Threat Model Maturity

Description of session

The session objective was to discuss and answer the questions below.

Question Parameters
1. How do we measure the maturity of a threat model? Data is stored & linkable (higher maturity)
Formalisation (higher maturity)
Process integration
How is the model created? different levels of maturity
Repeatability of the process
Level of TM depth + classification of systems
Re-usable components
Maturity / knowledge / experience of the threat modeler + audience
How much does the TM relate to the actual application (quality degradation over time) / synced versioning
Relation / causation between requirements and the resulting TM
2. How do we measure the maturity of the threat model process? Level 0: ad hoc threat model(s), free form
Level 1: implement a threat model methodology and
- Classification of systems and levels of TM depth
- Accurate documentation that reflects reality
- Ownership is within the security/architecture team?
Level 2: threat model process is integrated in the SDLC / repeatability / formalisation / digitasation + linkability / libraries (e.g., attack) / feedback cycle on threat intel. (e.g., library vulns.)
3. Can maturity frameworks be updated with our measurements? Yes: SAMM
- Talk about the process not the maturity of the TM itself
