DeviceLock is an excellent tool for network administrators that need to lock out unauthorized users from using USB and FireWire devices, WiFi and Bluetooth adapters, CD-Rom and floppy drives, serial and parallel ports and many other plug-and-play devices. Once DeviceLock is installed, administrators can control access to any device, depending on the time of day and day of the week. The USB white list allows you to authorize only specific devices that will not be locked regardless of any other settings. The intention is to allow special devices (e.g. smart card readers) but lock all other devices. The Media White List feature allows you to authorize access to specific DVD/CD-ROM disks, uniquely identified by data signature, even when DeviceLock has otherwise blocked the DVD/CD-ROM drive.

Once completed, you can generate a report concerning the permissions that have been set and see which users have been assigned for which device and what devices are on the USB white list on all the computers across your network. If you're not a network administrator, I don't advise touching this program without a through reading of the instructions because you can end up locking yourself out! However, generally DeviceLock provides a high level of security with an interface that is well integrated into Windows Group Policy Editor. If you've had problems with people using illegal devices on your company network, it's the answer to your prayers.
