TF-A Firmware Threat Model
|
|
==========================
|
|
|
|
As the TF-A codebase is highly configurable to allow tailoring it best for each
|
|
platform's needs, providing a holistic threat model covering all of its features
|
|
is not necessarily the best approach. Instead, we provide a collection of
|
|
documents which, together, form the project's threat model. These are
|
|
articulated around a core document, called the :ref:`Generic Threat Model`,
|
|
which focuses on the most common configuration we expect to see. The other
|
|
documents typically focus on specific features not covered in the core document.
|
|
|
|
As the TF-A codebase evolves and new features get added, these threat model
|
|
documents will be updated and extended in parallel to reflect at best the
|
|
current status of the code from a security standpoint.
|
|
|
|
.. note::
|
|
|
|
Although our aim is eventually to provide threat model material for all
|
|
features within the project, we have not reached that point yet. We expect
|
|
to gradually fill these gaps over time.
|
|
|
|
Each of these documents give a description of the target of evaluation using a
|
|
data flow diagram, as well as a list of threats we have identified using the
|
|
`STRIDE threat modeling technique`_ and corresponding mitigations.
