Limit Accepted Transport Layer Security (TLS) Versions

높음레벨 1자동oceanbase

설명

OceanBase supports multiple protocols of TLS. The higher the version the stronger the security and/or better the performance. Runs obclient with the connection options in OB_CONN (default "-h127.0.0.1 -P2881 -uroot@sys"); point it at the MySQL-mode tenant being assessed and supply the password via OB_CONN (-p...) or a [client] section in ~/.my.cnf. The benchmark rates this recommendation Manual; the automated check covers its objective pass criterion. Passes when sql_protocol_min_tls_version is TLSv1.2 or TLSv1.3 on every OBServer (unset/none, TLSv1 or TLSv1.1 fail).
