Detailed explanation-1: -What is a VPN and what does it mean? VPN stands for “virtual private network”-a service that helps you stay private online. A VPN establishes a secure, encrypted connection between your computer and the internet, providing a private tunnel for your data and communications while you use public networks.
Detailed explanation-2: -A VPN uses end-to-end encryption to protect the data being sent from one point to another. This means that the data is encrypted at the source, and decrypted at the destination. A VPN is a great way to keep your data safe from eavesdroppers.
Detailed explanation-3: -IPsec is often used to secure L2TP packets by providing confidentiality, authentication and integrity. The combination of these two protocols is generally known as L2TP/IPsec (discussed below). The two endpoints of an L2TP tunnel are called the L2TP access concentrator (LAC) and the L2TP network server (LNS).
Detailed explanation-4: -Remote Access VPNs–This is the most common type of VPN that is available for users.It uses a secure remote server to connect the users to a private network. A remote-access VPN creates a virtual tunnel between the user’s device and the private network to route the user’s data.
