Trusted Automated Exchange of Intelligence Information (TAXII™) is an application layer protocol for the communication of cyber threat information in a simple and scalable manner.
Medallion is a minimal implementation of a TAXII 2.1 Server in Python.
WARNING: medallion was designed as a prototype and reference implementation of TAXII 2.1, and is not intended for production use.
medallion has been designed to be a simple front-end REST server providing
access to the endpoints defined in that specification.
It uses the python framework - Flask <http://flask.pocoo.org/>
_. medallion
depends on back-end "plugins" which handle the persistence of the TAXII data and
metadata. The TAXII specification is agnostic to what type of data a TAXII
server stores, but this will usually be STIX 2 content.
Two back-end plugins are provided with medallion: the Memory back-end and the MongoDB back-end. The Memory back-end persists data "in memory". It is initialized using a json file that contains TAXII data and metadata. It is possible to save the current state of the in memory store, but this back-end is really intended only for testing purposes. The MongoDB backend is somewhat more robust and makes use of a MongoDB server, installed independently. The MongoDB back-end can only be used if the pymongo python package is installed. An error message will result if it is used without that package.
For more information, see the documentation <https://medallion.readthedocs.io/>

Installation
The easiest way to install medallion is with pip
.. code-block:: bash
$ pip install medallion
Usage
As a script
Medallion provides a command-line interface to start the TAXII Server
.. code-block:: text
usage: medallion [-h]
[--host HOST]
[--port PORT]
[--debug-mode]
[--log-level {DEBUG,INFO,WARN,ERROR,CRITICAL}]
CONFIG_PATH
medallion v3.0.0
positional arguments:
CONFIG_PATH The location of the JSON configuration file to use.
optional arguments:
-h, --help show this help message and exit
--host HOST The host to listen on.
--port PORT The port of the web server.
--debug-mode If set, start application in debug mode.
--log-level {DEBUG,INFO,WARN,ERROR,CRITICAL}
The logging output level for medallion.
To run medallion
.. code-block:: bash
$ python medallion/scripts/run.py <config-file>
Make sure medallion is using the same port that your TAXII client will be connecting on. You can specify which port medallion runs on using the --port
option, for example
.. code-block:: bash
$ medallion --port 80 config_file.json
The <config_file> contains:
- configuration information for the backend plugin
- a simple user name/password dictionary
To use the Memory back-end plug, include the following in the :
.. code-block:: json
{
"backend": {
"module_class": "MemoryBackend",
"filename": "<path to json file with initial data>"
}
}
To use the Mongo DB back-end plug, include the following in the :
.. code-block:: json
{
"backend": {
"module_class": "MongoBackend",
"uri": "<Mongo DB server url> # e.g., 'mongodb://localhost:27017/'"
}
}
Note: A Mongo DB should be available at some URL when using the Mongo DB back-end
A description of the Mongo DB structure expected by the mongo db backend code is
described in the documentation <https://medallion.readthedocs.io/en/latest/mongodb_schema.html>
_.
As required by the TAXII specification, medallion supports HTTP Basic authorization. However, the user names and passwords are currently stored in the <config_file> in plain text.
Here is an example:
.. code-block:: json
{
"users": {
"admin": "Password0",
"user1": "Password1",
"user2": "Password2"
}
}
The authorization is enabled using the python package
flask_httpauth <https://flask-httpauth.readthedocs.io>
_.
Authorization could be enhanced by changing the method "decorated" using
@auth.get_password in medallion/init.py
Configs may also contain a "taxii" section as well, as shown below:
.. code-block:: json
{
"taxii": {
"max_page_size": 100
}
}
All TAXII servers require a config, though if any of the sections specified above are missing, they will be filled with default values.
We welcome contributions for other back-end plugins.
Docker
We also provide a Docker image to make it easier to run medallion
.. code-block:: bash
$ docker build . -t medallion
If operating behind a proxy, add the following option (replacing <proxy>
with
your proxy location and port): --build-arg https_proxy=<proxy>
.
Then run the image
.. code-block:: bash
$ docker run --rm -p 5000:5000 -v <directory>:/var/taxii medallion
Replace <directory>
with the full path to the directory containing your
medallion configuration.
