How to Set shared folder access permissions and Win7 shared folder Access Permissions
To protect the security of shared files, we need to set the shared folder access permission. This article uses win7 as an example to illustrate how to set the shared folder access permission for win7 to protect the security of shared files.
1. Set the access permission through the user account and shared file of the operating system.
Using the user account and file access permission configuration methods provided by the operating system to configure shared file access permissions is a common and effective method, and the operation settings are relatively simple, take Win7 as an example. The specific settings are as follows:
Before setting, make sure that your guest account is enabled. The method is as follows:
1. Open Control Panel-network and Internet-network and sharing center-change sharing advanced settings.
2. Find the public network configuration file.
3. Disable password sharing.
4. Select the disk to be shared. Property-sharing-advanced sharing.
5. Select Share this folder above.
6. Open the permission attribute of the folder. Select allow full control, apply and confirm.
So far, we have successfully completed the Win7 shared file access permission settings. In addition, the file sharing settings for Windows 2008 servers are similar and will not be described in detail.
2. Use dedicated shared folder management software to set shared file access permissions and control shared file access behavior.
Although the shared file access permission settings in the operating system allow you to configure the shared file access permission in more detail, if the file you share is important, you only want to allow users to read shared files and prohibit copying shared file content, saving shared files as a visitor's local disk, and printing shared files, you must use the dedicated shared folder management software and shared folder permission setting software, because the Shared File Permission settings of the operating system allow the client to copy the shared file content or save the shared file as a local file or print the shared file even if only the client has the read permission, therefore, shared files face the risk of being owned by visitors, which is not conducive to the protection of shared files. In particular, sharing files on servers is more important, often the company's intangible assets and trade secrets. Once leaked, it will cause significant losses to the company, therefore, effective measures must be taken to control access to shared files by LAN users, which must be achieved through dedicated shared folder management software.
At present, there are many similar shared folders in China, for example, there is a "share to shared folder management software" (: http://www.grabsun.com/gxwjjm.html) can easily set the access to shared files, it is easy to stop copying shared files, saving shared files as local files, or printing shared files. The principle is to encrypt the shared file to convert it to the EXE format. When opening the shared file, the client must double-click the shared folder in this EXE format, and finally access the shared file in the form of the shared file list box, which makes the access to shared files have effective restrictions, similar to a Baidu Library. As shown in:

Figure: shared files can only be accessed in the list box
You can use "Allow to shared folder management software" to set the access permissions for shared folders. This does not affect the permissions assigned to files shared by the operating system, it is another layer of protection barrier over the file sharing permission settings of the operating system. You can also add users and passwords for accessing shared files on your own, in addition, you can also prohibit the deletion of shared files, cut shared files, rename shared files, and so on by granting users the permission to modify shared files. This gives you more detailed control over shared file access permissions.
In addition, because shared file access is restricted in the shared file list box, you can prevent clients from cutting or dragging shared files to a local disk, in this way, you can prevent sharing files by means of USB flash drives, online storage, FTP uploads, and QQ files. This completely protects the security of shared files.
In short, you can set the access permissions for shared files through the user account and Shared File Permission configuration functions of the operating system, or through specialized shared folder management software, however, compared with the former, it is simpler, faster, and more accurate to control the access and use of shared files through dedicated shared folder permission setting software.
