Once we have looked at the security of the IT systems, we need to look at the vulnerabilities of the peripherals to see where they are vulnerable:

• Wireless keyboards/wireless mice: Wireless keyboards/wireless mice should not be used on secure systems as they are not encrypted and could easy be intercepted by a wireless packet sniffer.
• Displays: We need to ensure that we use display filters and do not have the displays facing outside windows. This is to prevent shoulder surfing.
• Wi-Fi enabled MicroSD cards: Wi-Fi enabled MicroSD cards have the same vulnerabilities as wireless keyboard and mice, where the data can be intercepted by a wireless packet sniffer.
• Printers/MFDs: Printers/multifunction devices are very vulnerable. For example, the printer may have data in the spooler waiting to be printed off and a scanner may have an image stored in their internal memory.
• External storage device: External storage devices normally operate with a USB interface and therefore are easy to steal data from. The best way to protect against data theft would be to use Bitlocker-to-go, which encrypts the whole drive, or use a self-encrypting device.
• Digital cameras: Digital cameras store information on memory cards that are very easy to remove from the camera. They may have pictures of documents that could be printed off very easily.
