To protect data in transit, you must transmit the data using Secure Socket Layer/Transport Layer Security (SSL/TLS) or some form of client-side encryption. SSL/TLS requires you to make use of certificates, which are used to encrypt and decrypt the data.

To protect data at rest, you must create and use encryption keys to encrypt and decrypt your data.
