US Patent 8732838 Evaluating the effectiveness of a threat model

Evaluating a threat model for structural validity and descriptive completeness. A threat modeling application provides a progress factor or other overall score associated with the structural validity and descriptive completeness of the threat model being evaluated. The structural validity is evaluated based on a data flow diagram associated with the threat model. The descriptive completeness is evaluated by reviewing descriptions of threat types in the threat model. The progress factor encourages modelers to provide effective models to a model reviewer, thus saving time for the model reviewer.
