Ensure the TXSQL SQL Firewall Is Enabled

中级别 2人工审核tdsql

说明

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.).

检查方式

审计方法: 人工审核

此项建议无法自动检查。当您传入 --include-manual 时，扫描结果会列出该项并附带这些说明。

-- 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).

修复方式

修复方法: 操作指南或基础设施补丁

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;
