Abstract

The invention provides a file protection method based on a Linux virtual file system, and the method comprises the steps: S1, carrying out the partitioning of a storage medium of a device, and dividing a writable operation area; S2, realizing write protection of a storage medium in an equipment driving layer, and reducing a writable range of the storage medium through independent configuration ofa writable operation area; S3, configuring a VFS security management module on the VFS layer; S4, setting a security mechanism enabling module on a user layer based on the steps S1 and S2; If the filesystem is not enabled, the VFS security management and control module does not perform any processing, and the whole file system is equivalent to a traditional Linux file system; And if a security mechanism is enabled, any operation on the file of the file system is processed by the VFS layer and the VFS security management and control module. The invention discloses a file protection method based on a Linux virtual file system.

Description

technical field [0001] The invention belongs to the technical field of Linux virtual file system protection, in particular to a file protection method based on the Linux virtual file system. Background technique [0002] The file protection technology of the operating system is an important basic technology in the field of information security, and plays an important role in the application of information security. In the field of security monitoring AI applications, the complex application environment and the storage and reading and writing of big data all pose higher technical challenges to the security of files. [0003] To ensure file security under the operating system, different file protection mechanisms are introduced. Commonly used protection technologies include protection based on storage media to protect files, but this method is suitable for read-only operating systems or requires frequent unprotection operations before big data analysis; there is also a securi...
