Risk Analysis: Integration of Multiple Threat Models

Different models target different aspects: There are various threat modeling methodologies, each with its strengths. STRIDE focuses on threats based on data flow, while PASTA looks at attacker motivations. By using complementary models, you get a more well-rounded understanding of potential risks.

Comprehensiveness: No single model covers everything. Combining models helps identify a wider range of threats, including those specific to your organization's context (industry, technology stack)

Deeper understanding: Using multiple perspectives can reveal hidden connections or edge cases you might have missed with a single model. This leads to a more thorough risk assessment.

Here are some things to consider when using multiple threat models:

• Alignment with goals: Choose models that align with your specific security objectives and the system/process under evaluation.

• Resource constraints: Some models are more complex than others. Consider the time and expertise available when selecting models.

• Integration: Look for models that can be integrated effectively to avoid creating silos of information.

Overall, using multiple threat models is a strategic approach to risk assessment, giving organizations a more comprehensive security posture.
