Using proximity card readers instead of the traditional key punch doors would help to mitigate:
A. Impersonation B. Tailgating C. Dumpster diving D. Shoulder surfing
Answer: D
Explanation: Using a traditional key punch door, a person enters a code into a keypad to unlock the door. Someone could be watching the code being entered. They would then be able to open the door by entering the code. The process of watching the key code being entered is known as shoulder surfing.
Shoulder surfing is using direct observation techniques, such as looking over someone’s shoulder, to get information. Shoulder surfing is an effective way to get information in crowded places because it’s relatively easy to stand next to someone and watch as they fill out a form, enter a PIN number at an ATM machine, or use a calling card at a public pay phone. Shoulder surfing can also be done long distance with the aid of binoculars or other vision-enhancing devices. To prevent shoulder surfing, experts recommend that you shield paperwork or your keypad from view by using your body or cupping your hand.
