Threat Model
-=============
+============
+
+Threat modeling is an important part of Secure Development Lifecycle (SDL)
+that helps us identify potential threats and mitigations affecting a system.
+
+In the next sections, we first give a description of the target of evaluation
+using a data flow diagram. Then we provide a list of threats we have identified
+based on the data flow diagram and potential threat mitigations.
