Prohibit computer sharing files, group policies prohibit shared folders, and disable network sharing
To disable file sharing on a computer:
 
Method 1: Cancel file sharing through the sharing settings of the operating system. The specific method is as follows:
 
Right-click the shared folder, click the share tab, and select "do not share" to cancel file sharing.

Of course, if you still need to share files at work, you can set a password to access shared files, which enhances the security of shared files and prevents arbitrary access to shared files. Method: Right-click the shared folder, select "properties", switch to "share", and click "network and sharing center" below, as shown in:

Select "enable password protection sharing" in "password protection sharing", as shown in:

In this way, we can set a password for shared files to prevent unauthorized access to shared files.
 
Method 2: special computer security management software and shared file access control software are used to prohibit computer sharing and file sharing.
 
Although you can set a password for the shared file to protect the security of the shared file, you can also re-enable the shared file at any time through reverse setting, or even cancel the shared file access password, in this way, you can access shared files at will. Therefore, for the sake of security, it can also be achieved through specialized computer security control software and shared file monitoring software.
 
For example, there is a USB-to-USB control system (: http://www.grabsun.com/monitorusb.html), is a comprehensive protection of computer file security software, just after the computer installation, you can completely disable the use of USB storage devices such as USB flash drives, mobile disks, and mobile phones, without affecting the use of non-USB storage devices (such as USB mouse, keyboard, and dongle ). At the same time, you can also prohibit computers from sending emails, uploading files from online storage, sending files via QQ, and uploading FTP files to fully protect the security of computer files.
In the disabled software for connecting to the USB port, a "prohibit file sharing" function is integrated. You only need to check the option to disable the computer from setting shared files, at the same time, if the local machine has shared files, it can also be automatically canceled, which greatly protects the security of shared files. As shown in:

After this setting, you can completely disable the computer from setting shared files, and disable files already shared by the Local Machine in real time, thus greatly protecting the security of computer files.
 
In addition, the software disabled from the USB port is hidden based on the background. You need to enter a password to call the software. In addition, many protection functions are provided for key locations of the operating system, in this way, the security of the operating system is greatly protected, and some technical staff are prevented from modifying operating system settings without authorization to re-share files. This completely achieves file sharing security protection, protects computer file security.
 
In short, whether through the relevant settings of the operating system or by using third-party software can achieve the management of computer shared files, the specific method used by enterprises and institutions can choose according to their own needs.
