The Pentagon has finally released its much anticipated strategy for handling cyber attacks and protecting its necessary infrastructure and computer networks from them, and because the document stresses that the military is vulnerability to attack in this arena, it confirms what many have thought for some time – cyberspace, after, air, land, sea, and space has become the fifth domain of warfare.
The document does not say that if the United States security systems were cyber attacked this should be viewed and acted upon as if it were physical conflict but stresses that this kind of act can be just as dangerous as any in the physical world of bullets and bombs.
United States Deputy Secretary of Defence William Lynn, who revealed that 24,000 files with defense data were stolen when a contractor’s computer was hacked in March, said: “In the 21st century, bits and bytes can be as threatening as bullets and bombs.”
Mr. Lynn explained that a nation-state employed a foreign intelligence service to initiate the attack on the contractor, but he would not talk about how the U.S. responded to the incident, what information was stolen, or what country was involved.
