A security analyst is designing a touch screen device so users can gain entry into a locked room by touching buttons numbered zero through nine in a specific numerical sequence. The analyst designs thekeypad so that the numbers are randomly presented to the user each time the device is used. Which of the following best describes the design trade-offs? (Select two.)
Correct Answer: A,C
Step by Step
A: Randomizing the keypad reduces the risk of shoulder-surfing attacks by eliminating predictable patterns.
C: Randomization increases the cognitive load on users, making it harder to input numbers quickly.
D: Additional computational power is minimal and not typically a trade-off.
E and F: Remembering access numbers or weak passwords are unrelated to keypad randomization.
