Setting a Security Group¶
Scenarios¶
This section explains how to add a security group rule to control access to and from the DDS DB instances associated with a security group.
Precautions¶
The default security group rule allows all outgoing data packets. ECSs and DDS DB instances in the same security group can access each other. After a security group is created, you can create different rules for that security group, which allows you to control access to the DB instances that are in it.
To access a DB instance in a security group from a source outside of that group, you need to create an inbound rule.
For details about the constraints on using security groups, see "Security Group Overview" in the Virtual Private Cloud User Guide.
