## 🚨 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
|
|

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

## 🔐 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
|
