众所周知，当一个主权国家的领土、领海、领空受到外敌侵犯时，陆、海、空三军将履行抵御外敌保卫祖国的神圣使命。然而，在当今计算机网络蓬勃发展的年代里，一个国家的计算机网络空间——领网，也是国家主权的一个标志，它与领土、领海和领空具有同样重要的经济、政治和军事? As we all know, when the territory, territorial waters and airspace of a sovereign state are violated by foreign enemies, the troop movements of land, sea and air will perform the sacred mission of defending the motherland against foreign enemies. However, in today’s booming computer networks, the network space of a country, a network of neighbors, is also a sign of national sovereignty. It has the same economic, political and military significance as territories, territorial waters and airspace.
