简介:

  详细介绍了网络战的现状,并警告我们现在已经进入了新的由国家力量支持的网络战争的军备竞赛之中。目前,每个人都理所应当地认为各个国家都拥有国家级网络武器,它们正在变得更 加高端复杂,从监听侦查行为向破坏行为发展。
  全球网络暗战正在升温,而赌注也不再局限于电脑的虚拟世界。现在 ,部分由爱德华·斯诺登公布的秘密文件曝光了美国情报机构正致力于准备网络战争,除了花费数十亿美源来采集和分析这个世界大部分国家的电子通信,还涉及网络战争、远程控制、植入性病毒、黑客攻击与反攻击等。
  20 世纪,科学家们发明了所谓的“ABC武器”—原子(atomic)武器、生物(biological)武器和化学(chemical)武器。人们花了几十 年来部署和调节这些武器。现在,新的“D武器”—数字(digital)武器将战争带入互联网时代,几乎没有任何国际公约或者监管机构可以监控这些“D武器”的使用,所以,优胜劣汰是“D武器”的唯一法则。比如作为第一个被完整记录下来的网络武器,它仍然是有史以来最出名的网络武器。Stuxnet蠕虫病 毒可以无需借助网络连接进行传播,这种病毒可以破坏世界各国的化工、发电和电力传输企业所使用的核心生产控制电脑软件,并且代替其对工厂其他电脑“发号施 令”。虽然大多数感染看上去都发生在伊朗,但是这些网络攻击像是打开了一个潘多拉的盒子,现在美国媒体经常报道自己的关键基础设施很容易就遭到报复和攻击。
