Win7 prohibits usb interface, win7 shield usb storage device use method

In the LAN of enterprises and institutions, sometimes in the need of operating system security and computer file security considerations, it is often necessary to disable the USB interface, especially to disable USB storage devices such as USB flash drives and mobile hard disks. However, since most computers now use USB mouse and keyboard, as well as non-USB storage devices such as U-Shield and USB printers for online banking, we can't disable non-USB storage devices such as USB mouse and keyboard while disabling USB storage devices. How to achieve it? There are two main methods:

First, prohibit the use of USB storage devices and prohibit the use of USB flash drives by disabling the installation of USB drivers, uninstalling the drivers of USB storage devices, and disabling the installation of large-capacity storage devices.

What is the prohibition of usb driver installation? It mainly prohibits the installation of external devices that have not installed the usb driver in the current computer. If the corresponding usb driver is installed, it will be invalid. This is a more practical function under the win7 system, which can prevent others from using it. Other usb external devices to operate on the current computer. Next u start Xiaobian to teach you a way to prohibit the installation of usb driver.

1, open the computer and open the “windows——inf” folder, then find "usbstor.pnf" in the inf folder and "usbstor.inf", here we are usbstor. Example of inf file: Move the mouse to the usbstor.inf file and right click. Click the “property item in the pop-up option, as shown below:

2, in usbstor In the .inf Properties window, select the “Security” tab and click on “ SYSTEM" in the group or user name and click on the “Edit” button as shown below:

3. In the permission window of usbstor.inf that pops up, click ""SYSTEM" in the group or user name, and then deselect the full control, click “apply ——determine&rdquo ; can be, as shown below:

Use the above method to change the permission of "usbstor.pnf" to the full control rejection state, restart the computer after completion, the original The usb external device used in the current computer can be used normally, if the usage is not in the setting right The usb external device before the limit state cannot be used. Disabling the usb driver installation can effectively prevent others from using other usb external devices to operate the current computer.

Second, prohibit the use of USB storage devices by special software that prohibits U disk use, shield USB interface software, and disable USB storage device software.

At present, there are many special softwares for prohibiting the use of USB flash drives and shielding USB storage devices in China, which makes it easier to disable the use of USB storage devices. For example, there is a “Block to USB port disable software” (download address: http://www.grabsun.com/monitorusb.html), you can automatically identify and automatically disable the USB storage device after installing it on your computer. (such as U disk, mobile hard disk, mobile phone and other devices with USB storage function), but does not affect non-USB storage devices (such as USB mouse and keyboard, U shield, USB printer, etc.), which can limit the use of USB storage devices the goal of. As shown below:

Figure: Disable the USB interface by using the USB disable tool software.

At the same time, you can use only the specific U disk by "Large-to-USB shielding software". Only certain U disk can be used; only files can be copied from the U disk to the computer and files can not be copied from the computer to the U disk, or the password can be copied from the computer to the U disk.

In addition, through the "big trend to USB monitoring software", you can also prohibit the sending of email attachments, prohibit the uploading of computer files to the network disk, prohibit the sending of files through FTP tools, prohibit QQ from sending files, and prohibit QQ groups. Sharing file uploads, etc., can prevent the leakage of computer files through the network, and further protect the security of computer files.

In short, regardless of the way to disable USB driver installation, uninstall USB driver, disable USB storage device through Group Policy, disable U disk usage in the registry, and disable USB interface software through special shielded USB port software. Other methods can achieve the purpose of prohibiting the use of USB storage tools, but the more complete and flexible computer USB storage tools can be disabled through the special USB control software and USB shielding software. And management, specific measures, enterprises and institutions can make choices according to their own needs.
