+Telemetry support
+-----------------
+
+The Security library has support for displaying Crypto device information
+with respect to its Security capabilities. Telemetry commands that can be used
+are shown below.
+
+#. Get the list of available Crypto devices by ID, that supports Security
features::
+
+ --> /security/list
+ {"/security/list": [0, 1, 2, 3]}
+
+#. Get the security capabilities of a Crypto device::
+
+ --> /security/caps,0
+ {"/security/caps": {"sec_caps": [<array of serialized bytes of
+ capabilities>], "sec_caps_n": <number of capabilities>}}
+
+For more information on how to use the Telemetry interface, see
+the :doc:`../howto/telemetry`.
