Amazon RDS Proxy announces TLS 1.3 support for PostgreSQL on Aurora and RDS

[Amazon Relational Database Service (RDS) Proxy](https://aws.amazon.com/rds/proxy/) now supports version 1.3 of the Transport Layer Security (TLS) protocol for Proxy connections to Amazon Aurora PostgreSQL and RDS for PostgreSQL database instances. TLS 1.3 provides improved security through stronger cryptographic algorithms and simplified handshake process as compared to older TLS versions. With this release, RDS Proxy can use TLS 1.3 for connections to Aurora PostgreSQL and RDS for PostgreSQL databases. During connection establishment, Proxy will automatically negotiate the most secure supported TLS version supported with the database. Customers can also configure their PostgreSQL database to require TLS 1.3, by setting the ssl\_min\_protocol\_version parameter in their parameter group. TLS 1.3 is already supported for connections to RDS Proxy, as well as for RDS Proxy connections to MySQL engines. RDS Proxy is a fully managed and a highly available database proxy for RDS and Amazon Aurora databases. RDS Proxy helps improve application scalability, resiliency, and security. For information about TLS version support and related configuration on Aurora, please review [Aurora](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraPostgreSQL.Security.html) documentation.
