Explanation
IPSec uses IKE (Internet Key Exchange) and ISAKMP (Internet Security Association and Key Management Protocol) to negotiate, establish, and manage Security Associations (SAs) and cryptographic keys between VPN peers. IKE operates in two phases: Phase 1 establishes a secure authenticated channel using ISAKMP, and Phase 2 negotiates the IPSec SAs for data encryption. SSL/TLS uses its own handshake protocol, L2TP relies on IPSec for security but doesn't itself define key exchange, and PPTP uses MPPE for encryption with MS-CHAPv2 for authentication.
