## Overview

Structured approach to detecting, responding to, containing, and recovering from security incidents with comprehensive playbooks and automation.

## When to Use

- Security breach detection
- Data breach response
- Malware infection
- DDoS attacks
- Insider threats
- Compliance violations
- Post-incident analysis

## Quick Start

Minimal working example:

```python
# incident_response.py
from dataclasses import dataclass, field
from typing import List, Dict, Optional
from enum import Enum
from datetime import datetime
import json

class IncidentSeverity(Enum):
    CRITICAL = "critical"  # P1 - Business critical
    HIGH = "high"          # P2 - Major impact
    MEDIUM = "medium"      # P3 - Moderate impact
    LOW = "low"            # P4 - Minor impact

class IncidentStatus(Enum):
    DETECTED = "detected"
    INVESTIGATING = "investigating"
    CONTAINED = "contained"
    ERADICATED = "eradicated"
    RECOVERED = "recovered"
    CLOSED = "closed"

class IncidentType(Enum):
    DATA_BREACH = "data_breach"
    MALWARE = "malware"
    UNAUTHORIZED_ACCESS = "unauthorized_access"
// ... (see reference guides for full implementation)
```
