DDoS 攻击 Web 效劳环境的虚拟摘要分布式拒绝效劳(DDoS)攻击是当今网络平安领域最难解决的问题之一。其中重要的原因在于网络上大量不平安的机器的存在，其次是 DDoS 攻击工具的广泛可获得性以及攻击者通常采纳假冒的源 IP 地址。对于大型的网络来说，拒绝效劳攻击很可能会给企业造成巨大的麻烦，甚至造成企业网络的瘫痪。攻击发生时，攻击者短时间内向效劳器申请大量的连接，造成效劳器无法完成如此多的客户端连接请求，从而无法提供效劳。因此，讨论 DDoS 攻击及其对策是非常重要的。本文分析了 DDoS 攻击的攻击机制，攻击方法，常用 DDoS 攻击类型等，并在 web 效劳器上参加允许进入控制模块，成功配置了有效的 DDoS 攻击环境。对常用的三种 DDoS攻击方式进行了虚拟和讨论，分析了它们各自的优缺点。针对当前网络平安的缺乏和攻击类型的多样化，本文提出了一个攻击效果理想的DDoS 攻击 web 效劳环境的虚拟。这样，可以利用最少的资源获得最大程度的攻击强度。关键词：分布式拒绝效劳攻击；web 效劳；允许进入控制；会话控制机制DDoS Attack Web Server’s Environment VirtualAbstractDDoS attack is one of the most difficult problems in network security field. The most important reason is the being of many unsafe machines in network. DDoS attack tools abroad achieved and attack usually adopt cronk IP address. For large network, DDoS attacks are likely to give companies a huge trouble, and even caused the paralysis of the corporate network. When attack, the attacker to the server for a short period of time a large number of connections, causing the server could not be completed so many client requests, thus unable to provide services. So, research the DDoS attack and countermeasure is very important. This article analyses DDoS attack’s mechanism, method and the type that in common use. Also, we add the admission controller on the web server and successfully configures the most effect DDoS attack environment and can base on attack effect adjust attack stream. This article h...
