SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Software projects often lack a systematic security analysis, making it difficult to identify assets, trust boundaries, and potential threats early in development.

Core Features & Use Cases

  • Guides you through understanding the system, enumerating assets, and mapping trust boundaries.
  • Applies a STRIDE-inspired methodology to identify spoofing, tampering, repudiation, information disclosure, denial of service, and elevation of privilege threats.
  • Generates or updates a threat_model.md file containing assets, trust boundaries, STRIDE threats, and required security guarantees.
  • Ideal for new project kickoffs, feature rollouts involving authentication or external integrations, and major architectural revisions.

Quick Start

Run the threat_modeling skill on your repository to produce a comprehensive threat_model.md.

FAQPage Schema
How do I generate a threat model for a software project?▼

Threat modeling identifies assets, trust boundaries, and potential security threats early in development. It applies a STRIDE-inspired methodology to systematically uncover spoofing, tampering, repudiation, information disclosure, denial of service, and elevation of privilege risks.

When do I need to perform threat modeling for architecture changes?▼

You need threat modeling during new project kickoffs, feature rollouts involving authentication or external integrations, and major architectural revisions. This ensures systematic security analysis is applied whenever system boundaries or trust levels change.

How does STRIDE risk analysis work for identifying security threats?▼

STRIDE risk analysis works by categorizing threats into spoofing, tampering, repudiation, information disclosure, denial of service, and elevation of privilege. It guides you through system understanding, asset enumeration, and trust boundary mapping to document required security guarantees.

Can I update an existing threat_model.md file with new security analysis?▼

Threat modeling is ideal for new project kickoffs, feature rollouts involving authentication or external integrations, and major architectural revisions. It provides systematic security analysis when projects lack early identification of assets and trust boundaries.
