With the increasing complexity of the system, showing the characteristics of highly complex functions, dynamic fault reconstruction and coupling correlation in various fields, the limitations of traditional reliability and security analysis methods are becoming more and more obvious. Relying on the rapid development of model-based systems engineering method (MBSE), reliability and security engineers put forward model-based security analysis method (MBSA) and model-based reliability analysis method (MBRA). This paper summarizes the research progress of MBSA from three aspects: how to integrate fault model and system model, how to improve the readability of safety analysis results and how to design appropriate safety analysis flow. This paper summarizes the research progress of MBRA from three aspects: how to improve the automation and scope of analysis tools, how to strengthen the adaptability of modeling language to reliability analysis, and how to construct mapping transformation rules between different models. Then the integrated analysis method of reliability and security based on model is introduced from two aspects: how to design a set of integrated analysis flow for security and reliability analysis and how to solve the interface problems among reliability model, security model and system model. Finally, the existing problems and future development direction in this field are described.
