Peripherals
For Network Peripherals we will be looking for Hardware that is not (directly) connected to the network.
Devices like these are attached -- temporarily or permanently -- to a component of the network.

Device's like this could ba hardware like:

• Bar Code Reader (1D and 2D)
• Cell phones
• Digital camera(s)
• Docking station(s)
• Hand Held Computing Devices (inc.: PDAs, inventory taking, etc.)
• Keyboards
• Local printers
• Microphones
• Monitors / Displays
• Mice
• Speakers
• Removable storage devices (inc.: USB memory sticks, external harddisk, floppies, CDs, DVDs, etc.)
• USB Hubs
• VoIP phone handsets

Some of such peripherals are potential points-of-failure of the security infrastructure.
To limit those potential there must be policy, procedure and process for reducing risk and/or exposure of these devices..
