## 🚨 Incident Response Plan

### Phase 1: Detection & Initial Response (0-15 minutes)

#### Automated Detection Triggers
- Unusual transaction patterns
- Failed authentication attempts > threshold
- Unexpected system shutdowns
- Resource consumption anomalies
- Private key access outside normal hours

#### Immediate Actions
1. **Alert Team**: Notify security response team
2. **Stop Operations**: Halt all bot activities immediately
   ```bash
   # Emergency stop command
   pkill -f mev-bot
   systemctl stop mev-bot
   ```
3. **Preserve Evidence**: Capture system state
   ```bash
   # Capture logs
   journalctl -u mev-bot --since="1 hour ago" > incident-logs.txt
   # Capture system state
   ps aux > incident-processes.txt
   netstat -tulpn > incident-network.txt
   ```

### Phase 2: Assessment & Containment (15-60 minutes)

#### Impact Assessment
- **Financial**: Check account balances and recent transactions
- **Operational**: Assess system compromise extent
- **Data**: Verify integrity of critical data
- **Access**: Review authentication logs for breaches

#### Containment Actions
1. **Isolate Systems**: Disconnect compromised systems
2. **Secure Keys**: Move funds to safe addresses if necessary
3. **Change Credentials**: Rotate all authentication credentials
4. **Network Isolation**: Block suspicious network traffic

### Phase 3: Eradication & Recovery (1-24 hours)

#### Root Cause Analysis
- Review audit logs thoroughly
- Analyze attack vectors used
- Identify security gaps exploited
- Document lessons learned

#### System Recovery
1. **Clean Installation**: Rebuild compromised systems
2. **Security Hardening**: Apply additional security measures
3. **Testing**: Verify system integrity before restart
4. **Gradual Restart**: Resume operations incrementally

### Phase 4: Post-Incident (24+ hours)

#### Documentation
- Complete incident report
- Update security procedures
- Share findings with team
- Report to stakeholders

#### Improvement
- Implement preventive measures
- Update monitoring systems
- Enhance detection capabilities
- Schedule security review

## 🔐 Key Management Security

### Private Key Security
- **Storage**: Hardware Security Modules (HSM) or secure enclaves
- **Access**: Multi-factor authentication required
- **Rotation**: Quarterly key rotation schedule
- **Backup**: Secure, encrypted, geographically distributed backups

### Encryption Key Management
```bash
# Generate strong encryption key
openssl rand -base64 32

# Environment variable setup
export MEV_BOT_ENCRYPTION_KEY="your_32_character_minimum_key_here"

# Verify key strength
echo $MEV_BOT_ENCRYPTION_KEY | wc -c  # Should be 32+ characters
```

### Key Rotation Procedure
1. **Generate New Key**: Create new encryption key
2. **Update Configuration**: Deploy new key to all systems
3. **Migrate Data**: Re-encrypt existing data with new key
4. **Verify**: Confirm all systems use new key
5. **Secure Disposal**: Securely delete old key

## 🛡️ Threat Model

### External Threats
- **Malicious Actors**: Attempting to steal funds or disrupt operations
- **Competitor Attacks**: MEV frontrunning or sandwich attacks
- **Network Attacks**: RPC endpoint compromise or manipulation
- **Supply Chain**: Compromised dependencies or infrastructure

### Internal Threats
- **Insider Threats**: Malicious or negligent employees
- **Configuration Errors**: Misconfigured security settings
- **Software Bugs**: Vulnerabilities in custom code
- **Operational Mistakes**: Human errors in procedures

### Mitigation Strategies
- **Defense in Depth**: Multiple security layers
- **Principle of Least Privilege**: Minimal necessary access
- **Continuous Monitoring**: Real-time threat detection
- **Regular Testing**: Ongoing security assessments

---

## 📊 Security Monitoring

### Key Metrics to Monitor
- **Transaction Success Rate**: Sudden drops may indicate attacks
- **Gas Price Anomalies**: Unusual gas prices may signal manipulation
- **Network Latency**: Increased latency may indicate MitM attacks
- **Authentication Failures**: Failed login attempts
- **Resource Usage**: CPU/Memory spikes may indicate DoS attempts

### Alerting Thresholds
```yaml
alerts:
  failed_transactions: >5 in 5 minutes
  authentication_failures: >3 in 1 minute
  gas_price_spike: >200% of normal
  network_latency: >5 seconds
  memory_usage: >90% for 1 minute
```

### Log Analysis
```bash
# Check for suspicious activity
grep "FAILED" logs/mev-bot.log | tail -20
grep "ERROR" logs/mev-bot.log | grep -i "security"
grep "WARN" logs/mev-bot.log | grep -i "auth"

# Monitor transaction patterns
grep "TRANSACTION" logs/mev-bot.log | awk '{print $3}' | sort | uniq -c
```
