Ensure Connection-Control Failed-Login Delay Is Enabled

MediaNivel 1Automatizadatdsql

Descripción

TDSQL MySQL instances integrate the upstream connection_control plugin (SQLEngine/plugin/connection_control/connection_control.cc), which imposes an increasing delay on a client connection after consecutive failed logins, mitigating brute-force attacks. 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). Passes when the CONNECTION_CONTROL plugin is ACTIVE and connection_control_failed_connections_threshold is greater than 0; review the min/max connection delays against policy.
