Security assessment method, device and equipment and computer readable storage medium

The invention discloses a security assessment method, device and equipment and a computer readable storage medium, and belongs to the technical field of data pushing. According to the security assessment method, the vehicle-road cloud system is divided into a subsystem level, a component level and the like, a hierarchical structure model is constructed, then the attack means quantized value of each component in a subsystem and the attack effect quantized value of each component are calculated, and the security assessment of the vehicle-road cloud system is realized based on the attack means quantized value and the attack effect quantized value. According to the method, the safety vulnerability level value of each component in a subsystem is calculated, the safety risk value of the subsystem is calculated according to the safety vulnerability level quantized value of each component, the safety risk values of all subsystems are added, the overall safety situation assessment value is calculated, and the elastic
