Internetwork traffic privacy

Connections are protected both between Amazon RDS and on-premises applications and between Amazon RDS and other AWS resources within the same AWS Region.

Traffic between service and on-premises clients and applications

You have two connectivity options between your private network and AWS:

• An AWS Site-to-Site VPN connection. For more information, see What is AWS Site-to-Site VPN?

• An AWS Direct Connect connection. For more information, see What is AWS Direct Connect?

You get access to Amazon RDS through the network by using AWS-published API operations. Clients must support the following:

• Transport Layer Security (TLS). We require TLS 1.2 and recommend TLS 1.3.

• Cipher suites with perfect forward secrecy (PFS) such as DHE (Ephemeral Diffie-Hellman) or ECDHE (Elliptic Curve Ephemeral Diffie-Hellman). Most modern systems such as Java 7 and later support these modes.

Additionally, requests must be signed by using an access key ID and a secret access key that is associated with an IAM principal. Or you can use the AWS Security Token Service (AWS STS) to generate temporary security credentials to sign requests.
