CISA Practice Question: A multinational corporation is implementing a…
A multinational corporation is implementing a bring your own device (BYOD) policy. Which of the following is the most important security control to ensure corporate data is protected on employee devices?
⚠ Common exam trap
Watch out — candidates often confuse full-device encryption (Option C) as sufficient for BYOD, failing to recognize that encryption alone does not provide data segregation or selective wipe capabilities, which are essential for protecting corporate data on a device the organization does not fully own.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement mobile device management (MDM) with containerization.
Mobile Device Management (MDM) with containerization creates a separate, encrypted workspace on the employee's device that isolates corporate data from personal data. This ensures that the organization can enforce security policies (e.g., remote wipe, access controls) on the corporate container without affecting the user's personal information, which is critical for BYOD environments where full-device control is not feasible.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Require employees to install antivirus software.
Why it's wrong here
Antivirus is important but does not fully separate or control corporate data.
- ✗
Prohibit the use of personal devices for work.
Why it's wrong here
This is a restrictive policy that may not be feasible in a BYOD environment.
- ✗
Mandate full-device encryption.
Why it's wrong here
Full-device encryption protects data at rest but does not provide granular control or separation of corporate data.
- ✓
Implement mobile device management (MDM) with containerization.
Why this is correct
Correct. Containerization segregates corporate data and enables selective wipe without affecting personal data.
