Build comprehensive attack trees to visualize threat paths. Use when mapping attack scenarios, identifying defense gaps, or communicating security risks to stakeholders.

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 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 Templates and detailed worked examples Full template library lives in references/details.md . Read that file when you need concrete templates for this skill. 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
