System Monitor

System monitor refers to the keystroke logger, which is a hardware device or small program that monitors each keystroke a user types on a specific computer's keyboard. As a hardware device, a keystroke logger is a small battery-sized plug that serves as a connector between the user's keyboard and computer. Because the device resembles an ordinary keyboard plug, it is relatively easy for someone who wants to monitor a user's behavior to physically hide such a device "in plain sight."
