Amazon RDS for Oracle Supports Transport Layer Security (TLS) Version 1.2
Transport Layer Security (TLS) is an industry-standard protocol for securing network connections. You can now use TLS version 1.2 to establish a secure network connection to all editions of Amazon Relational Database Service (RDS) for Oracle.
To enable TLS for your database instance, add the SSL option to an Option Group, and apply the Option Group to your instance. The Oracle SSL option has a new option setting called “SQLNET.SSL_VERSION”, with allowed values of “1.0”, “1.2 or 1.0”, “1.2”. You need to specify a value for new SSL options. All existing SSL options have been backfilled with the value "1.0".
Note that if you currently use any automation to add the Oracle SSL option to an option group, you now need to specify the SQLNET.SSL_VERSION option setting, or your API request will be rejected.
Amazon RDS for Oracle makes it easy to set up, operate, and scale Oracle Database deployments in the cloud. To learn more about using TLS with Amazon RDS for Oracle, please visit the documentation. See RDS Oracle Pricing for regional availability.
