ISC2 CC Practice Question: Implements a bring-your-own-device (BYOD) policy
An organization implements a bring-your-own-device (BYOD) policy. Which security control is most important to enforce in the BYOD policy?
⚠ Common exam trap
ISC2 often tests the misconception that a single technical control (like encryption or passwords) is sufficient for BYOD security, when the real exam focus is on centralized management and the ability to enforce and revoke policies remotely via MDM.

Correct answer & explanation
✓
Implement mobile device management (MDM) for remote wipe and policy enforcement
Mobile device management (MDM) is the most important control for a BYOD policy because it provides centralized policy enforcement, remote wipe capabilities, and device compliance monitoring. Unlike isolated controls like passwords or encryption, MDM allows the organization to enforce security policies dynamically and revoke access or wipe corporate data if a device is lost, stolen, or non-compliant.
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 complex passwords
Why it's wrong here
Passwords are important but alone insufficient for comprehensive security.
- ✗
Install a firewall on each device
Why it's wrong here
Firewalls are useful but not the most important control in BYOD.
- ✗
Enable full disk encryption
Why it's wrong here
Encryption protects data at rest but does not manage devices.
- ✓
Implement mobile device management (MDM) for remote wipe and policy enforcement
Why this is correct
MDM allows IT to enforce security policies and remotely wipe devices if lost or stolen.
