Ensure SQLEngine-to-Data-Node Communication Is Encrypted

高等級 1自動化tdsql

說明

Communication between the TDSQL SQLEngine (proxy layer) and backend data nodes should be encrypted with SSL. Passes when tdsql_conn_datanode_ssl_mode and tdsql_conn_system_ssl_mode are at least REQUIRED (VERIFY_CA recommended). Runs the mysql client against the SQLEngine (compute node) selected by TDSQL_SQLENGINE_OPTS (falls back to TDSQL_MYSQL_OPTS); keep the password in ~/.my.cnf or a login path.

修補方式

修補方法: 操作指南或基礎設施修補檔

Enable three-tier SSL through the OSS SSL centralized-enablement interface: tdsql_enable_ssl = ON, tdsql_conn_datanode_ssl_mode = VERIFY_CA and tdsql_conn_system_ssl_mode = REQUIRED (or stricter).
