This video explains more about how a VPN works. VPN protocols ensure an appropriate level of security to connected systems when the underlying network infrastructure alone cannot provide it. There are several different protocols used to secure and encrypt users and corporate data. IP security IPsec. Secure Sockets Layer SSL and Transport Layer Security TLS. Point-To-Point Tunneling Protocol PPTP. Layer 2 Tunneling Protocol L2TP. Types of VPNs. Network administrators have several options when it comes to deploying a VPN. Remote access VPN. Remote access VPN clients connect to a VPN gateway server on the organization's' network. The gateway requires the device to authenticate its identity before granting access to internal network resources such as file servers, printers and intranets. This type of VPN usually relies on either IP Security IPsec or Secure Sockets Layer SSL to secure the connection. In contrast, a site-to-site VPN uses a gateway device to connect an entire network in one location to a network in another location. End-node devices in the remote location do not need VPN clients because the gateway handles the connection. Most site-to-site VPNs connecting over the internet use IPsec.

Tunnel endpoints must be authenticated before secure VPN tunnels can be established. User-created remote-access VPNs may use passwords, biometrics, two-factor authentication or other cryptographic methods. Network-to-network tunnels often use passwords or digital certificates. They permanently store the key to allow the tunnel to establish automatically, without intervention from the administrator.
