• Post-incident analysis

Quick Start

Minimal working example:

# 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"
