Abstract

Problem Solved: This software program blocks the user from using USB Removable Flash Disk Drive in windows environment. This software tool continuously monitors the windows registry key and blocks the windows from detecting/identify the USB Removable Disk Drives. Existing Solution: To DISABLE the detection of USB removable disk drive, in windows XP and 2000, follow the steps below 1. Click Start, and then click Run. 2. In the Open box, type regedit, and then click OK. 3. Locate, and then click the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor 4. In the right pane, double-click Start. 5. In the Value data box, type 4, click Hexadecimal (if it is not already selected), and then click OK. 6. Quit Registry Editor. To RE-ENABLE a disabled detection of USB removable disk drive, follow these steps below 1. Click Start, and then click Run. 2. In the Open box, type regedit, and then click OK. 3. Locate, and then click the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor 4. In the right pane, double-click Start. 5. In the Value data box, type 3, click Hexadecimal (if it is not already selected), and then click OK. 6. Quit Registry Editor The above solution is also stated in the Microsoft’s link/section: http://support.microsoft.com/kb/823732#LetMeFixItMyself The above solution applies to below operating systems. • Microsoft Windows XP Home Edition • Microsoft Windows XP Professional • Microsoft Windows 2000 Advanced Server • Microsoft Windows 2000 Professional Edition • Microsoft Windows 2000 Server • Microsoft Windows Server 2003, Enterprise Edition • Microsoft Windows Server 2003, Standard Edition And some software tools are available in the market which uses the same mechanism as mentioned in the Microsoft’s link or uses the windows user group policies which will be applied to the user profiles to disable this default feature of windows. Draw Back of the Existing Solution: As this existing solution is known to most of the IT professionals, as the process is reversible any users can update the windows registry keyword value to re-enable or change the profile policy to re-enable the automatic detection of USB Flash drives in windows. And applying the user group policy and changing the setting manually in every system is not an easy task for the network administrator. So the additional protection is required to overcome the above draw back and some kind of monitoring mechanism is required in the operating system, so that operating system will not identify/ detect the presence of USB Floppy disk drive.
