Risk assessment method and device for asset sample in network, and storage medium

The invention discloses a risk assessment method and device for asset samples in a network, and a storage medium. The method comprises the steps: obtaining evaluation index values of a plurality of to-be-evaluated asset samples in the network under all sub-class evaluation indexes in a risk assessment system; establishing a first evaluation index value set with the maximum risk and a second evaluation index value set with the minimum risk; according to the obtained index values and the index value set, calculating the calculation weight of each sub-class evaluation index by using a grey correlation analysis method in combination with an entropy evaluation method, and further calculating the weight of each mother-class evaluation index; calculating a risk value of each asset sample under each parent class evaluation index according to the obtained index value, the index value set and the weight; and calculating a total risk evaluation value of each asset sample according to the risk value of each asset sample
