Introduction

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

Dependencies

This stix-shifter has the following dependencies:

Your development environment must use Python version: 3.6, 3.7, 3.8 or 3.9

Installation

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-

  1. Main stix-shifter package: pip install stix-shifter

  2. Stix-shifter Utility package: pip install stix-shifter-utils

  3. Desired stix-shifter connector module package: pip install stix-shifter-modules-<module name> Example: pip install stix-shifter-modules-qradar

Usage

As A Command Line Utility

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:

  1. Go to the stix-shifter parent directory
  2. Optionally, you can create a Python 3 virtual environemnt: virtualenv -p python3 virtualenv && source virtualenv/bin/activate
  3. Run setup: python3 setup.py install

Running From the Source

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:

  1. Go to the stix-shifter parent directory
  2. Optionally, you can create a Python 3 virtual environemnt: virtualenv -p python3 virtualenv && source virtualenv/bin/activate
  3. 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

As A Library

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)
