移动互联网远程分布式攻击目标检测仿真

Target Detection Simulation of Remote Distributed Attack In Mobile Internet

对移动互联网远程分布式攻击目标进行检测,能够有效保证互联网的安全性,提高互联网运行稳定性。对移动互联网远程分布式攻击目标的检测,需要根据攻击目标行为概率分布,得到攻击行为下的观察矩阵,完成互联网分布式攻击目标的准确检测。传统方法结合攻击目标威胁性指数分析法,给出远程攻击目标路径,但忽略了对攻击行为下的观察矩阵的获取,导致检测结果精度偏低。提出基于攻击效用的移动互联网远程分布式攻击目标检测方法。构建基于攻击意图的远程分布式攻击目标逻辑关系图,刻画入侵者在攻击目标过程中实现每步攻击获得的收益大小。依据远程分布式攻击目标行为概率分布、关联规则法获得攻击目标行为状态转移矩阵以及观察矩阵,对移动互联网远程分布式攻击目标意图进行挖掘,检测下一步攻击目标。实验结果表明,所提方法能够有效提高检测的精度以及加速比。

In traditional methods, the observation matrix under attack behavior is ignored, which causes the low accuracy of detection. Therefore, a method for detecting the remote distributed attack target in mobile Interuet based on attack effectiveness is proposed. The logic diagram of remote distributed attack target is constructed based on attack intention. In the process of attacking target , earnings of invaders in each step of attack are described. According to probability distribution and association rule of remote distributed attack target behavior, the state transition matrix and the observation matrix are obtained, then remote distributed attack intention in mobile Internet is mined and next attack target is detected. Simulation results show that the proposed method can effectively improve the detection accuracy and speed-up ratio.
