Embodiment Construction

[0030] The present invention relates to a system and method for operating a file-aware unified file system in a computer system. More specifically, the present invention relates to a method and system for operating a unified file system that takes into account the unified policy of the unified file system, and since each branch is unified to the unified file system, at the same time Consider the security requirements of each branch of the computer system. When an application program accesses the unified file system, the present invention also considers the security requirements of each branch and the unified policy of the unified file system. Further, since the present invention is compatible with existing branch policies of files and directories of each branch to be unified, the present invention supports the execution of module security policies or modules that have been unified into each file and / or directory in the unified file system Require.

Abstract

The invention discloses a system and method for operating a unification file system within a computer system that takes into account the security requirements of each file system as each file system is unified into the unified file system. As the invention is compatible with existing run time policies of files and directories within each file system that is to be unified, the invention supports the enforcement of security policies or requirements of each file and / or directory that has been unified into the unified file system.

Description

technical field [0001] The present invention relates to a system and method for operating a file-aware unified file system in a computer system. Background technique [0002] Currently, a computer system uses a file system to manage files stored in storage devices such as hard drives, solid state disks, and memory cards. Most file systems (also known as branches) organize directories in a hierarchical or tree-like format. For example, the most basic directory in this type of branch is the root directory, which has multiple subdirectories accordingly. Each of said subdirectories in turn has its own subdirectory. As subdirectories increase, the size of the hierarchical tree expands accordingly. Each file stored in the file system is typically referenced by a pathname specifying a hierarchical sequence of directories to reach the file. For example, a file "example.txt" referred to by a path name such as " / directory1 / backup / example.txt" is stored in a directory named "backup...
