Threat Modeling
Structured threat modeling using STRIDE, data-flow diagrams, and attack trees to identify design-level risks early and guide security decisions before they become costly to fix.
Overview
Threat modeling examines a system's design to find where it could be attacked before those weaknesses are built and deployed. It answers what could go wrong in the architecture, which threats matter most, and what controls should be designed in from the start.
The approach uses STRIDE, data-flow diagrams, and attack trees, and can reference MITRE ATT&CK for realistic adversary behavior. Scope can include a system or feature, its trust boundaries and data flows, and a prioritized set of threats with recommended mitigations for engineering and architecture teams.
Benefits
- Identifies design-level risks early, when they are cheaper and simpler to address.
- Uses STRIDE, data-flow diagrams, and attack trees for structured, repeatable analysis.
- References MITRE ATT&CK so identified threats reflect realistic adversary behavior.
- Gives engineering teams prioritized, actionable mitigations to design in from the start.
Methodology
- 01
System Decomposition
Map the system, its components, trust boundaries, and data flows using data-flow diagrams.
- 02
Threat Identification
Apply STRIDE to identify threats across each element and boundary of the system.
- 03
Attack Analysis
Use attack trees and MITRE ATT&CK to explore realistic paths an adversary might take.
- 04
Risk Prioritization
Rate threats by likelihood and impact to focus attention on what matters most.
- 05
Mitigation Recommendations
Recommend design changes and controls to address the prioritized threats.
- 06
Documentation and Handover
Deliver a threat model document and brief engineering and architecture teams.
