Question
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 the keypad 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.)
Options
- AThe risk of someone overseeing a pattern as a user enters the numbers is decreased.
- BThe routines to generate the random sequences are trivial to implement.
- CThis design makes entering numbers more difficult for users.
- DThe device needs to have additional power to compute the numbers.
- EEnd users will have a more difficult time remembering the access numbers.
- FWeak or easily guessed access numbers are more likely.

Explanation
A: Randomizing the keypad reduces the risk of shoulder-surfing attacks by eliminating predictable C: Randomization increases the cognitive load on users, making it harder to input numbers 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
