Threat Model
Full Title or Meme
A model of an information processing system that shows data flows around the system and which spots in the network that a susceptible to attack.

STRIDE is an acronym for: Spoofing identity, Tampering data, Repudiation (denial of responsibility), Information disclosure (data breach), Denial of Service (a.k.a. DoS), and Elevation of privilege.[4]
Each threat is a violation of a desirable property for a system:
| Threat | Desired property |
|---|---|
| Spoofing | Authenticity |
| Tampering | Integrity |
| Repudiation | Non-repudiability |
| Information disclosure | Confidentiality |
| Denial of Service | Availability |
| Elevation of Privilege | Authorization |

The following Subject matter provides for modeling an application's potential security threats at a logical component level early in the design phase of the application. Specifically, in a computer system, multiple model components are defined to represent respective logical elements ofthe application. Each model component includes a corresponding set of security threats that could potentially be of import not only to the component but also to the application as a whole in its physical implementation. The model components are interconnected to form a logical model of the application. One or more potential security threats are then analyzed in terms of the model components in the
logical model.
