MISP Taxii Server

Build Status Code Health

A set of configuration files to use with EclecticIQ's OpenTAXII implementation, along with a callback for when data is sent to the TAXII Server's inbox.


Manual install

git clone https://github.com/MISP/MISP-Taxii-Server
cd MISP-Taxii-Server

apt-get install libmysqlclient-dev # for mysql_config
pip3 install -r REQUIREMENTS.txt

You'll then need to set up your TAXII database. As you're using MISP, you'll likely already have a MySQL environment running.

mysql -u [database user] -p
# Enter Database password
mysql> create database taxiiauth;
mysql> create database taxiipersist;
mysql> grant all on taxiiauth.* to 'taxii'@'%' identified by 'some_password';
mysql> grant all on taxiipersist.* to 'taxii'@'%' identified by 'some_password';
mysql> exit;

Now configure your TAXII server

cp config/config.default.yaml config/config.yaml

Now, with that data, copy config/config.default.yaml over to config/config.yaml and open it. Edit the db_connection parameters to match your environment. Change auth_api -> parameters -> secret whilst you're here as well.

Do not forget to set your MISP server's URL and API key at the bottom.

If you wish, you can edit the taxii service definitions and collections in config/data-configuration.yaml; full documentation on how this is set up is available at OpenTaxii's docs.

Now it's time to create all your SQL tables. Luckily OpenTaxii comes with commands for this.

You're going to want to export your configuration file to a variable as well.

# An example of this config is in the config directory
export OPENTAXII_CONFIG=/path/to/config.yaml

opentaxii-sync-data config/data-configuration.yaml

OpenTaxii is now ready to roll, we've just gotta do one more thing.

In the repository root directory, run

sudo python3 setup.py install

This will install the TAXII hooks to run when we have new data.

Now we should be ready to go!


This should tell you that there is now a server running on localhost:9000 (maybe a different port if you changed it). If there are no errors, you're good!

If you want to test everything is working, run

taxii-push --path http://localhost:9000/services/inbox -f tests/test.xml \
           --dest my_collection --username admin --password admin

Obviously replace anything that differs in your system.

The client should say "Content Block Pushed Successfully" if all went well.

Now you have a TAXII server hooked up to MISP, you're able to send STIX files to the inbox and have them uploaded directly to MISP. So that's nice <3

There is also an experimental feature to push MISP events to the TAXII server when they're published - that's in scripts/push_published_to_taxii.py. It seems to work, but may occasionally re-upload duplicate events to MISP.

Automated TAXII -> MISP Sync

If you want, there is the ability to synchronise between a remote TAXII server and the local MISP server.

$ install-remote-server.sh

< Add a unique server name here, can be anything >

This will then install 2 files to ~/.misptaxii, one for a local server and one for the remote servers. Edit these files as needed. Run install-remote-server.sh once for each remote server you want to add.

You'll probably want to put the sync script on a crontab,

First, run

echo `which python3` `which run-taxii-poll.py`

to get the path of your script, copy it. Then

crontab -e

This will open your crontab. Paste in

0 */6 * * * <the output of that echo command you just ran>

This will run the polling script every 6 hours to keep things all synced up.


Data truncated for column...

Warning: (1265, "Data truncated for column 'original_message' at row 1")

Warning: (1265, "Data truncated for column 'content' at row 1")

If you encounter the error above, this means you tried to push a STIX file bigger than 65,535 bytes. To fix it run the following commands.

mysql -u [database user] -p
# Enter Database password

mysql> use taxiipersist;
mysql> alter table `inbox_messages` modify `original_message` LONGTEXT;
mysql> alter table `content_blocks` modify `content` LONGTEXT;
mysql> exit;

Specified key was too long

Warning: (1071, 'Specified key was too long; max key length is 767 bytes')

If you encounter the error above, try the following after creating the databases as per this issue:

ALTER DATABASE taxiipersist CHARACTER SET latin1 COLLATE latin1_general_ci;
ALTER DATABASE taxiiauth CHARACTER SET latin1 COLLATE latin1_general_ci;

Nothing appears in MISP

Take note of the user you did export OPENTAXII_CONFIG=/path/to/config.yaml with. If you sudo, this env will be lost. Use sudo -E to preserve env instead.


PyMISP complains about missing certificate verification. Under the misp-options in config.yaml do not simply set verifySSL = False. You can provide the CA bundle, a concatenation of all certificates in the chain, as verifySSL = /path/to/ca_bundle. Alternatively, you can export REQUESTS_CA_BUNDLE=/path/to/ca_bundle.

Verifying the database

To verify that the opentaxii-sync-data worked, check the tables of database taxiipersist:

MariaDB [taxiipersist]> show tables;
| Tables_in_taxiipersist      |
| collection_to_content_block |
| content_blocks              |
| data_collections            |
| inbox_messages              |
| result_sets                 |
| service_to_collection       |
| services                    |
| subscriptions               |

To verify whether the account-creation worked, check database taxiiauth:

MariaDB [taxiiauth]> select * from accounts;
| id | username | password_hash                                                                                 |
|  1 | ltaxii   | pbkdf2:sha256:50000$99999999$1111111111111111111111111111111111111111111111111111111111111111 |

Ambigious Polling Service

In the case that the server you want to poll has multiple POLL services, run

taxii-discovery \
  --host <HOST TO POLL>
  --port <POLLING PORT>
  --discovery <DISCOVERY PATH, sometimes /taxii-discovery-service, may vary>

It'll show you the services available on the server. You'll probably see two POLL services, for different version of TAXII (message binding)

Find the one relevent to you, copy its Service Address, and modify ~/.misptaxii/remote-servers.yml to resemble

- name: "my server"
  taxii_version: "1.1"

now try polling again
