A kind of access control list setting method and system

Abstract

The application discloses an access control list setting method. The method comprises the following steps: finding timestamps of all nodes under a current parent directory and an access control list version number, wherein the nodes under the parent directory include corresponding sub-directories and files; screening a node marked with a newest timestamp and a newest access control list version number through comparison to obtain a screened node; and setting an access control list of the screened node on the current parent directory, and then correspondingly updating the timestamp and the access control list version number on the parent directory. Through adoption of the access control list setting method provided by the application, time for setting the parent directory access control list can be shortened effectively, and the setting speed is increased. Moreover, the application also correspondingly discloses an access control list setting system.

Description

technical field [0001] The invention relates to file storage technology, in particular to an access control list setting method and system. Background technique [0002] In recent years, the permission control method of access control list (ACL) has been widely used in network security prevention and protection, such as using access control list to control the access permission of storage files on the server, so as to protect the security of network resources in the server. [0003] When using the access control list method to set file permissions, not only set the file owner permissions, group permissions, and other permissions, but also grant different access permissions to different users, such as the same file through the access control list method You can grant read permission to user A and write permission to user B. [0004] From the above introduction to the access control list method, it can be known that this method can establish an access permission table for eac...

AI Technical Summary

Problems solved by technology

[0004] From the above introduction to the access control list method, it can be seen that this method can establish an access permission table for each file to record the permissions that different users can access the file. When setting the access control list for a directory, it is necessary to use a recursive method to set the access control list for the subdirectories and files in the large directory one by one. This setting method will take a lot of time
