基于强度系数的内部网络攻击图研究
Research on internal network attack graph based on strength coefficient
摘要
Abstract
At present,the main indicator for attack graph of network is the cost of an attack,and it is assumed that cost and benefit are independent of each other,and quantitative analysis of the correlation among these key elements is ignored.In order to solve this problem,firstly,this paper defined an internal network attack model based on state transition.It introduced a strength coefficient to quantitatively analyze the relationship between the attack complexity and the risk value of display.Then it gave a realization method of the above variable to analyze the relationship between the attack complexity and the risk value of display.Secondly,based on this variable,the improved generation algorithm for attack graph was used to obtain the optimal cost.Finally,the simulation experiment shows that the new attack graph is more concise and more intuitive,in addition,the attack graph can also reflect the reality of the attack process.关键词
