VPN Tunneling Concepts

VPN Tunneling Purpose

• The primary purpose is to establish a secure, encrypted connection between two or more networks or devices over a public network, like the internet.

VPN Protocol Encapsulation

• During encapsulation, the VPN protocol packages the original data (payload) within a new "envelope" called a VPN tunnel, adding extra layers of information, like encryption keys and authentication details.
• This encrypts the data and hides its original source and destination, enhancing security and privacy.

Network Support

• VPNs support a wide range of network types, including local area networks (LANs), wide area networks (WANs), and even the internet itself.

Remote Client Benefits

• VPN tunneling allows remote clients (like employees working from home) to access the company's internal network securely and privately, as though they were physically connected within the office.

This quiz covers the concept of VPN tunneling, which involves establishing a logical virtual connection through the internet using VPN protocols to encapsulate and transmit data over the network. It also explores the ability to use public networks for VPN connections.
