Device Control ensures the security of confidential data by restricting user access to devices that are installed on the computer or connected to it, including:
Data transfer tools (modems, external network cards)
Devices that are designed for converting data to hard copies (printers)
Connection buses (also referred to as simply "buses"), referring to interfaces for connecting devices to computers (such as USB, FireWire, and Infrared)
Device Control manages user access to devices by applying device access rules (also referred to as "access rules") and connection bus access rules (also referred to as "bus access rules").
