Much has been made over recent years of the emerging threat of "cyber-attacks" on Western targets. Governments have become increasingly vocal on these threats, publishing a range of materials and proposing a number of policies. In the United States the government has taken steps which include the establishment of the US "Cyber-Command", alongside the US senate debating a so called "kill switch bill", which proposes to grant the president emergency powers over the internet. In the UK the cyber threat is also a growing concern. The recent Strategic Defence and Security Review and the UK National Security Strategy have both identified the sphere of "cyber Security" as a "Tier 1" threat or risk . Outside of government circles the issue is also becoming increasingly debated. Recently the popular periodicals "Foreign Affairs" and "The New Yorker" have both released articles detailing and debating the issue.

What however is the threat from this new "cyber domain", does it represent a new paradigm in warfare? Popular perceptions stemming from fictitious sources, such as the 2007 blockbuster Die Hard 4.0 in which the US comes under assault from "cyber-Terrorists" who target key infrastructure to cause a "fire sale" attack with potentially devastating consequences, suggest that cyber-warfare represents a devastating new strategic weapon capable of the kind of destruction only previously threatened by "WMD's". What's more the threat of cyber-attack is also characterised as being an emerging "asymmetric" threat. This idea of cyber-war is also lent credence from sources such as "Unrestricted Warfare," a proposal for Chinese military strategy, written by two Peoples Liberation Army colonels, whereby China seeks to beat a technologically and military superior opponent through the use of imaginative strategies which utilise measures that avoid direct military confrontation and instead attack their adversary through other avenues. Also adding to this perception of the cyber threat are the events like those in Estonia in 2007, where the Government and other sectors came under sustained denial of service attacks during a diplomatic spat with Russia over the relocation of "the Bronze Soldier of Tallinn". This and similar ideas certainly suggest that cyber-war does represent a threat in this way and this idea has been championed by American authorities on cyber-war. Richard A. Clarke, a former White House official with responsibility for the field, this year published "Cyberwar" a proposal for US strategy which prophesizes a particularly apocalyptic vision of a Chinese cyber-attack with mass casualties.
