Internetwork traffic privacy
Connections are protected both between Amazon RDS and on-premises applications and between Amazon RDS and other Amazon resources within the same Amazon Region.
Traffic between service and on-premises clients and applications
You have two connectivity options between your private network and Amazon:
An Amazon Site-to-Site VPN connection. For more information, see What is Amazon Site-to-Site VPN?
An Amazon Direct Connect connection. For more information, see What is Amazon Direct Connect?
You get access to Amazon RDS through the network by using Amazon-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 Amazon Security Token Service (Amazon STS) to generate temporary security credentials to sign requests.
