An organization has an approved bring your own device (BYOD) policy.

The best way to mitigate the security risk associated with the inappropriate use of enterprise applications on the BYOD devices is to implement BYOD mobile device management (MDM) controls. MDM controls are software tools or services that allow the organization to remotely manage, monitor, and secure the BYOD devices and the enterprise applications and data on them. MDM controls can help to enforce security policies, restrict unauthorized access, encrypt sensitive data, wipe data in case of loss or theft, and update or patch applications. The other options are not as effective as implementing MDM controls, as they are related to the review, awareness, or recovery of the BYOD devices and applications, not the prevention or protection of the security risk. References = Risk and Information Systems Control Study Manual, Chapter 3: IT Risk Response, Section 3.3: IT Risk Response Implementation, page 145.
