DeviceLock allows network administrators to specify which users can access which devices (ports, floppies, MOs, etc.) on the local computer. Once DeviceLock is installed, administrators can assign permissions to LPT ports, CD-ROMs, COM Ports, or any other device, just as they would to any share on the hard disk. Network administrators may use DeviceLock to flush a storage device's buffers and to get extended information about devices and NTFS partitions.
