+# 2. HAL servers (a subset of HwBinder services) contain code with higher
+#    incidence rate of security issues than system/core components and have
+#    access to lower layes of the stack (all the way down to hardware) thus
+#    increasing opportunities for bypassing the Android security model.

+#   the process runs
+# - coredomain_hwservice: are considered safe because they do not pose risks
+#   associated with reason #2 above.
+# - hal_configstore_ISurfaceFlingerConfigs:  becuase it has specifically been
+#   designed for use by any domain.
+# - hal_graphics_allocator_hwservice: because these operations are also offered
