 **Security Notes**
 DMAAP code has been formally scanned during build time using NexusIQ and all Critical vulnerabilities have been addressed, items that remain open have been assessed for risk and determined to be false positive. The DMAAP open Critical security vulnerabilities and their risk assessment have been documented as part of the `project <https://wiki.onap.org/pages/viewpage.action?pageId=28379799>`_.

-SSL DmaaP Certificates and Configuration
+Roles and Permissions
+---------------------
+
+| Roles and permissions for DMaaP BC API are configured in connected AAF instance if ``UseAAF`` flag is set.
+| The roles and permissions are being provisioned to AAF instance during DMaaP BC instance initialization phase only when AAF is in use.
+| The default namespace in AAF for storing Bus Controller API roles and permissions is ``org.onap.dmaap-bc.api``.
+| Separate permission is created for every HTTP method on each DMaaP BC REST api endpoint.
+| Refer to :doc:`DMaaP Bus Controller REST API<../../../../dmaap/dbcapi.git/docs/api>` for comprehensive api information.
+| Default name for DMaaP instance in ONAP is ``mr`` which is reflected in instance part of every created permission under DMaaP BC API.
+| Exception of above rule is for ``/dmaap`` endpoint where additionally set of permissions for ``boot`` instance is defined:
+
+.. code-block:: bash
+
+    org.onap.dmaap-bc.api.dmaap|boot|DELETE
+    org.onap.dmaap-bc.api.dmaap|boot|GET
+    org.onap.dmaap-bc.api.dmaap|boot|POST
+    org.onap.dmaap-bc.api.dmaap|boot|PUT
+
+| These permissions are needed during DMaaP initialization phase, until real instance is configured. This set of permissions is also provided in AAF instance by default.
+
+| DMaaP BC api permissions are distributed between several predefined roles:
+
+.. code-block:: bash
+
+    org.onap.dmaap-bc.api.Controller
+    org.onap.dmaap-bc.api.Inventory
+    org.onap.dmaap-bc.api.Metrics
+    org.onap.dmaap-bc.api.Orchestrator
+    org.onap.dmaap-bc.api.PortalUser
+
+**Predefined roles brief description:**
+    - **Controller** - contains all permissions to DMaaP BC REST api, and should be assigned to identities which requires full admin rights to DMaaP BC, like ``dmaap-bc`` service identity itself.
+    - **Inventory** - role defined for functions which require ReadOnly access to the resources provided on DMaaP BC api.
+    - **Metrics** - role designed to be used by external function which examines the counts of topics that were replicating between different MR instances. Main permission of this role is to read from DMaaP BC bridge endpoint.
+    - **Orchestrator** - main role containing all permissions, which client micro-service might need. One of the example functions is ``dmaap plugin`` which is part of DCAE. The difference between this and Controller role is that Orchestrator is not responsible for deploying new k8s cluster or a message-router into that cluster, so it has limited, RO access to dmaap and dcaeLocations endpoints.
+    - **PortalUser** - role designed to be used in DMaaP Bus Controller Web App, which is based on the ONAP Portal SDK. If the UI app is deployed and available in ONAP Portal, portal users which will use DMaaP BC Web App shall be assigned to this role.
+
+Bus Controller API security options
+-----------------------------------
+
+| There are three main properties in ``dmaapbc.properties`` responsible for configuring DMaaP BC API security option.
+| These are ``enableCADI, useAAF, ApiPermission.Class``. Below table describes purpose of each property:

+
+.. note::
+   | When CADI filter is in use it caches internally authorization information for the identities calling BC api by default for 10 minutes.
+   | It can have negative impact on the functions which needs to call the api several times and use newly created permissions in next call.
+   | CADI cache time can be changed by setting ``aaf_user_expires`` property (value in ms) in DMaaP BC ``cadi.properties`` file.
+   | However the lowest achievable cache expiration time is 1 min due to internal CADI framework logic.
