How is authentication implemented in a VPN?
What will be an ideal response?
The type of authentication used in a VPN depends on the tunneling protocol. Many networks
use IPsec to authenticate users; VPN participants establish an SA and exchange keys to authenticate one another. PPTP, which is used for dial-up access to a remote server, uses MS-CHAP, in which both computers exchange authentication packets. TLS/SSL uses certificate-based authentication. RADIUS is also commonly used for authentication services in VPN architecture.
VPNs also use digital certificates to authenticate users and encryption to ensure that communications cannot be read even if they are intercepted in transit.
