The Pentagon has laid out ambitious plans for working with Silicon Valley entrepreneurs to defend the US in the internet age, outlining plans to create a cyber guard and to test new computer programmes in a “cyber range” as it attempts to stop hackers from compromising national security.
Although they stopped short of saying that a cyber-attack on the US’s security systems would amount to a declaration of war, military leaders said that the US reserved the right to use “whatever response is appropriate”.
In its first, long-awaited cyber strategy, unveiled on Thursday, the defence department confirmed that cyberspace is the fifth domain of warfare – alongside air, land, sea and space.
