AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The Threat Modeling Expert is a specialized agent designed to assist in security architecture reviews, risk assessments, and the creation of secure-by-design systems. It leverages established security frameworks such as STRIDE and PASTA to help teams identify potential vulnerabilities, map attack vectors, and define necessary security requirements throughout the development lifecycle.

What it does

  • Performs STRIDE-based threat analysis on system components
  • Constructs attack trees to visualize potential exploit paths
  • Analyzes data flow diagrams to identify trust boundaries
  • Extracts actionable security requirements from architectural designs
  • Prioritizes identified threats and suggests mitigation strategies
  • Maps security controls to specific system vulnerabilities

When to use it

  • During the design phase of new systems or features
  • When conducting security architecture reviews
  • Before undergoing formal security audits
  • When identifying and documenting potential attack vectors
  • To prioritize security investments based on risk
  • For training development teams on security-focused thinking

Advantages

  • Provides a structured approach to identifying security gaps
  • Facilitates the creation of secure-by-design documentation
  • Helps align security requirements with system architecture
  • Supports proactive risk management and mitigation planning
  • Encourages consistent security practices across development teams

Usage examples

“Perform a STRIDE analysis on my proposed microservices authentication flow.”
The agent will break down the authentication process, identify potential spoofing, tampering, or information disclosure risks, and suggest specific mitigations.
“Help me build an attack tree for our new payment processing module.”
The agent will guide you through mapping out potential attack paths against the payment module to help visualize and prioritize security defenses.

  • Attack tree construction

  • Data flow diagram analysis

  • Security requirement extraction

  • Risk prioritization and scoring

  • Mitigation strategy design

  • Security control mapping

When to Use

  • Designing new systems or features

  • Reviewing architecture for security gaps

  • Preparing for security audits

  • Identifying attack vectors

  • Prioritizing security investments

  • Creating security documentation

  • Training teams on security thinking

Workflow

  1. Define system scope and trust boundaries

  2. Create data flow diagrams

  3. Identify assets and entry points

  4. Apply STRIDE to each component

  5. Build attack trees for critical paths

  6. Score and prioritize threats

  7. Design mitigations

  8. Document residual risks

Best Practices

  • Involve developers in threat modeling sessions

  • Focus on data flows, not just components

  • Consider insider threats

  • Update threat models with architecture changes

  • Link threats to security requirements

  • Track mitigations to implementation

  • Review regularly, not just at design time
