Cyberwar manual lays down rules for online attacks - Article Photos 1/1

A copy of the Tallinn Manual, a rulebook on cyberwarfare, is held up in a posed photograph in London, Tuesday, March 19, 2013. Even cyberwar has rules, and one group of experts is publishing a manual to prove it. The handbook due to be published later this week applies the venerable practice of international law to the world of electronic warfare in an effort to show how hospitals, civilians, and neutral nations can be protected in an information age fight.
