Question

Your organization is planning to issue mobile devices to some employees, but management is concerned about protecting the confidentiality of data if the devices are lost or stolen. What is the BEST way to secure data at rest a mobile device?

Answer 1

The best way to secure data at rest on a mobile device is to use encryption. There are different types of encryption methods that can be used, such as full-disk encryption or file-level encryption. Enabling full-disk encryption on an Android device can help protect all the data on the device.

Step-by-step explanation:

The best way to secure data at rest on a mobile device is to use encryption. Encryption is the process of converting data into a code that can only be accessed with a specific encryption key. By encrypting data on a mobile device, even if the device is lost or stolen, the data will remain secure and cannot be accessed without the encryption key.

There are different types of encryption methods that can be used, such as full-disk encryption or file-level encryption. Full-disk encryption is when the entire storage drive of the mobile device is encrypted, ensuring that all data on the device is protected. File-level encryption, on the other hand, allows for individual files to be encrypted separately.

For example, on an Android device, you can enable full-disk encryption under the device's security settings. This will encrypt all the data on the device and require a passcode or pin to unlock the device and access the data.
