Why there is a Need to Block USB Ports?

Employees have intimate access to company data and knowledge of internal systems. Without proper access control measures, data theft involves simply transferring it to a portable mass storage device such as a USB flash drive. The USB drive is capable of storing more than 1TB of data, which is more than enough for filtering databases, spreadsheets, design files, and any other intellectual property that needs to be protected.

Manual Process to Lock USB Through Registry

To do this, you need to enter your computer’s name. Let me warn you that if you do not manage the names correctly and end up changing the wrong ones, your computer will not start. Therefore, care must be taken when using REGEDIT.

Disable USB from registering:

  1. Open the Start menu and type “run” into the Run box.
  2. Enter regedit and press OK to open the Registry Editor.
  3. In the Registry Editor window, locate the following location:

HKEY_LOCAL_MACHINE > SYSTEM > Current Control Set > Services > USBSTOR

4.In the USBSTOR folder, doubleclick the Start button.

5. A new window will appear where you can change this registration value. 6. The default value is 3; change it to 4 and press OK. 7. Stop the Registry Editor and restart your System for the changes to take effect.

After restarting the computer, you will not be able to access the USB storage device via USB. To re-enable the USB, repeat the previous steps and reset the value to 3. This is the easiest way to block the USB port, but you need to be very careful with the Registry Editor .
