Threat Modeling
Identify, communicate, and understand threats and mitigations within your application.
Threat modeling is a structured approach to identifying and addressing potential security threats in your application. By thinking like an attacker, you can proactively identify and mitigate security risks early in the development process.
Explore MethodologiesWhat is Threat Modeling?
Threat modeling is a structured process that helps you:
Identify Threats
Systematically identify potential security threats to your application by thinking like an attacker and considering various attack vectors.
Assess Risks
Evaluate the likelihood and potential impact of each identified threat to prioritize your security efforts.
Implement Mitigations
Develop and implement strategies to mitigate or eliminate identified threats, reducing your application's overall security risk.
Benefits of Threat Modeling
Early Risk Identification
Identify security risks early in the development process, when they are easier and less expensive to fix.
Proactive Security
Take a proactive approach to security by identifying and addressing potential threats before they can be exploited.
Efficient Resource Allocation
Focus your security resources on the most critical threats by prioritizing risks based on likelihood and potential impact.
Improved Security Awareness
Build security awareness across your development team by involving them in the threat modeling process.
Threat Modeling Methodologies
STRIDE
Microsoft's threat modeling methodology that categorizes threats into six types: Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege.
Key Benefits
- Comprehensive coverage of threat types
- Well-established and widely used
- Easy to understand and apply
- Focuses on technical threats
PASTA
Process for Attack Simulation and Threat Analysis is a risk-centric methodology that aligns technical security requirements with business objectives.
Key Benefits
- Risk-based approach
- Aligns security with business objectives
- Comprehensive seven-stage process
- Focuses on attacker motivation
OCTAVE
Operationally Critical Threat, Asset, and Vulnerability Evaluation is a methodology developed by Carnegie Mellon University for identifying and managing information security risks.
Key Benefits
- Focuses on organizational risk
- Self-directed approach
- Flexible and adaptable
- Three-phase process
DREAD
A risk assessment model that quantifies risks based on Damage potential, Reproducibility, Exploitability, Affected users, and Discoverability.
Key Benefits
- Quantitative risk assessment
- Helps prioritize threats
- Simple scoring system
- Focuses on impact

Threat Modeling Best Practices
Start Early
Begin threat modeling during the design phase, before any code is written, to identify and address security issues early.
Involve Cross-Functional Teams
Include developers, security experts, and business stakeholders in the threat modeling process for comprehensive coverage.
Focus on Critical Assets
Identify and prioritize your most valuable assets and focus your threat modeling efforts on protecting them.
Use a Structured Approach
Follow a structured methodology like STRIDE or PASTA to ensure comprehensive coverage of potential threats.
Automate Where Possible
Use threat modeling tools to automate parts of the process and integrate with your CI/CD pipeline.
Review and Update Regularly
Treat threat models as living documents that should be reviewed and updated as your application evolves.
Implementing Threat Modeling in Your Pipeline
Here's a step-by-step guide to implementing threat modeling in your development process:
Define Your System
Create a diagram of your application architecture, identifying components, data flows, trust boundaries, and entry points.
Identify Assets
Identify the valuable assets in your system that need protection, such as sensitive data, critical functionality, or system resources.
Identify Threats
Use a methodology like STRIDE to systematically identify potential threats to your system.
Assess Risks
Evaluate the likelihood and potential impact of each identified threat to prioritize your security efforts.
Develop Mitigations
Identify and implement strategies to mitigate or eliminate the identified threats.
Validate and Iterate
Validate that your mitigations are effective and update your threat model as your application evolves.
