A Python library for parsing and generating CybOX content.
A Python library for parsing, manipulating, and generating Cyber Observable eXpression (CybOX™) v2.1.0 content.
A primary goal of the python-cybox library is to remain faithful to both the CybOX standard and to customary Python practices. There are places where these will conflict, and the goal is to make the library intuitive both to those familiar with the XML schemas (but less familiar with Python) and also to experienced Python developers who want to add CybOX support to their programs.
There are currently two levels of APIs for dealing with CybOX content:
- A low-level API is provided by auto-generated XML Schema - Python class bindings. These bindings were generated using generate_ds. With these, any CybOX content can be parsed from or written to XML, but requires a bit more knowledge of the actual CybOX schemas. These “binding classes” are all located in the cybox.bindings package.
- A higher-level API consisting of manually designed Python classes. These “native classes” are intended to behave more like Python programmers would expect. As they are designed manually, they currently do not support the entire CybOX standard, but rather those object types we expect are used most frequently. These “native classes” also support exporting their content as Python dictionaries and lists, which can easily be converted to JSON. Importing from JSON is also supported.
Releases of the python-cybox library will be given version numbers of the form major.minor.update.revision, where major, minor, and update correspond to the CybOX version being supported. The revision number is used to indicate new versions of the python-cybox library itself.
The cybox package depends on the following Python libraries:
- setuptools (only if installing using setup.py)
For Windows installers of the above libraries, we recommend looking here: http://www.lfd.uci.edu/~gohlke/pythonlibs/.
To build lxml on Ubuntu, you will need the following packages from the Ubuntu package repository:
For more information about installing lxml, see http://lxml.de/installation.html.
The structure of the python-cybox repository is as follows:
- cybox/ : the root package
- examples/ : example scripts that leverage the python-cybox library
- cybox/utils/ : utility modules that are leveraged internally by the python-cybox library
- cybox/test/ : unit tests
- cybox/bindings/ : generateDS created xml-to-python bindings (leveraged in parsing and output of CybOX XML content)
- cybox/core/ : APIs for core CybOX constructs (e.g., Observables)
- cybox/common/ : APIs for common CybOX constructs (e.g., Measure Source)
- cybox/object/ : APIs for CybOX objects (e.g., File Object, Address Object)
Please refer to the example scripts for examples of how to use the python-cybox library.
