specific Embodiment approach 1

[0037] refer to figure 1 and image 3 , specific implementation mode 1, a method for redirecting file operations in a security sandbox,

[0038] S1, the filter driver obtains the program interruption request sent by the A process, and judges whether the A process is a marked process stored in the process list, if yes, enters S2, if not, sends the program interruption request to the operating system;

[0039] S2, the filter driver judges whether the A process initiates the application program file operation, if yes, enters S3, if not, sends the judgment result to the operating system;

[0040] S3. The filter driver redirects the operation of the application file of the A process to the operation of the mapping file of the application file in the sandbox;

[0041] S4, the sandbox driver redirects the application program of the A process;

[0042] S4-1. The sandbox driver acquires the message that process A starts;

Abstract

The invention discloses a method and system for redirecting files through a security sand table, and relates to the field of software processing. The method comprises the following steps: S1, obtaining, by a filtering driver, a program interrupt request sent by a progress A, judging whether the progress A is a marked progress stored in a progress list, if the judging result is positive, entering step S2, and if the judging result is negative, sending the program interrupt request to a file system of the progress A; S2, judging, by the filtering driver, whether the progress A initiates an application program file operation or not, if the judging result is positive, entering step S3, and if the judging result is negative, sending the judging result to the file system of the progress A; S3, redirecting the application program file operation of the progress A to the operation of a mapping file of an application program file in a sandbox by the filtering driver; and S4, carrying out redirection operation on the application program of the progress A by a sandbox driver. According to the method and system, the problems that the same software in two different versions cannot coexist on the same computer system and the experience effect is bad as the users apply the existing sand table filtering method.

Description

technical field [0001] The invention relates to the field of software processing, in particular to a method and system for redirecting file operations in a security sandbox. Background technique [0002] When installing applications in the operating system, a large number of files will be released to the hard disk, and when uninstalling applications, these newly added files are often not completely deleted. Even if some existing junk file cleaning tools are used, the disk files cannot be guaranteed of purity. Moreover, since different versions of the software will release the same file at the same location on the disk during installation, the existing file will be overwritten by the new file, and the file cannot be completely isolated, resulting in two different versions. The same software cannot coexist on the same computer system. [0003] At the same time, due to the proliferation of malicious codes on the current network, there are many applications with malicious atta...
