But the assurances of a military response tied to Article 5 are not easily converted to the digital world, Libicki said. <\/p>\n
\"In most categories of war, you have to defeat the other guy shooting back, but in the cyberworld you can do a lot just by building up your defenses,\" he said. \"When you put cyberwarfare into the template of conventional warfare, you end up drawing a lot of conclusions that don't make sense.\" <\/p>\n
But Dave Merkel, CTO of cybersecurity firm FireEye, said he isn't surprised by Friday's announcement, given the severe damage that can be caused by a cyberattack. Still, he said, governments may find it difficult to attribute the origin of a digital offensive. <\/p>\n

While both Libicki and Merkel agreed that many NATO members could determine the origin of an attack, those governments may not be eager to reveal their intelligence and technological capabilities. <\/p>\n
Yet even nongovernmental firms are sometimes able to positively identify cyberattacks: In 2013, Mandiant (since acquired by FireEye) released a report detailing a wide body of evidence that a Chinese government group had conducted a widespread cyber-espionage campaign. China denies engaging in cyber-espionage.<\/p>\n
NATO's biggest problem with enforcing a hard line against cyberattacks may simply be the wide proliferation of such warfare. <\/p>\n
A single hacker can launch hundreds of varied attacks in a short period of time, meaning that governments may find it nearly impossible to identify, attribute and respond to cyberstrikes in a timely manner, Merkel said. <\/p>\n
