How Can I Prevent Untrusted Source IP Addresses from Accessing RDS for MariaDB?

If you enable public accessibility, your EIP DNS and database port may be vulnerable to hacking. To protect information such as your EIP, DNS, database port, database account, and password, you are advised to set the range of source IP addresses in the RDS security group to ensure that only trusted source IP addresses can access your DB instances.
To prevent your database password from being cracked, set a strong password and periodically change it.
