Securing connections to RDS for PostgreSQL with SSL/TLS

RDS for PostgreSQL supports Secure Socket Layer (SSL) encryption for PostgreSQL DB instances. Using SSL, you can encrypt a PostgreSQL connection between your applications and your PostgreSQL DB instances. You can also force all connections to your PostgreSQL DB instance to use SSL. RDS for PostgreSQL also supports Transport Layer Security (TLS), the successor protocol to SSL.
