Problems solved by technology

[0005] However, the use of physical isolation also has its disadvantages. First of all, the current enterprise mobile office mainly uses laptops, and an additional hard disk and physical isolation card can only be customized by the manufacturer, which is not only expensive but also thick and inconvenient to carry.
Second: the capacity of the current laptop hard disk is generally too large, and the capacity of 1TB is very common. Adding an additional hard disk will cause a waste of hard disk resources.
Finally: Dual physical isolation needs to consider issues such as compatibility and switching between dual hard disks, and the adaptability is poor

Embodiment 1

[0046] In this embodiment, the system first needs to load the disk volume to obtain the disk volume information;

[0047]

[0048] This embodiment provides a processing flow of a disk isolation method as follows: figure 1 As shown, the following processing steps are included:

[0049] Step 11, by monitoring the volume, obtain the IRP request of the target disk accessed by the user received by each file system driver;

[0050] Before obtaining the IRP request of the target disk accessed by the user, it includes:

[0051] Create a control device object to be controlled by the application;

[0052] creating a source device object for said control device object;

[0053] Binding the source device object to the destination device object driven by the file system;

[0054] In this embodiment, the sFilter-based API framework runs in the form of a driver service. sFilter is the framework of Windows system file filtering. sFilter needs to process IRP requests, volume binding, a...

Embodiment 2

[0078] This embodiment provides a disk isolation system, and its specific implementation structure is as follows figure 2 As shown, it can specifically include the following modules:

[0079] Obtaining module 21, which is used to obtain the IRP request of the target disk accessed by the user received by each file system driver by monitoring the volume;

[0080] Judging module 22, which is used to judge whether the partition number of the target disk is in the white list of the isolated disk according to the IRP request;

[0081] Executing module 23, if yes, denying the user access to the target disk;

[0082] If not, allow the user to access the target disk.

[0083] A disk isolation system in this embodiment includes a creation module 20, which is used to obtain the IRP request of the target disk accessed by the user,

[0084] Create a control device object to be controlled by the application;

[0085] creating a source device object for said control device object;

Abstract

The embodiment of the invention provides a disk isolation method and system. The disk isolation method includes: acquiring an IRP request, of a target disk accessed by a user, received by various file system drive programs, by monitoring a volume; determining whether or not a partition number of the target disc is in a white list for disk isolation according to the IRP request; rejecting the user to access the target disk if so; and allowing the user to access the target disk if not. The disk isolation method and system can isolate and hide disk information of another operation system in the operation system without installing a hardware physical card by installing a self-defined drive program.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a disk isolation method and system. Background technique [0002] Single-machine dual-system is a dual-mode office system proposed for enterprise information office. It can provide two operating systems for employees' computers in the enterprise, one is a free operating system and the other is a working operating system. The two operating systems are required to be invisible and inaccessible to each other. Realize the isolation of dual-system hard disk resources. [0003] The existing single-machine dual-system disk isolation technology mainly uses dual physical hard disks, and an additional physical isolation card for dual hard disks is added. By controlling the hard disks and switching network cables, one hard disk is only valid for one network in the environment of internal and external networks. The physical connection is completely separated and there is no public st...
