USB Hack: Disable Writing to USB Drives

Written by Richard Blanchard on March 16th, 2007. Posted in Flash Storage, Security, USB Hacks, USB News

So here’s a poor mans USB hack to secure your network from unscrupulous characters downloading company secrets via USB.

In Windows XP SP2 and Vista you can disable writing to USB devices altogether by implementing a simple registry hack.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Control\StorageDevicePolicies] “WriteProtect”=dword:00000001

**Note: I inserted a break after …Set\< br>Control… to fit into post page.

Once done, reboot and you’re set. Make sure others don’t have Administrative rights, otherwise they could easily set things back. Here is the Vista error message upon copy attempt:
