通过分析目前DDoS(分布式拒绝服务攻击)带来的安全问题,结合网络防御部署中存在的问题和缺陷,提出一种智能分布式防御模型,并结合智能控制理论和遗传学原理,将自然生物系统的机理运用到计算机网络防御系统的设计中.该模型旨在全面提高网络用户整体的防护能力,以实现多层次的积极防御和对DDoS的综合防范.
This paper analyses the security problems by current DDoS attacks. Aiming at the existing problems and shortcomings of deployment of network defense, the paper proposes a model of intelligent distributed defense. Combined with the intelligent control theory and principles of genetics, an important natural biological system mechanism is applied to the systematic design of computer network defense. The model can be used to comprehensively improve the protective capability for overall network users in order to realize multi-level active defense and the integrated prevention to DDoS attacks.
