SERV02_PASSWORD=your_password
# Or use SSH key
SERV02_PRIVATE_KEY_PATH=/path/to/key
```

### 2. Test Connection

```bash
# Basic SSH connection test
npm start

# Scan remote directory
npm run scan /home/brian/Projects

# List files via SFTP
npm run sftp list /home/brian/Projects
```

## 🔐 Security Features

### 🛡️ Security Protection Mechanisms

For comprehensive details on our security architecture, see **[Security Protection Mechanisms](./SECURITY_PROTECTION_MECHANISMS.md)**.

**Quick Summary:**

| Layer | Protection | Score |
|-------|-----------|-------|
| 1. Authentication | MFA + SSH Keys + Strong Passwords | 95/100 ✅ |
| 2. Encryption | AES-256-GCM + PBKDF2 + Key Rotation | 95/100 ✅ |
| 3. Authorization | RBAC (4 roles, least privilege) | 90/100 ✅ |
| 4. Audit Logging | 25+ redaction patterns, compliance | 98/100 ✅ |
| 5. Rate Limiting | Multi-layer (user/IP/global) | 95/100 ✅ |
| 6. Input Validation | Dangerous command filtering | 90/100 ✅ |
| 7. Session Management | Timeout, isolation | 85/100 ✅ |
