# Threat Mitigation Mapping

Connect threats to controls for effective security planning.

## When to Use This Skill

- Prioritizing security investments
- Creating remediation roadmaps
- Validating control coverage
- Designing defense-in-depth
- Security architecture review
- Risk treatment planning

## Core Concepts

### 1. Control Categories

```
Preventive ────► Stop attacks before they occur
   │              (Firewall, Input validation)
   │
Detective ─────► Identify attacks in progress
   │              (IDS, Log monitoring)
   │
Corrective ────► Respond and recover from attacks
                  (Incident response, Backup restore)
```

### 2. Control Layers

| Layer | Examples |
|-------|----------|
| **Network** | Firewall, WAF, DDoS protection |
| **Application** | Input validation, authentication |
| **Data** | Encryption, access controls |
| **Endpoint** | EDR, patch management |
| **Process** | Security training, incident response |

### 3. Defense in Depth

```
                    ┌──────────────────────┐
                    │      Perimeter       │ ← Firewall, WAF
                    │   ┌──────────────┐   │
                    │   │   Network    │   │ ← Segmentation, IDS
                    │   │  ┌────────┐  │   │
                    │   │  │  Host  │  │   │ ← EDR, Hardening
                    │   │  │ ┌────┐ │  │   │
                    │   │  │ │App │ │  │   │ ← Auth, Validation
                    │   │  │ │Data│ │  │   │ ← Encryption
                    │   │  │ └────┘ │  │   │
                    │   │  └────────┘  │   │
                    │   └──────────────┘   │
                    └──────────────────────┘
