According to experts, the current crisis in the Middle East is not going to lead to a large-scale international war on land any time soon. But there is a chance that a new form of strategic attack could take place. A cyber attack. Modern Western society, especially in urban areas, has a vast number of critical infrastructures that provide electricity, water or gas. But it is as much about the supply of food or fuel as it is about communication structures and railways. If targets like these are hit by a so-called cyber attack, then that will have a major impact on our society.
