A lightweight approach to threat modelling that fits real engineering teams.
A simple flow
- Diagram the system and data flows.
- Ask what can go wrong at each boundary.
- Rank issues by impact and likelihood.
- Track mitigations to closure.
Keep it proportionate
Threat modelling does not need heavyweight tooling. A whiteboard diagram and a tracked list beat an unused formal model.
Link to evidence
Store the model with the design docs so it supports your risk assessment.
This is an educational explainer. For the canonical regulation reference, see the dedicated Security page — or run an assessment to see how it applies to your product.
