A company is implementing a new mobile device policy that allows employees to use their personal smartphones to access corporate email and calendar services. However, they must ensure the security of corporate data when communicating over cellular networks. Which of the following is the BEST method to secure these communications?
You selected this option
Implement a VPN for devices accessing corporate resources
You selected this option
Enable full device encryption on all mobile devices
You selected this option
Use biometric authentication to access the corporate email app
You selected this option
Require employees to connect to Wi-Fi with WPA3 encryption when accessing corporate data
Using a VPN ensures that all data transmitted over potentially insecure cellular networks is encrypted and secure, protecting against eavesdropping or interception. While enabling device encryption also secures data on the device, it does not protect the data in transit over cellular networks. Biometric authentication strengthens access control but does not necessarily protect data communications. Lastly, requiring strong WPA3 Wi-Fi passwords is irrelevant to cellular network security, as it pertains to wireless networks, not cellular ones.
