Embodiment Construction

[0029] The invention provides a method for establishing a process-oriented virtual file system. The specific steps of the method are as follows:

[0030] The 1st, " process virtual file system configuration file " 100 of setting up process; The mapping relationship, permission relationship and extended access rules.

[0031] 2. Edit the mapping relationship between the directories and files of the "process virtual file system" 310 in the "process virtual file system configuration file" and the directories and files of the global file system 210 in the operating system (that is, the virtual directory 110 and the mapping directory 120 corresponding relationship), permission relationship and extended access rules.

[0032]The 3rd, need specify " process virtual file system configuration file " 100 when process runs, operating system builds " process virtual file system configuration table " 400 of this process in memory, and imports " process virtual file system configuration f...

Abstract

The invention discloses a building method of a virtual file system facing progresses, and belongs to the field of computers. The building method of the virtual file system facing the progresses includes that a progress virtual file system configuration files are built to store a mapping relation of a progress virtual file system and a global file system in an operation system; the progress virtual file system configuration files are appointed during a progress operation, a progress virtual file system configuration table of the progresses is built in internal storage by the operation system, and data of the progress virtual file system configuration files of the progresses are input; and the file operation of the progresses is converted into the operation of corresponding files of the global file system in the operation system through the mapping relation of the progress virtual file system configuration table. The building method effectively achieves logic or physics isolation of file systems among different progresses, therefore the damage degree of the global file system in the operation system by the progresses is reduced, and safety of the global file system is improved.

Description

technical field [0001] The invention belongs to the field of computers and mainly focuses on improving the safety of processes and operating systems. Background technique [0002] At present, the chroot method is mainly used to improve the security of the process and the operating system, and the process is limited to the designated directory of the global file system in the operating system, and all processes in the designated directory can be accessed according to the authority. This method is too extensive to control the files and directories that the process can access, and at the same time, it will limit the normal access requirements of the process if it is not handled properly. Contents of the invention [0003] The object of the invention is to provide a method for establishing a process-oriented virtual file system in order to improve the security of the process and the operating system. [0004] Different from the chroot method, the present invention does not li...
