Method for controlling access to cloud disk on basis of Hook technology

The invention discloses a method for controlling access to a cloud disk on the basis of the Hook technology. The method comprises the steps that an access control policy allocation module is in charge of collecting cloud disk access control strategies allocated by an administrator, and issuing the cloud disk access control strategies to an access control protection module of each client side; after a cloud disc mounting disc drive informing module is mounted on a cloud disk client side, and the access control protection module is informed of the mounted disc drive name; the access control protection module controls file operations carried out in the corresponding cloud disc drive according to the received cloud disc access control strategies and the received drive name. The method for controlling access to the cloud disk on the basis of the Hook technology has the advantages that protection is carried out on files in the specific cloud disc drive through the Hook technology, the operation processes such as reading, copying, moving and renaming of the files are protected by allocating credible processes and credible expanded names in a combination mode, and the grounding safety problem of cloud terminal files is solved; meanwhile, logs are kept for operations in the cloud disc drive, post audit can be carried out conveniently.
