Ensure the TXSQL SQL Firewall Is Enabled
Descrição
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.).
Como é verificado
Método de auditoria: Revisão manual
-- 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).
Como é corrigido
Método de correção: Orientação ou patch de infraestrutura
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;
