DDoS protection

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 blackhole threshold, blackhole filtering is triggered.

We recommend that RDS instances are accessed over the intranet to avoid DDoS attacks.
