Ensure High-Risk Parameters Cannot Be Arbitrarily Modified via `SET GLOBAL`

中等級 2人工審核tdsql

說明

Users with the SUPER or SYSTEM_VARIABLES_ADMIN privilege can modify system variables online via SET GLOBAL, including security-related parameters (such as sql_mode, read_only).

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。

Run SELECT User, Host FROM mysql.user WHERE Super_priv = 'Y' AND User NOT LIKE 'tdsqlsys%'; and check SYSTEM_VARIABLES_ADMIN grants (SELECT * FROM mysql.global_grants WHERE PRIV = 'SYSTEM_VARIABLES_ADMIN'). Only TDSQL system accounts may hold them; with audit logging enabled, review the audit trail for unexpected SET GLOBAL statements.

修補方式

修補方法: 操作指南或基礎設施修補檔

1. Allow only TDSQL system accounts (tdsqlsys_*) to hold the SUPER privilege. 2. Have business accounts modify parameters uniformly through the OSS management interface. 3. Enable audit logging of SET GLOBAL operations.
