Which three actions are required to secure your data when using FileVault?

To secure your data when using FileVault, enabling FileVault is a crucial action because it activates the encryption process for the entire startup disk. This means that all data on the disk is encrypted, protecting it from unauthorized access, especially if the device is lost or stolen. By encrypting the information with FileVault, you ensure that only users with the correct credentials can access the data, which is fundamental in maintaining confidentiality and integrity.

While there are other best practices for data security, such as backing up data regularly, creating a strong password, and using a firmware password, enabling FileVault specifically provides the encryption needed to secure the data on disk. Without this step, data remains unencrypted and vulnerable to threats. Thus, activating FileVault is essential for initial defense against data breaches and unauthorized access to sensitive information.
