Kind Code:
A1
Abstract:
The present invention relates to the technical field of information security, and in particular to a method and apparatus for controlling a mobile storage device, and a computer-readable medium. A mobile storage device control system (200) comprises: an independently operated scanning apparatus (201), which is configured to scan a mobile storage device (20) and execute a specific operation on same, so that a file system log of the mobile storage device records the specific operation; and a control apparatus (202), which is configured to check whether the last record in the file system log in the mobile storage device (20) is the record of the specific operation, and if so, allow a user to access the mobile storage device (20), otherwise, forbid the user from accessing the mobile storage device. It is difficult for a file system log to be manipulated, and therefore, the control scheme is highly reliable. In addition, since only the last entry in the file system log is checked, the execution speed is fast, and less computing resources are occupied.
