Ensure Temporary System Account Passwords Are Cleaned Up

中等級 1自動化tdsql

說明

TDSQL creates temporary system accounts during certain management operations (such as privilege migration and DCN synchronization). After the operation completes, temporary accounts should be cleaned up. Runs the mysql client against the TDSQL data node selected by TDSQL_MYSQL_OPTS (e.g. "-h10.0.0.5 -P4001 -utdsql_audit"); keep the password in ~/.my.cnf or a login path rather than MYSQL_PWD or the command line (see 1.4 and 1.5).

檢查方式

稽核方法: SQL 查詢

sql_query

out=$(mysql ${TDSQL_MYSQL_OPTS:-} -NBe "SELECT COUNT(*) FROM mysql.user WHERE User LIKE '%tmp%' OR User LIKE '%temp%'" 2>/dev/null) || exit 1; printf '%s\n' "$out"

預期輸出: 0

修補方式

修補方法: 操作指南或基礎設施修補檔

DROP USER IF EXISTS '<temporary account>'@'<host>'; (e.g. 'tdsqlsys_auth_tmp'@'%') and add periodic temporary-account cleanup to inspections.
