Conceptually, a threat modeling practice flows from a methodology. Numerous threat modeling methodologies are available for implementation. Typically, threat modeling has been implemented using one of five approaches independently: asset-centric, attacker-centric, software-centric, value and stakeholder-centric, and hybrid.
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]
It was initially proposed for threat modeling but was abandoned when it was discovered that the ratings are not very consistent and are subject to debate. It was discontinued at Microsoft by 2008. [2] When a given threat is assessed using DREAD, each category is given a rating from 1 to 10. [3]
Attack trees are conceptual diagrams showing how an asset, or target, might be attacked. [1] Attack trees have been used in a variety of applications. In the field of information technology, they have been used to describe threats on computer systems and possible attacks to realize those threats.
The Swiss cheese model of accident causation is a model used in risk analysis and risk management. It likens human systems to multiple slices of Swiss cheese , which has randomly placed and sized holes in each slice, stacked side by side, in which the risk of a threat becoming a reality is mitigated by the differing layers and types of defenses ...
In this model, analysts and developers freely share applications with one another, choose and modify applications, and accelerate solution development through plug-and-play activities. In addition, threat intelligence can also be acted upon strategically to inform necessary network and security architecture changes and optimize security teams.
For example, the report describes how China-backed groups used Gemini to research U.S. military and U.S.-based IT organizations, U.S. government network ranges, and publicly available information ...
Example of risk assessment: A NASA model showing areas at high risk from impact for the International Space Station. Risk management is the identification, evaluation, and prioritization of risks, [1] followed by the minimization, monitoring, and control of the impact or probability of those risks occurring. [2]
