-  * Default SSL ciphers used by Aurora MySQL have been updated to exclude the less secure DES-CBC3-SHA values from the [SSL_CIPHER](https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_ssl_cipher) database parameter. If you encounter SSL connection issues due to the removal of the DES-CBC3-SHA cipher, please use an applicable secure cipher from the following list, [Configuring cipher suites for connections to Aurora MySQL DB clusters](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraMySQL.Security.html#AuroraMySQL.Security.SSL.ConfiguringCipherSuites).
