USB Port Read Only

[unclenelli]

Does anybody know if it is possible to make a USB port read-only?

I need to stop any data being written to any USB flash memory, but still need to be able to read from a flash memory.

Any ideas????

In hardware I don't know, but for Windows (SP2 and above) just change a registry key.

Start the registry editor (regedit.exe).
Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageD evicePolicies subkey. (Create the StorageDevicePolicies subkey if it doesn't already exist.)
From the Edit menu, select New, DWORD Value.
Type the name WriteProtect and press Enter.
Double-click the new value and set it to 1. Click OK.
Close the registry editor.
Restart the computer.Or you can use Thumbscrew - Thumbscrew: Software USB Write Blocker (http://www.irongeek.com/i.php?page=security/thumbscrew-software-usb-write-blocker) - to do it for you.

Obviously, anyone who knows the trick can reverse it, but for casual snoopers this may be enough. Hardly secure in the real sense though.

As Mac says. :ok:

If you are really serious about blocking writes, then you need a physical bridge device as relying on some software solution alone won't cut it. Example of a bridge device :
