The Importance of Threat Modeling

It is a planned method to determine and quantify the potential risks, like vulnerabilities or a lack of defense mechanisms. It also helps to determine the best security measures. Threat modeling aims to provide the security team and security guards with an understanding of the security measures necessary based on present information systems and threat landscape, including the most likely attack as well as their method of attack, motivation and the target system.

The process of modeling threats involves collaboration among Security Architects, Security Operations, Network Defenders, SOC and the team of Threat Intelligence to be aware of each other’s roles in terms of responsibilities, goals, and issues.

The importance of threat modeling

Threat modeling assists threat intelligence analysts to identify how to classify, prioritize, and categorize threats in order to provide effective documentation and reporting that is the main goal of a threat intelligence program. A reliable threat intelligence report assists the security defense as well as the security operations team safeguard IT assets from vulnerabilities and threats.

Threat Modeling Methodologies

When you are implementing a threat modelling approach, it’s equally important to know the distinction between the process, method and the goals. There are a variety of methods of cyber threat modeling that are employed to improve cybersecurity and intelligence methods. To ensure that threat intelligence can be used for action information security professionals as well as cyber threat intelligence experts have to discern which one is aligned with their business’s specific goals and goals.

Here are the most commonly used threat modeling techniques that can be used to identify as well as prioritize risks to IT assets:


The STRIDE approach is a method of threat modeling, which was created by Loren Kohnfelder and Praerit Garg in 1999 in order to find security risks and vulnerabilities to your products.

A mnemonic is used to refer to an assortment of threats: Repudiation, Tampering and Spoofing, Information Disclosure, Denial of Service (DoS), and the Elevation of Privilege.

The stages of the process for attack Simulating and Threat Analyzing (PASTA)

PASTA provides a 7-step approach to develop a method for simulating attacks on IT applications, and analyzing the threat, its source and the dangers they pose to an organisation and ways to minimize their impact. The aim in this method is to pinpoint the threat, count the threat, and then assign an amount. With this approach an organization can identify the most appropriate countermeasures to be implemented to minimize the threat.


TRIKE is an open source threat modeling method that is utilized when performing security audits from a risk-management perspective. The threat modeling of TRIKE is a blend of two models, specifically – Requirement Model and the Implementations Model. The requirement model forms the foundation of TRIKE modeling, which explains the security features that are inherent to any IT system and gives acceptable levels of risk for every asset. The model also facilitates coordination between different security teams and stakeholder groups by creating an understanding of the framework. Following this is an implementation plan. In this model it is an Data Flow Diagram (DFD) is designed to show what happens to data as well as the user’s actions within the system. This model is where risks are evaluated to identify and assign a risk level. In this way, there are security measures or preventive measures are identified to tackle the threat in accordance with the priority and risks assigned.


VAST (Visual Agile, Simplified Threat as well as Simple Threat) method is based on automated threat analysis that encompasses the entire lifecycle of software development across the entire organization, with the adequate integration with instruments and collaboration important stakeholders, including architects, developers security experts, people in the leadership of the company.


The DREAD approach is used to evaluate the risk, analyze and determine the likelihood of risk by grading the threats.


OCTAVE (Operationally Critical Threat and Asset and Vulnerability Evaluation) is a method to assess, identify and manage risk to IT assets. This method identifies the key aspects of security for information and the threats that could compromise their security, confidentiality as well as accessibility. This helps them determine what information is in danger and develop a plan to minimize or eliminate the risk in IT assets.
