Many people have listed seven principles, such as single duty principle, opening and closing principle, Richter substitution principle, dependence inversion principle, interface isolation principle, composite reuse principle and Dimit principle.

On the other hand, although DDoS can erode bandwidth or resources and force service interruption, this is far from the real purpose of hackers. As the saying goes, there is no killing without buying and selling. DDoS is only a nuclear weapon in the hands of hackers. Their purpose is either extortion, commercial competition or political stance. Driven by this kind of black interest, more and more people take part in this industry and improve and upgrade the attack methods, resulting in DDoS becoming more and more fierce in the Internet industry and becoming a persistent disease that cannot be overcome worldwide.
