+Security Handling
+=================
+
+Security Disclosures
+--------------------
+
+We disclose all security vulnerabilities we find, or are advised about, that are
+relevant to Trusted Firmware-A. We encourage responsible disclosure of
+vulnerabilities and inform users as best we can about all possible issues.
+
+We disclose TF-A vulnerabilities as Security Advisories, all of which are listed
+at the bottom of this page. Any new ones will, additionally, be announced as
+issues in the project's `issue tracker`_ with the ``security-advisory`` tag. You
+can receive notification emails for these by watching the "Trusted Firmware-A"
+project at https://developer.trustedfirmware.org/.
+
+Found a Security Issue?
+-----------------------
+
+Although we try to keep TF-A secure, we can only do so with the help of the
+community of developers and security researchers.
+
+.. warning::
+   If you think you have found a security vulnerability, please **do not**
+   report it in the `issue tracker`_ or on the `mailing list`_. Instead, please
+   follow the `TrustedFirmware.org security incident process`_.
+
+One of the goals of this process is to ensure providers of products that use
+TF-A have a chance to consider the implications of the vulnerability and its
+remedy before it is made public. As such, please follow the disclosure plan
+outlined in the process. We do our best to respond and fix any issues quickly.
+
+Afterwards, we encourage you to write-up your findings about the TF-A source
+code.
+
+Attribution
+-----------
+
+We will name and thank you in the :ref:`Change Log & Release Notes` distributed
+with the source code and in any published security advisory.
