VPN gateways must authenticate to each other prior to exchanging information. What are the two types of credentials used for authentication?
VPN gateways commonly authenticate to each other using Certificates and pre-shared secrets before exchanging information. Certificates provide a mutually trusted framework for verification, while pre-shared secrets offer a simpler, shared key method for authentication. This ensures both parties are reliably identified before any data transfer occurs.
from CCSA R80 guide: Before the VPN gateways can create VPN tunnels, they first need to authenticate to each other. Authentication is how the VPN gateways are completely certain that they can trust the other networks and share data. VPN gateways authenticate to each other by presenting one of the following types of credentials: • Certificates • Pre-shared secret
VPN gateways authenticate using Digital Certificates and Pre-shared secrets. Reference: https://sc1.checkpoint.com/documents/R77/CP_R77_VPN_AdminGuide/85469.htm
