EC2 instances should have IAM profile attached

Ensure that an AWS Elastic Compute Cloud (AWS EC2) instance has an Identity and Access Management (IAM) profile attached to it. This rule is non-compliant if no IAM profile is attached to the AWS EC2 instance.

How to fix

Attribute iam_instance_profile of aws_instance must be non-empty.

Implementation options

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

Use the compliance.tf registry module to get this control enforced by default. This control is mapped to the frameworks shown in the tabs above. To begin, see get started with compliance.tf.

module "ec2_instance" {
  source  = "acscessentialeight.compliance.tf/terraform-aws-modules/ec2-instance/aws"
  version = ">=6.0.0"

  instance_type = "t3.nano"
  subnet_id     = "subnet-abc123"
}

module "ec2_instance" {
  source  = "cfrpart11.compliance.tf/terraform-aws-modules/ec2-instance/aws"
  version = ">=6.0.0"

  instance_type = "t3.nano"
  subnet_id     = "subnet-abc123"
}

module "ec2_instance" {
  source  = "cisv80ig1.compliance.tf/terraform-aws-modules/ec2-instance/aws"
  version = ">=6.0.0"

  instance_type = "t3.nano"
  subnet_id     = "subnet-abc123"
}

module "ec2_instance" {
  source  = "ffiec.compliance.tf/terraform-aws-modules/ec2-instance/aws"
  version = ">=6.0.0"

  instance_type = "t3.nano"
  subnet_id     = "subnet-abc123"
}

module "ec2_instance" {
  source  = "hipaa.compliance.tf/terraform-aws-modules/ec2-instance/aws"
  version = ">=6.0.0"

  instance_type = "t3.nano"
  subnet_id     = "subnet-abc123"
}

module "ec2_instance" {
  source  = "nist800171.compliance.tf/terraform-aws-modules/ec2-instance/aws"
  version = ">=6.0.0"

  instance_type = "t3.nano"
  subnet_id     = "subnet-abc123"
}

module "ec2_instance" {
  source  = "nist80053.compliance.tf/terraform-aws-modules/ec2-instance/aws"
  version = ">=6.0.0"

  instance_type = "t3.nano"
  subnet_id     = "subnet-abc123"
}

module "ec2_instance" {
  source  = "nistcsfv11.compliance.tf/terraform-aws-modules/ec2-instance/aws"
  version = ">=6.0.0"

  instance_type = "t3.nano"
  subnet_id     = "subnet-abc123"
}

module "ec2_instance" {
  source  = "pcidss.compliance.tf/terraform-aws-modules/ec2-instance/aws"
  version = ">=6.0.0"

  instance_type = "t3.nano"
  subnet_id     = "subnet-abc123"
}

module "ec2_instance" {
  source  = "rbiitfnbfc.compliance.tf/terraform-aws-modules/ec2-instance/aws"
  version = ">=6.0.0"

  instance_type = "t3.nano"
  subnet_id     = "subnet-abc123"
}

Option 2: Open source module (terraform-aws-modules)

If you use terraform-aws-modules/ec2-instance/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 "ec2_instance" {
  source  = "terraform-aws-modules/ec2-instance/aws"
  version = ">=6.0.0"

  instance_type = "t3.nano"
  subnet_id     = "subnet-abc123"
}

Option 3: 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_instance.

resource "aws_instance" "this" {
  ami                    = "ami-abc12345"
  instance_type          = "t4g.nano"
  subnet_id              = element(["subnet-abc123", "subnet-def456"], 0)
  vpc_security_group_ids = ["sg-abc12345"]

  iam_instance_profile = "example-instance-profile"
}
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.
