ITPEC IP April 2020 Question 44
ITPEC IP April 2020 — Question 44 of 100

Why not others:
- updating the OS mitigates software vulnerabilities
- disabling location services limits location disclosure
- a strap reduces dropping or snatch theft
- none of these prevents another person from visually reading the screen
Key rule: Shoulder surfing is visual information theft, so countermeasures must shield the display or the user's input from observation.
