Critical infrastructures include sectors such as energy resources, finance, food and water distribution, health, manufacturing, government services and in some cases people. The consequences of an attack on one of these would result in loss of life, economic damage or a devastating effect on the operation of government services and military defence. In recent years, critical infrastructures have become increasingly more interconnected and are often connected to the Internet; consequently, this makes these systems more vulnerable and increases the threat of cyber-attack. In addition, the growing use of wireless networks means that infrastructures can be more vulnerable to direct attack than ever before.
