Military News reports "Surprisingly, sorting out the rules connected with all-out cyber war has picked up considerable steam. A little more than a month ago, a gathering of officials from more than a dozen countries including China and Russia agreed to apply international law on warfare to cyber."
"But coming to agreement on the more pervasive threat — constant cyber intrusions emanating from China — is proving far more challenging. Even defining the difference between intrusion and attack gets thorny. It’s one of the areas playing a key role in the ongoing dialogue between the two countries on the issue, an issue that contains definitional disagreements, cultural standards, and even technical ambiguity."
