Resource authority management method and system based on cloud platform

The invention provides a resource authority management method and system based on a cloud platform, belongs to the technical field of cloud platform management, and solves the problem of switching ofdifferent granularity authorities and different identity verification strategies of cloud platform resources. The method comprises the following steps: receiving an activation code input by a user, and switching to a fine-grained permission setting mode; after switching to the fine-grained permission setting mode, receiving a user ID, a target operation instruction and a sub-resource ID; wherein the user ID is an ID of a target user, and the target operation instruction is an operation instruction corresponding to a target operation; determining whether a preset access strategy is satisfied; and if so, executing a target operation of the target user on the to-be-operated sub-resources. According to the invention, access control of different granularities of resources can be carried out, and the resource safety and
