一种面向攻击效果的网络安全态势评估方法

ttack amount and attack effect are two important factors to determine network security situation value. Numbers of methods based on attack amount factor have been put forward. These methods have reflected good results. On the other hand, attack effect factor is not considered fully.The paper introduces network security situation value formulas that are determined by attack amount factor based on a hierachical model. Then analyze attack effect to system. mend the above formulas in accordence with attack effect factor. Formulas that consider attack amount and attack effect will be obtained. A simulation test is done to validate that the mended formulas are fitter to practical situation.
