+title: Deception for Defense
+constructs:
+  - Incident
+  - Course of Action
+summary: Leverage deception to build shared awareness of threats
+---
+
+## Scenario
+Network defense teams can leverage deception to mitigate fraud and intrusions, while sharing lessons learned and effective strategies. 
+
+One method of referencing these actions is the "Deception Kill Chain" [described by MITRE ](http://deceptionbook.com)  
+
+An organization might send an Incident report describing their strategy :
+
+- The Purpose of their deception: prevent intruders from unauthorized access to customer accounts 
+- Their Collected Intelligence on intruders
+- Creation of a Cover Story with false identity and associated accounts
+- Their Plan and Preparations to link that identity to the company
+- Monitoring of attempts to interact with the false identity 
+
+## Data model
+To describe deception techniques, an [Incident can reference ](https://stixproject.github.io/data-model/{{site.current_version}}/indicator/IndicatorType/) one or more [Courses of Action that describe mitigation techniques](https://stixproject.github.io/data-model/{{site.current_version}}/coa/CourseOfActionType/)
