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

Install attack-tree-construction and it becomes one more candidate the router can pick - when it fits.

A listing is a routing target with a manifest: what it does, which domains it covers, what it costs and who publishes it. Once installed it sits beside your own models and tools, is scored like any other candidate for each request, and shows up in the trace when it wins. Ratings come from workspaces that installed it, one per account.
