STIX-shifter is an open source python library allowing software to connect to products that house data repositories by using STIX Patterning, and return results as STIX Observations.
For more information about this project, see the STIX-shifter Overview
This stix-shifter has the following dependencies:
- stix2-patterns==1.3.0
- stix2-validator==1.1.2
- stix2-matcher==1.0.0
- antlr4-python3-runtime==4.8
- python-dateutil==2.8.1
Your development environment must use Python version: 3.8 greater
The recommended method for installing the STIX-shifter is via pip. Two prerequisite packages needs to be installed inlcuding the package of stix-shifter connector module to complete a stix-shifter connector installation. Run below commands to install all the packages-
-
Main stix-shifter package:
pip install stix-shifter -
Stix-shifter Utility package:
pip install stix-shifter-utils -
Desired stix-shifter connector module package:
pip install stix-shifter-modules-<module name>Example:pip install stix-shifter-modules-qradar
The STIX-Shifter comes with a bundled script which you can use to translate STIX Pattern to a native datasource query. It can also be used to translate a JSON data source query result to a STIX bundle of observable objects. You can also send query to a datasource by using a transmission option.
More details of the command line option can be found here
$ stix-shifter translate <MODULE NAME> query "<STIX IDENTITY OBJECT>" "<STIX PATTERN>" "<OPTIONS>"
Example:
$ stix-shifter translate qradar query {} "[ipv4-addr:value = '127.0.0.1']" {}
In order to build stix-shifter packages from source follow the below prerequisite steps:
- Go to the stix-shifter parent directory
- Optionally, you can create a Python 3 virtual environemnt:
virtualenv -p python3 virtualenv && source virtualenv/bin/activate - Run setup:
python3 setup.py install
You may also use python3 main.py script. All the options are the same as "As a command line utility" usage above.
Example:
python3 main.py translate qradar query {} "[ipv4-addr:value = '127.0.0.1']" {}
In order to run python3 main.py from the source follow the below prerequisite steps:
- Go to the stix-shifter parent directory
- Optionally, you can create a Python 3 virtual environemnt:
virtualenv -p python3 virtualenv && source virtualenv/bin/activate - Run setup to install dependancies:
INSTALL_REQUIREMENTS_ONLY=1 python3 setup.py install.
Note: setup.py only installs dependencies when INSTALL_REQUIREMENTS_ONLY=1 directive is used. This option is similar to python3 generate_requirements.py && pip install -r requirements.txt
You can also use this library to integrate STIX Shifter into your own tools. You can translate a STIX Pattern:
from stix_shifter.stix_translation import stix_translation
translation = stix_translation.StixTranslation()
response = translation.translate('<MODULE NAME>', 'query', '{}', '<STIX PATTERN>', '<OPTIONS>')
print(response)
If a connector has been installed using pip, the process for editing the STIX mappings is different than if you have pulled-down the project. When working locally, you can edit the mapping files directly. See the mapping files for the MySQL connector as an example. Editing the mapping files won't work if the connector has been installed with pip; the setup script of the stix-shifter package includes the mapppings inside config.json. This allows stix-shifter to injest custom mappings as part of the connector's configuration.
Refer to Use of custom mappings for more details on how to edit the mappings in the configuration.
