AWS::RDS::DBSecurityGroupIngress

The AWS::RDS::DBSecurityGroupIngress resource enables ingress to a DB security group using one of two forms of authorization. First, you can add EC2 or VPC security groups to the DB security group if the application using the database is running on EC2 or VPC instances. Second, IP ranges are available if the application accessing your database is running on the Internet.

This type supports updates. For more information about updating stacks, see AWS CloudFormation Stacks Updates.

For details about the settings for DB security group ingress, see AuthorizeDBSecurityGroupIngress.

Note

EC2-Classic was retired on August 15, 2022. If you haven't migrated from EC2-Classic to a VPC, we recommend that you migrate as soon as possible. For more information, see Migrate from EC2-Classic to a VPC in the Amazon EC2 User Guide, the blog EC2-Classic Networking is Retiring – Here’s How to Prepare, and Moving a DB instance not in a VPC into a VPC in the Amazon RDS User Guide.
