摘　　要：提出了一种基于云模型的主机安全评估方法,方法全面考虑影响主机安全的连续型及离散型因素,设计了一套完整的指标因素集,并把离散参数加入云的不确定推理器,改进了单纯依靠连续型参数进行评估的推理算法.通过推理算法可以实现云的不确定性评估,解决评估知识表达的不确定性,实现定性概念与定量数据之间的不确定性转换,为用户提供可靠的决策信息,并且通过实验仿真验证了方法的可行性.A method of host security assessment based on cloud model was presented in this paper.The continuous and discrete factors affecting host security were comprehensively considered,a set of complete index factors set were designed,and the discrete parameters were added into the cloud of uncertain reasoning,the reasoning algorithm based on the evaluation of continuous parameters were improved.This reasoning algorithm can realize uncertainty assessment,solve the uncertainty in assessment knowledge representation,and achieve the uncertainty conversion between qualitative concept and quantitative data,can provide reliable decision-making information to the user,through experiment simulation to verify feasibility of the method.
