RDS cluster does not have IAM authentication enabled

Description

IAM authentication uses AWS Identity and Access Management (IAM) to authenticate users and applications that connect to your RDS database. This can be more secure than traditional password-based authentication, as it allows you to use IAM policies and multi-factor authentication to control access to your database.

Fix - Buildtime

Terraform

  • Resource: aws_rds_cluster
  • Argument: iam_database_authentication_enabled

```go aws_s3_bucket.test.tf resource "aws_rds_cluster" "enabled" { ... + iam_database_authentication_enabled = true }


## CloudFormation

- **Resource:** AWS::RDS::DBCluster
- **Argument:** Properties.EnableIAMDatabaseAuthentication

```yaml
Resources:
  Enabled:
    Type: 'AWS::RDS::DBCluster'
    Properties:
      ...
+     EnableIAMDatabaseAuthentication: true
