If the RDS instance is configured to be accessible from the Internet, the instance may suffer from DDoS attacks. If a DDoS attack is detected, the RDS security system enables traffic cleaning first. If traffic cleaning fails or the attack reaches the black hole threshold, black hole filtering is triggered.
|We recommend that RDS instances are accessed over the intranet to avoid DDoS attacks.|
