In this paper, we propose a network security situation prediction model for CMS based on Evidential Reasoning (ER) and Hierarchical Belief Rule Base (HBRB). First, the factors affecting the cybersecurity status of CMS are analyzed, an assessment framework is established, and the ER algorithm is fused to derive the security posture value of CMS. Second, a cybersecurity posture prediction model for cloud manufacturing systems based on HBRB was constructed to avoid the combinatorial explosion problem caused by too many attributes. In addition, a Whale Optimization Algorithm (WOA) is used to optimize the parameters in the prediction model. The model can make full use of uncertain and semi-quantitative information, which solves the incompleteness of expert knowledge and improves the accuracy of this prediction model.展开更多
