With the release of Windows XP SP2, you can now secure those USB Flash Memory devices.
When the USB devices first hit the scene, there were a lot of people (primarily those in the security field) who were ready to cast voodoo spells on the devices. Why?
The Flash Memory devices were another chink in the security armor. Users could insert the devices into their USB port, and take company data with them or inadvertently upload viruses they brought from home. Even though the devices have become popular over the last year or so (I simply can't live without one), there still wasn't a way of making sure they were not a security risk.
Windows XP SP2 enables users to make these devices Read-only by adding a specific registry value. Under HKEY_LOCAL_MACHINE\System\CurrentControlSet\
Control\StorageDevicePolicies, there's now a value called WriteProtect.
If the data value is set to 0 (zero), write-protect is disabled. If the data value is set to 1 (one), then write-protect is enabled, effectively making the USB Flash Memory device Read Only.
So, to make it simple:
Value Name (DWORD): WriteProtect
Data Value: 0 = disable, 1 = enable
You can script this with your favorite script editor and use your favorite distribution tool to send it to everyone in the company. Of course, I would recommend SMS 2003, but GPO or a Login Script would do it, too.
