A small company has recently purchased cell phones for managers to use while working outside if the office.
The company does not currently have a budget for mobile device management and is primarily concerned with deterring leaks if sensitive information obtained by
unauthorized access to unattended phones. Which of the following would provide the solution BEST meets the company’s requirements?

A.
Screen-lock

B.
Disable removable storage

C.
Full device encryption

D.
Remote wiping

Explanation:
Screen-lock is a security feature that requires the user to enter a password after a short period of inactivity before they can access the system again. This feature
ensures that if your device is left unattended or is lost or stolen, it will be difficult for anyone else to access your data or applications.
Incorrect Answers:
B: Merely disabling removable storage will not prevent sensitive information from being accessed by unauthorized people when the phone is left unattended.
C: Device encryption encrypts the data on the device. This feature ensures that the data on the device cannot be accessed in a useable form should the device be
stolen.
D: Remote wipe is the process of deleting data on a device in the event that the device is stolen. This is performed over remote connections such as the mobile
phone service or the internet connection and helps ensure that sensitive data is not accessed by unauthorized people.
