• USB Over Network: Devices like the StarTech USB over IP extenders
• Thunderbolt Networking: Direct 10Gbps connection between PCs
• Dedicated IP-KVM: Professional-grade remote management hardware

Security Best Practices

When accessing multiple computers, security should be your top priority. The National Institute of Standards and Technology (NIST) provides comprehensive guidelines for secure remote access:

1. Authentication:
   • Use complex passwords (12+ characters with mixed case, numbers, symbols)
   • Implement two-factor authentication where possible
   • Consider certificate-based authentication for enterprise setups
2. Network Security:
   • Change default RDP port (3389) to reduce automated attacks
   • Use VPN for internet-based access
   • Implement network-level authentication (NLA)
3. System Hardening:
   • Keep both systems fully patched
   • Disable unnecessary services
   • Use host-based firewalls with strict rules
4. Monitoring:
   • Enable logging for all remote access attempts
   • Set up alerts for failed login attempts
   • Regularly review access logs

The NIST Special Publication 800-171 provides detailed requirements for protecting controlled unclassified information in non-federal systems, many of which apply to dual-PC setups handling sensitive data.
