The invention discloses a device capable of carrying out safety management on a universal storage medium. The device, which is bridged between a host and a storage medium driver and is completely transparent to both ends, is used for performing storage safety management strategy set by individuals or organizations. When in work, the device is independent of the software environment of the host, and supports centralized safety management on the storage medium in organizations. The device is utilized as a master mode to exchange data with the storage medium driver and is utilized as a slave mode to exchange data with the host, aiming at implementing the storage safety management strategy during data exchange process. The hardware part of the device comprises a master mode port, a slave mode port and storage safety management treatment. The software part of the device comprises data exchange treatment between the master mode and the slave mode and storage safety management. If a uniform safety strategy management server is arranged in an organization to cooperate with the use of the device, centralized safety management can be carried out on the storage medium in the organization.
