Abstract

The invention discloses a mobile storage system access control method and device supporting a service security mark. The method comprises the following steps: 1) setting a service security mark of themobile storage system, and marking the service security attribute of the mobile storage system, wherein the service security mark of the mobile storage system comprises a security level and a servicecategory; 2) when the mobile storage system is accessed to a computer environment, acquiring a service security mark of the computer environment and performing matching check on the service securitymark of the computer environment and the service security mark of the mobile storage system; if the two service security marks are matched, allowing the mobile storage system to access the computer environment; otherwise, prohibiting access to the computer environment. According to the invention, the access control and data management and control capabilities of the mobile storage system are greatly improved.

Description

technical field [0001] The invention relates to a mobile data storage system access and data control method and device, in particular to a data storage system supporting business security marks and storage and access methods, which belong to the field of computer technology. Background technique [0002] At present, in order to improve the security of mobile storage media, corresponding security measures are mainly taken in aspects such as access authentication, access control, and data encryption. However, the existing mobile storage devices cannot identify whether the computing environment it accesses has the same or higher security level, and cannot prohibit the storage of data higher than the security level of the mobile storage device. It is difficult to provide fine-grained Data management and control capabilities. Contents of the invention [0003] Aiming at the problem that the current security-hardened mobile storage system does not support access environment con...
