Threat Modeling
Definition
Threat modeling examines assets to protect, potential attackers, attack paths, and appropriate countermeasures.
A structured process to identify assets, attackers, attack paths, assumptions, and countermeasures of a system.
Simply explained
You systematically consider: What must we protect, who might attack it, by what means, and which measures help against it?
Why it matters in practice
The term contributes to secure, maintainable, and high-performance web applications as well as resilient technical decisions.
Example from business
Before a customer portal extension, a team reviews data flows, trust boundaries, and abuse scenarios.
Limits and pitfalls
- Checklists do not replace system understanding; model, assumptions, and changes must be versioned and reviewed.
Origin & history
Threat modeling evolved from security analysis; methods like STRIDE made it practical in software development.
Use in mid-sized companies
- Possible application: Before a customer portal extension, a team reviews data flows, trust boundaries, and abuse scenarios.
