Final answer:
The best technical control to prevent data losses in case mobile devices are lost or stolen is to use encryption and remote wipe capabilities, supported by a strong mobile device management policy.
Step-by-step explanation:
The best technical control to reduce potential data losses if mobile devices are issued by an organization are lost or stolen is to implement encryption and remote wipe capabilities. Encryption protects the data on the device such that even if the device falls into the wrong hands, the information remains inaccessible without the proper credentials. Remote wipe allows administrators to remotely clear the data from a device if it is reported lost or stolen, thus safeguarding sensitive information.
Additionally, establishing a strong mobile device management (MDM) policy will streamline the process of enforcing encryption, enabling remote wipe, and ensuring that devices remain secure. A comprehensive MDM solution would ensure devices are configured with strong passwords, automatically updated with the latest security patches, and able to be monitored for compliance with organizational security policies.
