Description

OpenSearch domain endpoints must enforce HTTPS to ensure client connections use TLS and prevent interception or tampering of sensitive data such as queries and credentials. In Ansible tasks using the community.aws.opensearch or opensearch modules, the domain_endpoint_options.enforce_https property must be set to true. Tasks that omit domain_endpoint_options or enforce_https, or that set enforce_https: false, are flagged.

Secure Ansible task example:

- name: create opensearch domain with HTTPS enforced
  community.aws.opensearch:
    domain_name: my-domain
    domain_endpoint_options:
      enforce_https: true
