Security hardening

OpenStack Compute can be integrated with various third-party technologies to increase security. For more information, see the OpenStack Security Guide.

Encrypt Compute metadata traffic

Enabling SSL encryption

OpenStack supports encrypting Compute metadata traffic with HTTPS. Enable SSL encryption in the metadata_agent.ini file.

  1. Enable the HTTPS protocol.

    nova_metadata_protocol = https

  2. Determine whether insecure SSL connections are accepted for Compute metadata server requests. The default value is False.

    nova_metadata_insecure = False

  3. Specify the path to the client certificate.

    nova_client_cert = PATH_TO_CERT

  4. Specify the path to the private key.

    nova_client_priv_key = PATH_TO_KEY
