CompTIA Security+ (SY0-501) — Question 975

A company is allowing a BYOD policy for its staff.
Which of the following is a best practice that can decrease the risk of users jailbreaking mobile devices?

Answer options

• A. Install a corporately monitored mobile antivirus on the devices.
• B. Prevent the installation of applications from a third-party application store.
• C. Build a custom ROM that can prevent jailbreaking.
• D. Require applications to be digitally signed.

Correct answer: D

Explanation

Requiring applications to be digitally signed ensures that only verified and trusted software can be installed, thereby reducing the likelihood of jailbreaking. The other options, while helpful, do not directly prevent users from jailbreaking their devices as effectively as enforcing digital signatures.
