Attack Tree Construction

Systematic attack path visualization and analysis.

When to Use This Skill

• Visualizing complex attack scenarios
• Identifying defense gaps and priorities
• Communicating risks to stakeholders
• Planning defensive investments
• Penetration test planning
• Security architecture review

Core Concepts

1. Attack Tree Structure

                    [Root Goal]
                         |
            ┌────────────┴────────────┐
            │                         │
       [Sub-goal 1]              [Sub-goal 2]
       (OR node)                 (AND node)
            │                         │
      ┌─────┴─────┐             ┌─────┴─────┐
      │           │             │           │
   [Attack]   [Attack]      [Attack]   [Attack]
    (leaf)     (leaf)        (leaf)     (leaf)

Best Practices

Do's

• Start with clear goals - Define what attacker wants
• Be exhaustive - Consider all attack vectors
• Attribute attacks - Cost, skill, and detection
• Update regularly - New threats emerge
• Validate with experts - Red team review

Don'ts

• Don't oversimplify - Real attacks are complex
• Don't ignore dependencies - AND nodes matter
• Don't forget insider threats - Not all attackers are external
• Don't skip mitigations - Trees are for defense planning
• Don't make it static - Threat landscape evolves
