Ensure Temporary System Account Passwords Are Cleaned Up

MediaNivel 1Automatizadatdsql

Descripción

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).

Cómo se verifica

Método de auditoría: Consulta SQL

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"

Salida esperada: 0

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

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