【摘要】：针对当前攻击图在大范围网络应用中具有时间复杂度以及图形化描述不准确等缺陷,提出了一种基于智能化状态转移以及权限改进的攻击图构建方法:采用智能化状态转移途径构建攻击模型,依据该模型规划相应的攻击图,并在攻击图生成中引入了权限改进体制,该方法以主机间的连接分析为依据,根据网络攻击状态图中不同主机的原始权限,获取攻击权限的改进路径,能够针对网络变换情况调整主机的权限,进而确保相应网络的安全性,针对大规模复杂化网络攻击问题构建有效的攻击图,以确保整体网络的安全性和高效性。通过最终的仿真实验可得,该方法构建网络攻击图的时间较短,具备较低的时间复杂度和较高的扩展性,是一种高效的攻击图构建方法。
[Abstract]:In view of the time complexity and inaccurate graphical description of the current attack graph in large-scale network applications, and so on, In this paper, an attack graph construction method based on intelligent state transition and authority improvement is proposed: the attack model is constructed by intelligent state transition approach, and the corresponding attack graph is planned according to this model. In addition, the authority improvement system is introduced in the attack graph generation. Based on the analysis of the connection between hosts, the improved path of attack authority is obtained according to the original permissions of different hosts in the network attack state diagram. In order to ensure the security and efficiency of the whole network, the authority of the host can be adjusted according to the situation of network transformation, and the security of the corresponding network can be ensured, and the effective attack graph can be constructed to solve the problem of large-scale complex network attack. Through the final simulation experiments, it is found that the proposed method has shorter time, lower time complexity and higher expansibility, so it is an efficient attack graph construction method.
