## Summary
hTMM (Hybrid Threat Modeling Method) is a threat modelling method. It is used to identify, enumerate, and prioritize potential threats—such as structural vulnerabilities—from a hypothetical attacker’s point of view.

## Key Facts
- hTMM stands for **Hybrid Threat Modeling Method**.
- hTMM is an **instance of threat modelling**.
- Threat modelling is a **process** used to **identify, enumerate, and prioritize potential threats**, including **structural vulnerabilities**, from an **attacker’s point of view**.
- hTMM is described at: https://insights.sei.cmu.edu/library/a-hybrid-threat-modeling-method/
- The Wikidata description for hTMM is **“Hybrid Threat Modeling Method.”**
- hTMM is related to the broader class **threat modelling**.

## FAQs
### Q: What is hTMM?
A: hTMM is the Hybrid Threat Modeling Method, a threat modelling method. It is used to identify, enumerate, and prioritize potential threats from a hypothetical attacker’s perspective.

### Q: What kind of thing is hTMM classified as?
A: hTMM is classified as **threat modelling**. Threat modelling is a process for finding and prioritizing threats such as structural vulnerabilities.

### Q: Where can I find an official description of hTMM?
A: hTMM is described at the SEI/CMU Insights Library page: https://insights.sei.cmu.edu/library/a-hybrid-threat-modeling-method/. This page is the provided reference URL for the method.

### Q: What does threat modelling (the class hTMM belongs to) do?
A: Threat modelling is a process to identify, enumerate, and prioritize potential threats. It approaches the system from a hypothetical attacker’s point of view and can include structural vulnerabilities.

## Why It Matters
hTMM matters because it sits within the discipline of threat modelling, which is a structured way to reason about security risks before they become incidents. Threat modelling focuses on identifying, enumerating, and prioritizing potential threats—including structural vulnerabilities—by viewing a system the way an attacker might. That attacker-centric perspective helps teams move beyond ad hoc security checks and toward a more systematic understanding of what could go wrong and which issues deserve attention first. As a named method (Hybrid Threat Modeling Method) with a published description, hTMM provides a reference point for practitioners looking for an established approach within the broader threat modelling space. In practice, methods like hTMM support clearer communication about threats, more consistent prioritization, and better alignment between technical findings and security decision-making.

## Notable For
- Being explicitly defined as a **threat modelling** method (an instance of the threat modelling class).
- Having a dedicated published description page: https://insights.sei.cmu.edu/library/a-hybrid-threat-modeling-method/
- Being framed within the attacker-perspective approach characteristic of threat modelling.
- Addressing **potential threats** including **structural vulnerabilities** as part of the threat modelling process.

## Body
### Definition and Naming

### Classification
- **Instance of:** threat modelling.
- Threat modelling is defined as a process in which:
  - potential threats are **identified**
  - threats are **enumerated**
  - threats are **prioritized**
  - analysis is performed from a **hypothetical attacker’s point of view**
  - threats can include **structural vulnerabilities**
