Embodiment 1

[0037] An embodiment of the present invention provides a method for safely clearing remaining information on a disk, including the following steps:

[0038] S11: Receive a request command to clear the remaining disk information, scan the directory and files in the file system that are about to perform a complete clear operation, and compare the scan result with the list of protected files. When it is detected that there is no file in the scan result in the list of protected files When, create to-be-cleared work task and message queue; Wherein, described message queue is used for loading the file information of scanning;

[0039] S12: Perform a thorough clearing operation on directories and files according to the created clearing task;

[0040] S13: Statistically analyze the cleaning results and create a result file.

Embodiment 2

[0042] Such as figure 1 As shown, the embodiment of the present invention provides a method for safely clearing the remaining information on the disk, including the following steps:

[0043] S21: Receive a request instruction for clearing the remaining disk information, scan the directory and files in the file system that are about to perform a thorough clearing operation, and compare the scanning result with the list of protected files. When it is detected that there is no file in the scanning result in the list of protected files When, create task and message queue to be cleared; Wherein, described message queue is used for loading the file information of scanning; When detecting the file in the scanning result in the list of protected files, then directly create the undeletable result file; It should be noted that a list of protected files needs to be created before performing this step;

[0044] S22: Perform a thorough clearing operation on directories and files according...

Abstract

The invention provides a method and a tool for safely clearing residual information of a disk and a production line system clearing method. The method for securely clearing the residual information ofthe disk comprises the following steps of: receiving a request instruction for clearing residual information of a disk, scanning a directory and files to be subjected to thorough clearing operation in the file system, comparing a scanning result with the protected file list, and creating a to-be-cleared work task and a message queue when it is detected that no file in the scanning result exists in the protected file list; wherein the message queue is used for loading scanned file information; according to the created clearing work task, executing a thorough clearing operation on the directoryand the file; and performing statistical analysis on the clearing result and creating a result file.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method, a tool, and a production line system clearing method for safely clearing remaining information on a disk. Background technique [0002] With the advancement of informatization, the security of information systems has become a matter of great concern to people. GB / T 22239-2008 "Basic Requirements for Information Security Technology Information System Security Level Protection" puts forward the requirement of "residual information protection" in information systems rated as level three and above. In order to meet the requirements for protection of remaining disk information, it should be ensured that the memory and storage space used by the virtual machine are completely cleared during recovery. [0003] For most systems or websites using the Linux operating system, the rm command is commonly used to delete sensitive files and directories, but this command o...
