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.

Context

Carnegie Mellon University Software Engineering Institute published a report on "Threat Modeling: 12 Available Methods" [1]

Loren Kohnfleder paper 'Threat Modeling Retrospective'[2]

Crispin Cowan on The Calculus of Threat Modeling [3]

Problems

Solutions

A comprehensive Data Flow Diagram

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 of

the 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.
