SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Threat modeling for code repositories to identify and mitigate security risks before deployment. Anchors every claim to repo evidence and explicit assumptions to avoid generic checklists.

Core Features & Use Cases

  • Evidence-based scope: extracts components, data stores, and entry points from the repo.
  • Threat enumeration: maps assets to trust boundaries and attacker goals.
  • Risk-based mitigations: yields concrete, component-level mitigations tied to the repo.

Quick Start

Provide the repository root path and optional scope to generate a tailored threat model for the project.

FAQPage Schema
How do I generate a threat model for my source code repository?

Threat modeling for a source code repository involves analyzing primary components, data stores, and entry points to document security risks. This skill extracts evidence from the repo to map trust boundaries and list plausible threats with risk ratings.

What is evidence-based threat modeling and how does it avoid generic security checklists?

Evidence-based threat modeling anchors every security claim to repository evidence and explicit assumptions. This approach avoids generic checklists by extracting project-specific components and proposing concrete mitigations tied to actual component boundaries.

Can I perform threat modeling on deployment paths and data stores in my project?

Yes, threat modeling can be applied to deployment paths and data stores within a repository. The process identifies assets, maps trust boundaries, and enumerates attacker goals specific to those deployment paths to yield component-level mitigations.

How do I map trust boundaries and entry points for application security risk assessment?

Mapping trust boundaries and entry points requires enumerating assets and attacker goals across the repository. This risk assessment identifies plausible threats aligned to component boundaries and proposes concrete mitigations for application security.

What is the best way to document plausible threats and mitigations for AppSec?

The best way to document plausible threats for AppSec is to map assets to trust boundaries and assign risk ratings. This yields concrete, component-level mitigations aligned with the repository's specific entry points and data stores.

Does threat modeling work without external dependencies or security tools?

Threat modeling for repositories works without external dependencies by anchoring claims to source-code evidence. It analyzes primary components and deployment paths directly to produce a tailored threat model with risk ratings.
