Data Markings Concept

Learn more about the Data Markings concept here <https://stixproject.github.io/documentation/concepts/data-markings/>_.

Examples

The following examples demonstrate the intended use of the stixmarx library.

Adding Markings

.. code-block:: python

    # stixmarx imports
    import stixmarx

    # python-stix imports
    from stix.indicator import Indicator
    from stix.data_marking import MarkingSpecification
    from stix.extensions.marking.tlp import TLPMarkingStructure as TLP

    # Create a new stixmarx MarkingContainer with a
    # new STIXPackage object contained within it.
    container = stixmarx.new()

    # Get the associated STIX Package
    package = container.package

    # Create an Indicator object
    indicator = Indicator(title='Indicator Title', description='Gonna Mark This')

    # Add the Indicator object to our STIX Package
    package.add(indicator)

    # Build MarkingSpecification and add TLP MarkingStructure
    red_marking = MarkingSpecification(marking_structures=TLP(color="RED"))
    amber_marking = MarkingSpecification(marking_structures=TLP(color="AMBER"))
    green_marking = MarkingSpecification(marking_structures=TLP(color="GREEN"))

    # Mark the indicator with our TLP RED marking
    # This is the equivalent of a component marking. Applies to all descendants
    # nodes, text and attributes.
    container.add_marking(indicator, red_marking, descendants=True)

    # Mark the indicator with TLP GREEN. If descendants is false, the marking
    # will only apply to the indicator node. Does NOT include text, attributes
    # or descendants.
    container.add_marking(indicator, green_marking)

    # Mark the description text.
    # >>> type(indicator.description.value)  <type 'str'>
    indicator.description.value = container.add_marking(indicator.description.value, amber_marking)
    # >>> type(indicator.description.value)  <class 'stixmarx.api.types.MarkableBytes'>

    # Mark the indicator timestamp attribute.
    # >>> type(indicator.timestamp)  <type 'datetime.datetime'>
    indicator.timestamp = container.add_marking(indicator.timestamp, amber_marking)
    # >>> type(indicator.timestamp)  <type 'stixmarx.api.types.MarkableDateTime'>

    # Print the XML!
    print container.to_xml()

Retrieving Markings

.. code-block:: python

# stixmarx
import stixmarx

# Parse the input into a MarkingContainer
container = stixmarx.parse("stix-document.xml")

# Get container package
package = container.package

# Get the markings that apply to the entire XML document
global_markings = container.get_markings(package)

# Print the dictionary representation for our only global marking
marking = global_markings[0]
print marking.to_dict()

# Get our only indicator from the STIX Package
indicator = package.indicators[0]

# Get the markings from the Indicator.
# Note: This will include the global markings and any other markings
# applied by an ancestor!
indicator_markings = container.get_markings(indicator)

# Print the Indicator markings!
for marking in indicator_markings:
    print marking.to_dict()
