For you to connect to your Amazon RDS for Db2 DB instance, it must be associated with a security group that contains the necessary IP addresses and network configuration. Your RDS for Db2 DB instance might use the default security group. If you assigned a default nonconfigured security group when you created the RDS for Db2 DB instance, then the firewall prevents internet connections. For information about creating a new security group, see Controlling access with security groups.
After you create the new security group, you modify your DB instance to associate it with the security group. For more information, see Modifying an Amazon RDS DB instance.
You can enhance security by using SSL to encrypt connections to your DB instance. For more information, see Using SSL/TLS with an Amazon RDS for Db2 DB instance.
