# Foxhunt Security Incident Response Plan

## Overview

This document outlines the security incident response procedures for the Foxhunt High-Frequency Trading System. Given the critical nature of financial trading operations, rapid and effective incident response is essential.

## Incident Classification

### Severity Levels

#### Critical (P0)
- **Active trading system compromise**

- **Data breach involving client financial data**
- **Complete system outage during trading hours**
- **Regulatory compliance violation**

#### High (P1)
- **Suspected unauthorized access**
- **Malware detection on trading systems**
- **Abnormal trading patterns**
- **API security breach**
- **Multi-factor authentication bypass**

#### Medium (P2)
- **Failed authentication attempts exceeding thresholds**
- **Suspicious network activity**
- **Configuration drift detection**
- **Certificate expiration warnings**
- **Rate limiting triggers**

#### Low (P3)
- **Information gathering attempts**
- **Non-critical service disruptions**
- **Security scanning activities**
- **Log analysis anomalies**

## Response Team Structure

### Primary Response Team

    # Alert security team
    curl -X POST "$SECURITY_WEBHOOK" -d '{"alert": "Emergency lockdown activated"}'
}

# Gradual restoration
function restore_operations() {
    echo "🔄 RESTORING OPERATIONS"
    
    # Verify system integrity
    /opt/foxhunt/scripts/security-check.sh
    
    # Restore network access
    iptables -P INPUT ACCEPT
    iptables -P FORWARD ACCEPT
    
    # Restart services gradually
