【摘要】：研究快速构建网络攻击节点分布图的问题。针对网络攻击范围越来越大,攻击种类越来越复杂,在进行大范围攻击节点搜索的过程中,受到攻击种类和数量增大的影响,攻击源激发和原子筛选的时间复杂度越来越高。传统的网络攻击节点分布图构建模式,受到上述问题影响,构建分布图的时间复杂度极高,造成入侵检测结果不准确。为了提高检测准确率,提出了一种利用攻击原子约束分类的优化网络攻击图构建方法。利用攻击原子约束分类方法,获取网络中的攻击节点,从而为网络攻击图构建提供准确的数据基础。利用差分网络攻击原子定位方法,对攻击网络原子进行定位,获取准确的网络攻击路径,实现网络攻击图的快速构建,保证入侵检测的准确性。实验结果表明,利用改进算法进行网络攻击图构建,能够有效降低网络攻击节点分布图的时间复杂度。
[Abstract]:This paper studies the problem of quickly constructing the distribution map of network attack nodes. In view of the increasing range of network attacks and the increasing complexity of attack types, the attack types and the number of attacks are increased in the process of searching for large scale attack nodes. The time complexity of attack source excitation and atomic screening is increasing. The traditional network attack node map construction mode is affected by the above problems, and the time complexity of constructing distribution map is very high. The result of intrusion detection is inaccurate. In order to improve the detection accuracy, an optimized network attack graph construction method using attack atom constraint classification is proposed. The attack nodes in the network are obtained by using the attack atom constraint classification method. In order to provide the accurate data basis for the network attack graph construction, the differential network attack atom location method is used to locate the attack network atom, obtain the accurate network attack path, and realize the fast construction of the network attack graph. The experimental results show that using the improved algorithm to construct the network attack graph can effectively reduce the time complexity of the network attack node distribution map.
