Create a TAXII outgoing feed#

To exchange data between two platform instances configure:

  • A TAXII inbox or a TAXII poll feed (outgoing -> incoming).

  • A TAXII data feed collection both platform instances can access to:

    • Make data available (Alice, the publishing platform instance).

    • Retrieve data (Barbara, the recipient platform instance).

  • An EclecticIQ JSON content type for both the outgoing and the incoming feeds.

In the publishing platform instance (Alice) configure either a TAXII inbox outgoing feed, or a TAXII poll outgoing feed.

Note

About transport

  • Both platform instances must exchange data through the same TAXII transport protocol service: either TAXII inbox or TAXII poll.

About content

  • Although TAXII feed configurations make available more than one content type for the incoming and the outgoing feeds, platform to platform data exchange officially supports only EclecticIQ JSON as a valid data exchange content type.

  • Regardless of Alice’s outgoing and Barbara’s incoming feeds using either the TAXII inbox or the TAXII poll transport types, they both need to publish data to and retrieve data from the same TAXII collection:

    • Alice (publisher) should publish content through a TAXII outgoing feed and a specified Collection name – for a TAXII poll transport type – or a Destination collection name – for a TAXII inbox transport type.

    • Barbara (recipient) should ingest content through a TAXII incoming feed, and it should ingest from or poll the same Collection name specified under Collection name or Destination collection name in Alice’s TAXII outgoing feed configuration.

About user access control and permissions

  • Set the automation user and, where applicable, group you created as the user and the authorized group that are granted access to the feed.

  • Specify the automation user’s user name and password in the corresponding feed configuration fields.

  • If you enable basic authentication, make sure the automation role has the required additional permissions.

Create a TAXII inbox outgoing feed#

Set up and configure transport and content types for TAXII inbox outgoing feeds to publish selected platform data through the TAXII inbox service.

To configure the general options for TAXII inbox outgoing feeds, see Configure the general options and the other relevant child articles under Outgoing feeds.

Note

Assign unique names to TAXII feeds: TAXII inbox and TAXII poll incoming and outgoing feeds in the platform should all have unique names.

Configure the transport type#

Note

Before configuring a TAXII transport type for an incoming or an outgoing feed, make sure that the appropriate TAXII service is correctly configured in the platform_settings.py.

TAXII inbox and TAXII poll transport types require Cabby.

For more information, see official Cabby documentation, the Cabby public repo on GitHub, and the Cabby download page.

The TAXII inbox transport type for outgoing feeds publishes data in the supported content types through the TAXII inbox service:

  1. From the Transport type drop-down menu, select TAXII inbox.

    Under Transport configuration, set the following transport options for the feed:

    • Auto Discovery: enter the URL pointing to a TAXII discovery service.

      Feed consumers can send a request to the discovery service to obtain a list of the available TAXII services they can access and poll for content updates.

      Example: http://hailataxii.com/taxii-discovery-service

    • Inbox service URL: enter the URL pointing to the location of the TAXII data collections available through the TAXII inbox service.

      Example: https://example.com/taxii-inbox

    • Destination collection name: enter an existing collection name as the target container for the outgoing feed data.

      Example: collection.Default

    • TAXII version: select the TAXII version your system supports:

    • EclecticIQ authentication URL: enter the URL pointing to the EclecticIQ Platform instance, including the endpoint that takes the user name and password inputs to send them to the authentication mechanism.

      Example: https://${platform_host_name}/api/auth

    • Basic authentication: if the data source TAXII server requires basic authentication to access the corresponding TAXII services, select this checkbox to fill out the required information.

      • Username: enter a valid user name to authenticate and be granted the necessary authorization to access the location of the outgoing feed content.

      • Password: enter a valid password to authenticate and be granted the necessary authorization to access the location of the outgoing feed content.

    • SSL certificate authentication: if the TAXII server requires an SSL certificate to authenticate and to authorize access to the corresponding TAXII services, select this checkbox to fill out the required information.

      • SSL certificate: copy-paste the content of a valid SSL certificate to authenticate.

        SSL certificate file format: .pem

        Example:

Create a TAXII poll outgoing feed#

To configure the general options for TAXII inbox outgoing feeds, see Configure the general options and the other relevant child articles under Outgoing feeds.

Note

Assign unique names to TAXII feeds: TAXII inbox and TAXII poll incoming and outgoing feeds in the platform should all have unique names.

Configure the transport type#

Note

Before configuring a TAXII transport type for an incoming or an outgoing feed, make sure that the appropriate TAXII service is correctly configured in the platform_settings.py.

TAXII inbox and TAXII poll transport types require Cabby.

For more information, see official Cabby documentation, the Cabby public repo on GitHub, and the Cabby download page.

The TAXII poll transport type for outgoing feeds publishes data in the supported content types through the TAXII poll service:

  1. Create an outgoing feed.

  2. From the Transport type drop-down menu, select TAXII poll.

  3. Select the Public checkbox to make the outgoing feed available to all platform groups and to all platform users.

    Leave it deselected to make the outgoing feed available only to specific groups.

    You can select the intended recipient groups in Authorized groups.

    Default value: deselected

  4. From the Authorized groups drop-down menu, select one or more groups to grant them access to the feed.

    This option restricts access to the outgoing feed only to the selected user groups and to their members.

    Authorized groups is only available when Public is deselected (default setting).

  5. In the Collection name field, enter the name of the TAXII data collection you want to use to consolidate the outgoing feed content.

    The data collection name can be max. 1024 characters long, and its XML schema should comply with the xsd:anyURI data type.

    Example: MalwareDomainList_Hostlist

Configure the content type#

  1. From the Content type drop-down menu, select EclecticIQ JSON as the appropriate content type for the data you want to exchange between the two platform instances.

    The selected content type needs to match the actual format of the source/input data.

  2. From the Datasets drop-down menu, select one or more existing datasets to use as sources to populate the outgoing feed content.

    For the feed not to be empty, at least one selected dataset should contain entities and observables in the same format as the configured content type for the feed.

  3. From the Update strategy drop-down menu, select the preferred method to populate the outgoing feed with data before publishing it:

    Note

    For more information about update strategies, see Create and configure outgoing feeds

The EclecticIQ JSON content type is suitable for machine consumption.

For example, you can use EclecticIQ JSON as a content type in a IC-to-IC data exchange setup.

Under Content configuration, set the EclecticIQ JSON content type option:

  1. Select the Override producer checkbox to replace the value defining the identity of the original producer of the data with the producer name defined for the platform.

    To find this value, select Settings Settings > STIX and TAXII > STIX > Add STIX settings >Producer.

    Leave it deselected to include the identity of the original producer of the information.

    This setting affects the data.producer.identity.name value in the entity JSON entity data structure:

    {
  "data": {
    "producer": {
      "type": "information-source",
      "identity": {
        "type": "identity"
        "name": "${producer_identity}", // ex.:'EclecticIQ'

      }
    }
  }
}
