EC2 launch templates should use Instance Metadata Service Version 2 (IMDSv2)¶
This control checks whether an Amazon EC2 launch template is configured with Instance Metadata Service Version 2 (IMDSv2). The control fails if HttpTokens is set to optional.
How to fix¶
Attribute metadata_options[0].http_tokens of aws_launch_template must be "required".
Implementation options¶
Choose the option that matches how you manage Terraform. All options satisfy this control.
Option 1: 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_launch_template.
resource "aws_launch_template" "this" {
metadata_options {
http_tokens = "required"
}
}
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.
