OWASP pytm is a Pythonic framework for threat modeling and the first Threat-Model-as-Code tool: The system is first defined in Python using the elements and properties described in the pytm framework. Based on this definition, pytm can generate a Data Flow Diagram (DFD), a Sequence Diagram and most important of all, threats to the system. [25]
The STRIDE was initially created as part of the process of threat modeling. STRIDE is a model of threats, used to help reason and find threats to a system. It is used in conjunction with a model of the target system that can be constructed in parallel. This includes a full breakdown of processes, data stores, data flows, and trust boundaries. [5]
In particular, "Model driven security (MDS) is the tool supported process of modelling security requirements at a high level of abstraction, and using other information sources available about the system (produced by other stakeholders).
The HRU security model (Harrison, Ruzzo, Ullman model) is an operating system level computer security model which deals with the integrity of access rights in the system. It is an extension of the Graham-Denning model, based around the idea of a finite set of procedures being available to edit the access rights of a subject on an object .
According to the model, the protection state of a computer system can be abstracted as a set of objects , that is the set of entities that needs to be protected (e.g. processes, files, memory pages) and a set of subjects , that consists of all active entities (e.g. users, processes).
Some security experts feel that including the "Discoverability" element as the last D rewards security through obscurity, so some organizations have either moved to a DREAD-D "DREAD minus D" scale (which omits Discoverability) or always assume that Discoverability is at its maximum rating.

A security model may be founded upon a formal model of access rights, a model of computation, a model of distributed computing, or no particular theoretical grounding at all. A computer security model is implemented through a computer security policy. For a more complete list of available articles on specific security models, see Category ...
