攻击判定

提出了一种基于网络流量自相似性Hurst系数的DDoS攻击判定条件本文在验证局域网流量具有严格自相似性的同时，对常用的Hurst系数计算方法进行了性能比较。

A decision condition of DDoS attack based on the Hurst parameter of network traffic self-similarity is presented . The performance of some common calculation methods of Hurst parameter is compared with the confirmation of the strict self-similarity characteristic of LAN traffic .

该文应用目标树来对分布式的较大规模的网络进行攻击判定，它能够有效地发现多步骤的复杂攻击和组合攻击。

The paper focuses on the application of Target Tree in combating the large-scale distributed attacks , which may effectively detect multiple-step complex and combined attacks .

主要改动：过去，由于怪物的攻击判定，只有相对比其他人高军衔的人才能玩侦查。

Major Changes : In the past , the recon was only available to players whose ranks were significantly higher than the other players in the game due to the hunting mechanics of the zombies on the map .

该模型综合考虑了主机访问诱饵的次数、访问的范围、事件发生的频率、访问的数据长度以及访问端口的性质等因素，较好地解决了网络攻击判定问题；
