest definition simply equates Information Warfare with conflict in the information age, which makes the term too broad to have any use.
Another, more useful, definition outlines IW as a strategy for controlling one's opponent's perceptions using tools including armed force, diplomacy and propaganda as well as computer attacks.
Still narrower is the definition of IW as efforts to disrupt or exploit digital information infrastructures. Many states focus on this last definition and on digital information infrastructure defense. In this context, IW is often framed as a terrorism issue.
