Ensure the TXSQL SQL Firewall Is Enabled

中等級 2人工審核tdsql

說明

The TXSQL kernel includes a built-in SQL firewall (txsql_sql_filter) that can reject specific SQL types/keyword patterns or limit the concurrent connections matching a rule. Rule metadata is stored in information_schema.txsql_sql_filter_info (fields: TYPE, ITEM_ID, CURRENT_CONN, MAX_CONN, REJECTED_SQL_COUNT, CREATED_TIME, EXPIRE_TIME, EXPIRED, KEY_STR, ORIGIN_STR, etc.).

檢查方式

稽核方法: 人工審核

此項建議無法自動檢查。當您傳入 --include-manual 時，掃描結果會列出此項目並附帶這些說明。

-- Check the SQL firewall switch SHOW GLOBAL VARIABLES LIKE 'txsql_sql_filter_enable'; -- View configured filter rules and their hit/reject statistics SELECT * FROM information_schema.txsql_sql_filter_info; Confirm txsql_sql_filter_enable = ON, and that interception rules are configured for critical scenarios (financial transaction tables, user data tables).

修補方式

修補方法: 操作指南或基礎設施修補檔

Configuring rules through the OSS management interface is recommended (OSS validates rule legality before pushing). If executing SQL directly as an administrator, the rule syntax of the txsql_sql_filter variable is: -- Enable the SQL firewall SET GLOBAL txsql_sql_filter_enable = ON;
