Amazon RDS for Oracle adds ECC384 CA and ECDSA ciphers
🔒 Amazon RDS for Oracle now supports an ECC384 Certificate Authority and two new ECDSA cipher suites for SSL and OEM Agent options on Oracle Database 19c and 21c. The added cipher suites — TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 and TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384 — offer security comparable to RSA with shorter keys and lower CPU usage. To enable them, select rds-ca-ecc384-g1 as the CA for your DB instances and follow the documented steps to add SSL or modify OEM Agent settings.
