近年来,网络攻击事件频繁发生。虽然还未出现国际法意义上的网络战争,但其破坏性后果不容小觑。面对网络战争这一新型战争形式,具备滞后性的传统战争法存在适用困境,其基本原则包括禁止使用武力原则与合法自卫原则、区分原则与比例原则、中立原则和维护中立国利益等面临适用困境。由此,本文分析并提供了解决该问题的两条思路:其一是调整现有国际法规范,即对传统战争法进行解释与调整;其二是制定新的国际法规范以适应新的需求。 In recent years, cyber attacks have occurred frequently. Although no cyberwar in the sense of international law has yet emerged, its destructive consequences should not be underestimated. In the face of the new form of war, such as the war on networks, the lagging traditional war law has its own applicable predicament. Its basic principles include the principle of the prohibition of the use of force and the principle of legal self-defense, the principle of distinction and proportion, the principle of neutrality, and the interests of the neutral countries. . Therefore, this article analyzes and provides two ideas to solve the problem: one is to adjust the existing norms of international law, that is, to explain and adjust the traditional law of war; the other is to formulate new norms of international law to adapt to new needs.
