Purpose

Provide a python library that allows for basic creation and editing of OpenIOC objects. It supports a basic CRUD (Create, Read, Update, Delete) for various items:

item	Create	Read	Update	Delete
IOC name	Yes	No	Yes	Yes
IOC description	Yes	No	Yes	Yes
created date	Yes	No	Yes	N/A
last modified date	Yes	No	Yes	N/A
published date	Yes	No	Yes	N/A
link metadata	Yes	No	Yes	Yes
IndicatorItem nodes	Yes	No	NotYet	Yes
Indicator nodes	Yes	No	NotYet	Yes
Parameters	Yes	No	Yes	Yes

Items do not have built in Read operations, since all items can be accesed with built in ElementTree syntax or the use of XPATH to select portions of the IOC.

No decision has been made about whether or not to support changing of existing Indicator/IndicatorItem nodes.

See the Docs located at https://pythonhosted.org/ioc_writer/ and the examples directory for examples of working with the library. The user code should avoid having to call functionality in ioc_writer.ioc_et.

Requirements

The python “lxml” library must be installed. This can be obtained from https://pypi.python.org/pypi/lxml

Installation

See the file named “INSTALL” for instructions on installing this library locally.

Examples

Example code lives in the examples folder of the repository.

1. examples/11_to_10_downgrade Script to downgrade OpenIOC 1.1 to OpenIOC 1.1.

2. examples/openioc_to_yara Scripts that support encapsulating YARA signatures in OpenIOC 1.1 format.

3. examples/simple_ioc_writer Script that consumes a csv of data to build an IOC. this csv contains the content, context, et cetera. An example CSV is provided.
