A more useful definition of cyber waris hostile action in cyberspace whose effects amplify or are equivalent to major physical violence. In the physical world, governments have a near-monopoly on large-scale use of force, the defender has an intimate knowledge of the terrain, and attacks end because of attrition or exhaustion.
网络战争更为有用的定义是网络空间中发生的敌对行动，其所产生的影响放大或者等同于严重身体暴力。现实世界中，政府近乎垄断了大规模的武力使用，防守方更加熟悉地形，而进攻则可能因为消耗或疲劳而结束。资源和流动性都非常昂贵。
