Ensure that Microsoft SQL Server and PostgreSQL instances provisioned with Amazon RDS have Transport Encryption feature enabled in order to meet security and compliance requirements. Transport Encryption is the AWS RDS feature that forces all connections to your SQL Server and PostgreSQL database instances to use SSL. Once enabled, the data transport encryption and decryption is handled transparently and does not require any additional action from you or your application.
