Limit Accepted TLS Versions

ÉlevéeNiveau 2Automatiséeoceanbase

Description

OceanBase supports communication encryption to ensure that traffic between nodes cannot be eavesdropped or tampered with. 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. Passes when sql_protocol_min_tls_version is TLSv1.2 or TLSv1.3 on all OBServer nodes (none, any, TLSv1 or TLSv1.1 fail). Mismatched values across nodes fail because each row is checked.

Méthode de vérification

Méthode d'audit: Requête SQL

sql_query

out=$(obclient ${OB_CONN:--h127.0.0.1 -P2881 -uroot@sys} -N -B -e "SELECT CASE WHEN COUNT(*) > 0 AND SUM(CASE WHEN value IN ('TLSv1.2', 'TLSv1.3') THEN 0 ELSE 1 END) = 0 THEN 'compliant' ELSE 'noncompliant' END FROM oceanbase.GV\$OB_PARAMETERS WHERE name = 'sql_protocol_min_tls_version'" 2>/dev/null) || exit 1; printf '%s\n' "$out"

Sortie attendue: compliant

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure

ALTER SYSTEM SET sql_protocol_min_tls_version = 'TLSv1.2'; (or 'TLSv1.3') and confirm the value on every OBServer with SHOW PARAMETERS LIKE 'sql_protocol_min_tls_version';
