Ensure Temporary System Account Passwords Are Cleaned Up

中级别 1自动化tdsql

说明

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).

检查方式

审计方法: SQL 查询

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"

预期输出: 0

修复方式

修复方法: 操作指南或基础设施补丁

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