Arming for Virtual Battle: The Dangerous New Rules of Cyberwar

Some are especially concerned that the Tallinn proposals could also make it possible to expand the rules of the "war on terror." The authors have incorporated the call of US geostrategic expert Joseph Nye to take precautions against a "cyber 9/11" into their manual. This would mean that the superpower could even declare war on organized hacker groups. Combat drones against hackers? Cologne expert Kress cautions that the expansion of the combat zone to the laptops of an only loosely organized group of individuals would constitute a "threat to human rights."

Germany's military, the Bundeswehr, is also voicing concerns over the expansion of digital warfare. Karl Schreiner, a brigadier general with the Bundeswehr's leadership academy in Hamburg, is among those who see the need for "ethical rules" for the Internet battlefield and believe that an international canon for the use of digital weapons is required.

Military leaders must rethink the most important question relating to defense in cyberspace: Who is the attacker? "In most cases," the Tallinn manual reads optimistically, it is possible to identify the source of data attacks. But that doesn't coincide with the experiences of many IT security experts.

The typical fog of cyberwar was evident most recently in the example of South Korea. At first, officials said that DarkSeoul was clearly an attack from the north, but then it was allegedly traced to China, Europe and the United States. Some analysts now suspect patriotically motivated hackers in North Korea, because of the relatively uncomplicated malware. That leaves the question of just who South Korea should launch a counterattack against.

The South Korean case prompts Cologne international law expert Kress to conclude that lawyers will soon have a "new unsolved problem" on their hands -- a "war on the basis of suspicion." Translated from the German by Christopher Sultan
