Ensure ALL Events are Audited

高レベル 2自動oceanbase

説明

The database audit function must record all critical operations to support security incident traceability, compliance reviews, and behavioral analysis. 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 audit_trail is not None (DB, DB,EXTENDED, DB_EXTENDED or OS) for the tenant on every server.

チェック方法

監査方法: SQL クエリ

sql_query

out=$(obclient ${OB_CONN:--h127.0.0.1 -P2881 -uroot@sys} -N -B -e "SELECT CASE WHEN COUNT(*) > 0 AND SUM(CASE WHEN UPPER(value) <> 'NONE' THEN 0 ELSE 1 END) = 0 THEN 'compliant' ELSE 'noncompliant' END FROM oceanbase.GV\$OB_PARAMETERS WHERE name = 'audit_trail'" 2>/dev/null) || exit 1; printf '%s\n' "$out"

期待される出力: compliant

修正方法

修正方法: ガイダンスまたは IaC パッチ

ALTER SYSTEM SET audit_trail = 'DB_EXTENDED'; and on 4.2.4+ apply an audit filter: SELECT AUDIT_LOG_FILTER_SET_FILTER('log_all', '{"filter": {"log": true}}'); SELECT AUDIT_LOG_FILTER_SET_USER('%', 'log_all');
