Abstract: An operation defense method and device, apparatus and computer-readable storage medium are provided. The method includes: receiving an operation request from a business system through a shared interface; according to a parameter carried in the operation request, selecting at least one risk evaluation algorithm for the operation request from an algorithm rule library shared by a plurality of service systems; performing risk evaluation to the operation request with the selected risk evaluation algorithm; and according to a risk evaluation result, determining to allow the operation request. In the present application, a centralized operation defense mechanism is used to analyze the operation requests from different service systems and to select an appropriate risk evaluation algorithm to calculate the risk coefficient of each operation request, so that an operation with a high risk can be prevented, and a diffusion range of an abnormality can be reduced.
