Introduction 

Threat modelling is a process that helps organizations identify potential threats to their systems, applications, or infrastructure. By analysing potential threats and vulnerabilities, organizations can proactively implement countermeasures and improve their security posture. There are several types of threat modelling methodologies, each with its own approach and benefits.  

Most Common Types of Threat Modelling 

  1. STRIDE  
    STRIDE is one of the most widely used threat modelling methodologies. It stands for Spoofing, Tampering, Repudiation, Information disclosure, Denial of Service, and Elevation of Privilege. This model provides a comprehensive framework for analysing potential threats and vulnerabilities across a system. By examining each of these six categories, organizations can identify potential threats and develop effective countermeasures. 

  1. PASTA  
    PASTA (Process for Attack Simulation and Threat Analysis) is a structured threat modelling methodology that focuses on understanding the attacker's perspective. This approach involves analysing potential threats from the attacker's point of view and identifying the most likely attack paths. PASTA can help organizations prioritize their security efforts and focus on the areas that are most vulnerable to attack. 

  1. VAST  
    Visual, Agile, and Simple Threat modelling (VAST) is a newer approach to threat modelling that emphasizes simplicity and agility. VAST involves creating a visual representation of the system being modelled and identifying potential threats through a series of brainstorming sessions. This approach is highly collaborative and can be used to quickly identify potential vulnerabilities and develop countermeasures. 

  1. Trike  
    Trike is a comprehensive threat modelling methodology that incorporates elements of other threat modelling frameworks, including STRIDE and PASTA. This approach involves breaking down the system being modelled into smaller components and analysing each component for potential threats and vulnerabilities. By using a structured approach to threat modelling, organizations can identify potential threats and develop effective countermeasures. 

  1. VECTRA  
    VECTRA (Visual, Empirical, and Comprehensive Threat Risk Assessment) is a newer approach to threat modelling that emphasizes the importance of visual representations and empirical data. This approach involves creating a visual representation of the system being modelled and collecting data on potential threats through real-world testing and analysis. By incorporating empirical data into the threat modelling process, organizations can develop more accurate threat models and improve their security posture. 

Conclusion 

In conclusion, threat modelling is a critical process for identifying potential threats and vulnerabilities in a system. By using one of the above methodologies or a combination of them, organizations can proactively identify potential threats and develop effective countermeasures. It's important to note that threat modelling is not a one-time process but rather an ongoing effort to maintain the security of the system. Regular threat modelling can help organizations stay ahead of emerging threats and keep their systems secure.
