Defence Minister Nick Harvey will be stressing the significance of the cyber attack threat to the UK in a speech at Chatham House today.
According to the BBC, Harvey is expected to tell the think tank that a laptop could be exploited to become as harmful a weapon as a cruise missile.
Last month, as part of the Strategic Defence and Security Review, prime minister David Cameron confirmed that the government would allocate £650m over a four-year period to fight against cyber attacks. The government also detailed cybercrime as a 'tier one' risk to Britain, alongside terrorism, international crises and natural hazards.
BBC defence correspondent Jonathan Beale said: "Mr Harvey will also outline plans to use cyber warfare to back up Britain's military capabilities by exploiting an enemy's weakness.
"He says in future the nation must win the battle in cyberspace as well as the battle on the ground."
Harvey is also expected to say that while the cyberspace can be useful and benefitical to members of the public, governments all over the world will have to protect their countries by establishing laws to govern the use of the internet and digital technology.
