Threat Modeling Guide for Web Applications
Web applications are a prime target for security threats. A solid **threat modeling** process helps identify vulnerabilities early, ensuring your app remains secure. This guide follows industry best practices.
---
Understand the Application Architecture
Before modeling threats, map out the web application’s architecture: - Identify **entry points** (e.g., login pages, APIs). - Define **trust boundaries** (e.g., database vs. front-end). - Document **components** (e.g., authentication systems, third-party integrations).
Tools
- Diagrams.net (formerly draw.io) - OWASP Threat Dragon - Microsoft Threat Modeling Tool
---
Identify Potential Threats Using STRIDE
Use the **STRIDE** framework to categorize risks:
| **Description** | **Example** | | |||||
| Impersonating an entity | Stolen credentials used to access admin portal | | Modifying data | Injection attacks manipulating database entries | | Denying actions | Lack of logging allows attackers to erase footprints | | Exposing sensitive info | Leaked API keys or SQL errors revealing database schema | | Disrupting service | DDoS attacks flooding the application | | Gaining higher access | Bypassing access controls to become an admin | |
- Recommended Approach:**
- **Map attack vectors** for each STRIDE category. - **Assess impact** of each threat scenario.
Tools
- OWASP ZAP - Burp Suite - Mitre ATT&CK framework
Define Mitigation Strategies
To defend against threats: - **Authentication security:** Use **OAuth 2.1** or **FIDO2** for identity management. - **Input validation:** Implement **strict sanitization** to prevent SQL Injection & XSS. - **Encryption & Secure Storage:** Protect data at rest with AES-256 and in transit using TLS 1.3. - **Logging & Monitoring:** Use **SIEM tools** (Splunk, ELK) to detect suspicious behavior. - **Rate Limiting & Firewalls:** Deploy **WAF** (Cloudflare, AWS Shield) to prevent DDoS.
Tools
- OWASP Dependency Check - SIEM (Splunk, Elastic Security) - Web Application Firewalls (ModSecurity, AWS WAF)
---
Validate & Iterate the Model
Threat modeling is **not a one-time process**—it should evolve as the application grows. - Conduct **regular security audits.** - Perform **penetration testing** (ethical hacking). - Update **threat models** when infrastructure changes occur.
Recommended Practices
- Integrate threat modeling into **DevSecOps workflows**.
- Use **CI/CD pipelines** for automated security checks.
- Encourage **security awareness** among developers.
