Ensure the TXSQL SQL Firewall Is Enabled
Mô tả
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.).
Cách kiểm tra
Phương pháp kiểm tra: Xem xét thủ công
-- 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).
Cách khắc phục
Phương pháp khắc phục: Hướng dẫn hoặc bản vá hạ tầng
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;
