RDS for MariaDB DB instances should publish logs to CloudWatch Logs

This control checks whether an Amazon RDS for MariaDB DB instance is configured to publish certain types of logs to Amazon CloudWatch Logs. The control fails if the MariaDB DB instance isn't configured to publish the logs to CloudWatch Logs. You can optionally specify which types of logs a MariaDB DB instance should be configured to publish.

How to fix

Attribute enabled_cloudwatch_logs_exports of aws_db_instance must be non-empty.

Implementation options

Choose the option that matches how you manage Terraform. All options satisfy this control.

Option 1: Open source module (terraform-aws-modules)

If you use terraform-aws-modules/rds/aws, configure the required module inputs to satisfy this control. You can later migrate to the compliance.tf module with minimal changes because it is compatible by design.

module "rds" {
  source  = "terraform-aws-modules/rds/aws"
  version = ">=7.0.0"

  allocated_storage      = 20
  db_name                = "myapp"
  db_subnet_group_name   = "example-db-subnet-group"
  engine                 = "postgres"
  engine_version         = "16.1"
  identifier             = "abc123"
  instance_class         = "db.t3.micro"
  password               = "change-me-in-production"
  username               = "dbadmin"
  vpc_security_group_ids = ["sg-12345678"]
}

Option 2: Terraform AWS provider resources

If you manage resources directly, configure the relevant Terraform AWS provider resources to meet this control. See docs for the resources involved: aws_db_instance.

resource "aws_db_instance" "this" {
  allocated_storage               = 20
  enabled_cloudwatch_logs_exports = ["general", "slowquery"]
  engine                          = "mysql"
  identifier                      = "pofix-example-db"
  instance_class                  = "db.t3.micro"
  monitoring_interval             = 60
  monitoring_role_arn             = "arn:aws:iam::123456789012:role/example-role"
  password                        = "ChangeMe123!"
  skip_final_snapshot             = true
  username                        = "dbadmin"
}
Which option should I choose?
  • Compliance.tf module (recommended): controls enforced by default and mapped to frameworks.
  • Open source module (terraform-aws-modules): compatible by design with compliance.tf. Same variable names for an easy, low-change migration path when you are ready.
  • Terraform AWS provider resources: manage Terraform resources directly.
