4.5.1. VPN Technologies
VPN Types:
| Type | Connection | Use Case |
|---|---|---|
| Site-to-site | Network-to-network | Branch offices, permanent connections |
| Client-to-site | Device-to-network | Remote workers |
| Clientless | Browser-based | Contractor access without software |
VPN Technologies:
- IPSec: Industry standard, works at Layer 3 (encrypts IP packets)
- SSL/TLS VPN: Works at higher layers, often through web browser
- GRE: Tunneling without encryption (often combined with IPSec)
- WireGuard: Modern, lightweight VPN protocol
Split Tunnel vs. Full Tunnel:
- Full tunnel: All traffic goes through VPN (more secure, higher latency)
- Split tunnel: Only specified traffic uses VPN (better performance, less secure)
