While there are a multitude of terrorist typologies, this chapter focuses on two in particular because of their relationship with globalisation: state terrorism and dissident terrorism. It discusses how terrorism is both a product of, and a reaction to, globalisation. All around us are signs of the responses to the terrorist threat: body scanning at airports, surveillance equipment, bollards to prevent cars driving into crowded malls, increased security for sporting events and other public gatherings where large numbers of people gather. The way the notion of risk permeates society on a global scale has arguably been forever altered after the terrorist attacks of 9/11, when the Twin Towers of the World Trade Center in New York were brought down by hijacked planes. In terms of terrorism carried out on its own soil, Australia has been relatively fortunate, but it has been the planned target of some major terrorist attacks.
