### Description{% #description %}

CloudFront distributions that do not enforce a modern minimum TLS protocol version can allow legacy TLS/SSL versions, increasing the risk of downgrade attacks and interception of data in transit.

For Ansible CloudFront resources (modules `community.aws.cloudfront_distribution` and `cloudfront_distribution`), the `viewer_certificate.minimum_protocol_version` property must be defined and set to `TLSv1.1` or `TLSv1.2` (preferably `TLSv1.2`) when using a custom certificate (`viewer_certificate.cloudfront_default_certificate` set to `false`). Resources that omit `minimum_protocol_version` or specify any other value are flagged.

Secure configuration example for Ansible:

```yaml
- name: Create CloudFront distribution with secure TLS
  community.aws.cloudfront_distribution:
    name: my-distribution
    viewer_certificate:
      cloudfront_default_certificate: false
      acm_certificate_arn: arn:aws:acm:region:acct:certificate/your-cert-id
      minimum_protocol_version: TLSv1.2
```

## Compliant Code Examples{% #compliant-code-examples %}

```yaml
- name: example
  community.aws.cloudfront_distribution:
    state: present
    caller_reference: unique test distribution ID
    origins:
    - id: my test origin-000111
      domain_name: www.example.com
      origin_path: /production
      custom_headers:
      - header_name: MyCustomHeaderName
        header_value: MyCustomHeaderValue
    viewer_certificate:
      cloudfront_default_certificate: true
```

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```yaml
- name: example
  community.aws.cloudfront_distribution:
    state: present
    caller_reference: unique test distribution ID
    origins:
      - id: 'my test origin-000111'
        domain_name: www.example.com
        origin_path: /production
        custom_headers:
          - header_name: MyCustomHeaderName
            header_value: MyCustomHeaderValue
    viewer_certificate:
      cloudfront_default_certificate: false
      minimum_protocol_version: 'SSLv3'
```
