In Trusted Extensions, administrators control access to local peripheral devices such as tape drives, CD-ROM drives, USB devices, printers, and microphones. Access can be granted on a user-by-user basis. The software restricts access to peripheral devices as follows:
By default, devices must be allocated for use.
You must be authorized to access devices that control removable media.
Remote users cannot use local devices such as microphones or CD-ROM drives. Only local users can allocate a device.
