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)

2. Node Types

Type Symbol Description
OR Oval Any child achieves goal
AND Rectangle All children required
Leaf Box Atomic attack step

3. Attack Attributes

Attribute Description Values
Cost Resources needed $, $$, $$$
Time Duration to execute Hours, Days, Weeks
Skill Expertise required Low, Medium, High
Detection Likelihood of detection Low, Medium, High

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
