2. Use VPN access for remote lab management
3. Regular backups of VM snapshots
4. Document configurations and findings
5. Monitor resource usage and performance

Legal and Ethical Guidelines

1. Only test owned systems or explicit permission
2. Respect terms of service for cloud platforms
3. Follow responsible disclosure for findings
4. Maintain confidentiality of sensitive data
5. Use lab knowledge ethically in professional work

Cost Optimization
