VPN - Web Protocols
SSL (Secure Socket Layer)
Web based VPN(HTTPS).
Uses Certificate for mutual Auth.
Mostly replaced by TLS.
TLS (Transport Layer Security)
More common for Https.
Certificates.
TLS 1.2
Enhanced Security.
Tighter security / Hashing checks.

L2TP (Layer 2 Tunneling Protocol)
Carries Layer 2 Traffic over Layer 3
No Encryption by itself but Utilizes IPSec

L2TP is there for our transport mechanism and IPSec is our encryption and Authentication measure.

IPSec - IP Security
ESP - (Encapsulating Security Payload)
Encrypts content with Sym Algorithms

AH - (Authentication Header)
Creates checksum & hashes packets

IPcomp - (IP Payload Compression)
Compress IP Payload

IKE - (Internet Key Exchange)
Negotiates shared Secret
