基于自适应包标记的DDoS攻击源的定位研究

Research on locating of DDoS attackers based on adaptive parket marking

防御分布式拒绝服务攻击是当前网络安全中最难解决的问题之一。在自适应包标记的基础上,提出了有效计算攻击图各个路由器的本地发包率的方法,进一步提出了受害者重构攻击路径和定位攻击源的方法。受害者只要利用收集到的数据包就能更快更准的定位攻击源。

Defending against distributed denial of service attacks is one of the hardest security problems on the Intemet today. Based on the adaptive parket marking scheme, a method is proposed that can effectively compute the local traffic rate of each router in the attack graph. Furthermore, a method is presented which victims can reconstruct the attacking paths and locate the attackers. Victims can locate attackers more quickly and more truly only using the collected packets.
