+SSL/TLS Authentication & Authorization
+======================================
+
+| PRH does not perform any authorization in AAF, as the only endpoint which is provided by the service is the healthcheck, which is unsecured.
+| For authentication settings there is a possibility to change from default behavior to certificate-based solution independently for DMaaP and AAI communication.
+
+AAI authentication
+^^^^^^^^^^^^^^^^^^
+
+Default
+"""""""
+| By default basic authentication is being used with following credentials:
+| user=AAI
+| password=AAI
+
+Certificate-based
+"""""""""""""""""
+| There is an option to enable certificate-based authentication for PRH towards AAI service calls.
+| To achieve this secure flag needs to be turned on in PRH :ref:`configuration<prh_configuration>` :
+
+.. code-block:: json
+  security.enableAaiCertAuth=true
+
+DMaaP BC authentication
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Default
+"""""""
+| By default basic authentication is being used with following credentials (for both DMaaP consumer and DMaaP publisher endpoints):
+| user=admin
+| password=admin
+
+Certificate-based
+""""""""""""""""""
+| There is an option to enable certificate-based authentication for PRH towards DMaaP Bus Controller service calls.
+| To achieve this secure flag needs to be turned on in PRH :ref:`configuration<prh_configuration>` :
+
+.. code-block:: json
+  --security.enableDmaapCertAuth=true
+
+PRH identity and certificate data
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+| PRH is using ``dcae`` identity when certificate-based authentication is turned on.
+| It's the DCAEGEN2 responsibility to generate certificate for dcae identity and provide it to the collector.
+|
+| PRH by default expects that the volume ``tls-info`` is being mounted under path ``/opt/app/prh/etc/cert``.
+| It's the component/collector responsibility to provide necessary inputs in Cloudify blueprint to get the volume mounted.
+| See :doc:`../../tls_enablement` for detailed information.
+|
+| PRH is using four files from ``tls-info`` DCAE volume (``cert.jks, jks.pass, trust.jks, trust.pass``).
+| Refer :ref:`configuration<prh_configuration>` for proper security attributes settings.
+|
+| **IMPORTANT** Even when certificate-based authentication security features are disabled,
+| still all security settings needs to be provided in configuration to make PRH service start smoothly.
+| Security attributes values are not validated in this case, and can point to non-existent data.
