Randy wants to harden mobile devices used by his organization. Which of the following is not a typical mobile device hardening step?

Answer Options

A

Disable Bluetooth.

B

Use strong screen lock passwords.

C

Install software updates.

D

Jailbreak the device.

Correct Answer: D

Explanation

Jailbreaking is not a typical hardening process and is instead used to bypass device security to allow additional control of the device. While individuals may jailbreak devices, organizations rarely permit it. The NSA provides a guide to mobile device security practices at https://media.defense.gov/2021/Sep/16/2002855921/- 1/- 1/0/MOBILE_ DEVICE_BEST_PRACTICES_FINAL_V3%20- %20COPY.PDF, which includes many practices such as disabling Bluetooth, using strong passwords, and keeping device software up- to- date.
