Embodiment 1

[0021] Embodiment 1, see Figure 4 As shown, the system of this embodiment includes: a process policy management module, a file filter driver module and a virtual disk driver module.

[0022] Wherein, the process policy management module is used to configure the process management policy;

[0023] Wherein, the file filtering driver module is used to filter various operation events of the original image file of the virtual disk and the virtual disk file after the image according to the configured process management strategy;

[0024] Wherein, the virtual disk driver module is used for converting the file system to the file pointed to by the filtered operation event.

Embodiment 2

[0025] Embodiment 2. In specific implementation, the above-mentioned process policy management module, file filter driver module and virtual disk driver module can be replaced by application layer management program, file filter driver program and virtual disk driver respectively. The system of this embodiment adds the process policy management part of the application layer and the file filter driver of the kernel layer on the basis of the existing system. see Figure 5 As shown, the specific system structure is mainly composed of three parts: application layer management program, file filter driver and virtual disk driver.

[0026] The GUI management program at the application layer interacts with users and is responsible for managing virtual disks, including creation and deletion of virtual disk instances, authentication of virtual disk usage, virtual disk images, and management of login accounts and permissions. And the process management strategy can be configured by the ...

Embodiment 3

[0030] Embodiment 3. Based on Embodiment 2, this embodiment describes the working principle of the system of the present invention in detail.

[0031] see Image 6 As shown, the GUI management program is composed of a GUI module, a virtual disk instance management module, a user management module and a newly added process policy management module. Among them, the GUI module is responsible for interacting with users in the form of window interface, including login interface, virtual disk instance management interface, user management interface, etc.; user management module is responsible for the configuration, loading and saving of users and their permissions; virtual disk instance management The module is responsible for the management of virtual disk instances, including functions such as adding, deleting, loading and unloading virtual disk instances. The loading and unloading of virtual disk instances sends relevant subcommands to the kernel layer virtual disk driver through...

Abstract

The invention discloses a system and a method for protecting virtual disk files, relates to the field of network safety and solves the problem that the prior art is short of efficient protection to the virtual disc original files and the imaged virtual disk files. The system comprises a process tactical management which is arranged for allocating a process management tactic, a file filter driving module which is arranged for filtering various operation events of the virtual disc original files and the imaged virtual disk files according to the allocated process management tactic, and a virtual disk driving module which is arranged for transforming the file system of the files pointed by the filtered operation events. The method comprises the steps of: allocating a process management tactic, filtering various operation events of the virtual disc original files and the imaged virtual disk files according to the allocated process management tactic, and transforming the file system of the files pointed by the filtered operation events.

Description

technical field [0001] The invention relates to the field of network security, in particular to a system and method for protecting virtual disk files. Background technique [0002] At present, the virtual disk technology has been widely used. For example, there have been a lot of realization tools such as virtual optical drives and virtual disks, which are mainly used to quickly install various (such as ISO, BIN, etc.) optical disk image files; There are also some implementation tools or commercial software similar to file safes, which use files as storage media and use virtual disk technology to map files to a virtual disk to achieve transparent file operations for users. [0003] see figure 1 As shown, the prior art solution is composed of two parts, the GUI (Graphical User Interface) management program of the application layer and the virtual disk driver of the kernel layer, wherein the GUI management program interacts with the user and is responsible for managing the vi...
