**Last Updated**: January 2025  
**Version**: 2.0  
**Classification**: Restricted Access

---

## 📋 Executive Summary

This document provides comprehensive incident response procedures for the Foxhunt HFT trading system, designed to handle security incidents while maintaining system availability and minimizing business impact. All procedures are optimized for ultra-low latency environments where milliseconds matter.

## 🎯 Incident Classification & Response Levels

### Severity Levels

| Level | Impact | Response Time | Escalation |
|-------|--------|---------------|------------|
| **P0 - Critical** | System compromise, trading halt | < 5 minutes | Immediate C-level |
| **P1 - High** | Security breach, data exposure | < 15 minutes | VP Engineering |
| **P2 - Medium** | Attempted breach, policy violation | < 1 hour | Security Manager |
| **P3 - Low** | Security alert, monitoring event | < 4 hours | Security Team |
| **P4 - Info** | Routine security event | Next business day | Automated logging |

### Critical Security Incidents (P0/P1)

- Authentication bypass or privilege escalation
- Unauthorized trading activity
- Data exfiltration or breach
- System compromise or malware detection
- Certificate authority compromise
- Vault security breach
- Production database unauthorized access

## 🚨 Emergency Response Procedures

### Immediate Response (First 5 Minutes)

#### Step 1: Activate Emergency Kill Switch
```bash
# IMMEDIATE: Stop all trading if security breach detected
curl -X POST https://trading-api.internal/emergency/kill-switch \
  -H "Authorization: Bearer $EMERGENCY_TOKEN" \
  -H "X-Emergency-Reason: SECURITY_BREACH"

# Verify trading halt
curl https://trading-api.internal/status/emergency
```

#### Step 2: Isolate Affected Systems
```bash
# Network isolation
sudo iptables -A INPUT -s $COMPROMISED_IP -j DROP
sudo iptables -A OUTPUT -d $COMPROMISED_IP -j DROP

# Service isolation
kubectl scale deployment compromised-service --replicas=0
docker stop $(docker ps -q --filter "name=compromised-service")
```

#### Step 3: Capture Forensic Evidence
```bash
# Memory dump (if possible without disruption)
sudo gcore -o /forensics/memory-dump-$(date +%s).core $PID

# Network traffic capture
sudo tcpdump -i any -w /forensics/network-$(date +%s).pcap &

# Log snapshot
tar -czf /forensics/logs-$(date +%s).tar.gz /var/log/foxhunt/
```

#### Step 4: Notify Incident Commander
```bash
# Automated alert (configured in monitoring)
curl -X POST $PAGERDUTY_WEBHOOK \
  -d '{
    "incident_key": "security-'$(date +%s)'",
    "event_type": "trigger",
    "description": "P0 Security Incident - Trading Systems Affected",
    "client": "Foxhunt HFT",
    "details": {
      "severity": "P0",
      "affected_systems": "trading-service",
      "initial_responder": "'$USER'"
    }
  }'
```

## 🔍 Investigation Framework

### Phase 1: Initial Assessment (0-30 minutes)

#### Evidence Collection
```bash
# System state snapshot
kubectl get pods,services,ingress -A > /forensics/k8s-state-$(date +%s).yaml
docker ps -a > /forensics/docker-state-$(date +%s).txt
systemctl status --all > /forensics/systemd-state-$(date +%s).txt

# User activity analysis
psql -h $DB_HOST -U $DB_USER -d foxhunt_prod -c "
  SELECT 
    timestamp,
    user_id,
    action,
    resource,
    ip_address,
    user_agent
  FROM audit_logs 
  WHERE timestamp > NOW() - INTERVAL '2 hours'
  ORDER BY timestamp DESC
  LIMIT 1000;
" > /forensics/audit-$(date +%s).csv

# Authentication events
grep -r "AUTH_FAILURE\|SUSPICIOUS_LOGIN" /var/log/foxhunt/ | tail -1000 > /forensics/auth-events-$(date +%s).log
```

#### Risk Assessment Matrix
| Factor | Low (1) | Medium (2) | High (3) | Critical (4) |
|--------|---------|------------|----------|--------------|
| **Data Exposure** | Config only | User data | Financial data | Trading positions |
| **System Access** | Read-only | Limited write | Admin access | Root/system |
| **Impact Scope** | Single service | Multiple services | Full system | Multi-tenant |
| **Attack Vector** | Internal | External basic | Advanced persistent | Nation-state |

### Phase 2: Deep Investigation (30 minutes - 2 hours)

#### Timeline Reconstruction
```bash
# Comprehensive log analysis
grep -E "(SECURITY|ERROR|WARN|FAIL)" /var/log/foxhunt/**/*.log | 
  sort -k1,1 > /forensics/security-timeline-$(date +%s).log

# Database forensics
psql -h $DB_HOST -U $DB_USER -d foxhunt_prod -c "
  WITH security_events AS (
    SELECT 
      timestamp,
      event_type,
      user_id,
      details,
      LAG(timestamp) OVER (ORDER BY timestamp) as prev_timestamp
    FROM audit_logs 
    WHERE event_type IN ('LoginFailure', 'PermissionDenied', 'SuspiciousActivity')
      AND timestamp > NOW() - INTERVAL '24 hours'
  )
  SELECT 
    timestamp,
    event_type,
    user_id,
    details,
    EXTRACT(EPOCH FROM (timestamp - prev_timestamp)) as seconds_since_prev
  FROM security_events
  ORDER BY timestamp;
" > /forensics/db-security-timeline-$(date +%s).csv
```

#### Compromise Assessment
```bash
# File integrity check
sudo aide --check > /forensics/integrity-check-$(date +%s).log

# Process analysis
ps aux | grep -E "(unusual|suspicious)" > /forensics/suspicious-processes-$(date +%s).txt
netstat -tulpn | grep LISTEN > /forensics/listening-ports-$(date +%s).txt

# Certificate validation
openssl s390_cert_verify /etc/ssl/certs/foxhunt/*.pem > /forensics/cert-status-$(date +%s).log
```

### Phase 3: Containment & Eradication (2-8 hours)

#### Systematic Containment
```bash
# User account isolation
psql -h $DB_HOST -U $DB_USER -d foxhunt_prod -c "
  UPDATE users 
  SET is_active = false, lockout_until = NOW() + INTERVAL '24 hours'
  WHERE id IN (
    SELECT DISTINCT user_id 
    FROM audit_logs 
    WHERE event_type = 'SuspiciousActivity'
      AND timestamp > NOW() - INTERVAL '2 hours'
  );
"

# API key revocation
psql -h $DB_HOST -U $DB_USER -d foxhunt_prod -c "
  UPDATE api_keys 
  SET is_active = false, revoked_at = NOW()
  WHERE key_id IN (
    SELECT DISTINCT metadata->>'api_key_id'
    FROM audit_logs 
    WHERE event_type = 'AuthenticationFailure'
      AND timestamp > NOW() - INTERVAL '1 hour'
      AND metadata->>'failure_count'::int > 10
  );
"

# Certificate rotation (if compromise detected)
vault write -force pki/root/rotate/internal
vault write -force pki/intermediate/set-signed certificate="$NEW_INTERMEDIATE_CERT"
```

#### Malware/Threat Eradication
```bash
# Container rebuild from known-good images
kubectl rollout restart deployment/trading-service
kubectl rollout restart deployment/backtesting-service
kubectl rollout restart deployment/ml-training-service

# Database cleanup (if needed)
pg_dump foxhunt_prod > /backups/pre-cleanup-$(date +%s).sql
psql -h $DB_HOST -U $DB_USER -d foxhunt_prod -c "
  DELETE FROM audit_logs 
  WHERE event_type = 'MaliciousActivity'
    AND timestamp > NOW() - INTERVAL '1 hour';
"
```

## 🛡️ Recovery Procedures

### System Recovery Checklist

#### Phase 1: Service Restoration
- [ ] Verify all malicious code removed
- [ ] Confirm clean container images deployed  
- [ ] Validate certificate chain integrity
- [ ] Test authentication flows
- [ ] Verify database integrity
- [ ] Confirm network security restored

#### Phase 2: Security Validation
```bash
# Security scan
nmap -sS -O -A trading-api.internal > /forensics/post-recovery-scan-$(date +%s).txt

# Penetration test simulation
python3 /tools/security/quick-pentest.py \
  --target https://trading-api.internal \
  --output /forensics/pentest-$(date +%s).json

# Vulnerability assessment
docker run --rm -v /forensics:/output \
  aquasec/trivy image foxhunt/trading-service:latest \
  --format json --output /output/vuln-scan-$(date +%s).json
```

#### Phase 3: Trading System Restart
```bash
# Gradual system restart
echo "Restarting Foxhunt HFT System - $(date)"

# 1. Database and vault
kubectl scale deployment vault --replicas=1
kubectl scale deployment postgresql --replicas=1
sleep 30

# 2. Core services
kubectl scale deployment trading-service --replicas=1
sleep 60

# 3. Support services  
kubectl scale deployment backtesting-service --replicas=1
kubectl scale deployment ml-training-service --replicas=1
sleep 30

# 4. Validate trading readiness
curl -f https://trading-api.internal/health/ready || exit 1
curl -f https://trading-api.internal/health/trading-ready || exit 1

# 5. Remove emergency kill switch
curl -X DELETE https://trading-api.internal/emergency/kill-switch \
  -H "Authorization: Bearer $EMERGENCY_TOKEN"

echo "System recovery completed at $(date)"
```
