Several ways to lock the USB interface

Many companies do not allow employees to use the USB interface to copy the company's important files home. But how to easily and completely lock the USB interface is a difficult problem. Where is the difficulty? Difficult in the "both convenient and thorough" the six words above! What we can find on the net is the following methods:

Method One: Modify the Group Policy or registry

By modifying Group Policy or the registry, you can disable access to a USB flash drive for certain drive characters. But employees who know a bit about Group Policy and registry knowledge can easily remove the restrictions on the USB drive. So it's actually useless. The boss will not take this approach.

Method Two: Modify the BIOS settings, prohibit the use of USB devices

In the BIOS, set the USB device to disable. Then set a login password for the BIOS and the employee will not be able to use the USB stick. This is a very strong recruit, the boss is more satisfied. However, the USB mouse and USB keyboard are not available, which is unacceptable. Therefore, this trick is too ruthless, and no one will be used by the boss.

Method Three: Kill Windows comes with the USB device driver, so that the U disk inserted into the drive can not be found, nature will not be used.

Action: Remove the device package from the I386 folder in the window system completely, or deactivate the USB bus controller. The weakness of this approach is obvious: one cannot use a USB mouse and USB keyboard, and the other is that the master can reload the driver or enable the USB bus controller. In short, this precaution is also the ears of the deaf-furnishings!

Method Four: Microsoft official proposed a suitable for the expert operation solution. Specific ways to refer to Microsoft's Web page: HTTP://SUPPORT.MICROSOFT.COM/KB/823732/ZH-CN. But this method also has no effect, because the master can also do the opposite, the restrictions on the U disk are all canceled off. Therefore, this is only a way to prevent rookie can not prevent master.

The above four methods include all of the currently open lock USB storage interfaces, but there is no one way to be assured satisfaction. At present, almost all of the tool software can be found using one of the above methods to achieve, it is not reliable, the boss in the procurement of such software should be careful to be fooled by software vendors Oh!
