With nations becoming increasingly susceptible to cyber-attacks, the British government is holding a conference to address the growing threat.

The conference, being held in London's foreign ministry office - itself a target of a sustained cyber-attack - aims to have nations work together to combat international cyber crime. Rather than the credit-card numbers and online log-ins most people subject report stolen, nations stand to have large amounts of bureaucratic and even security information stolen.

The British government has seen digital attempts to steal IT, defence and energy data. For the Baltic state of Estonia, the cost of a recent cyber-attack could have been even greater as it saw its entire government structures compromised.
