Question: How is tunneling accomplished in a vpn?
Tunneling is a technique used in VPNs to create a secure, encrypted connection between two devices over an untrusted network, such as the Internet. Here's how tunneling is accomplished in a VPN:
A VPN client initiates a connection request to a VPN server over the Internet.
The VPN server authenticates the client and establishes an encrypted tunnel between the client and the server.
The client's data is then encapsulated inside a secure, encrypted packet or "tunnel" and sent through the Internet to the VPN server.
The VPN server receives the encrypted packet and decrypts it, revealing the original data.
The server then routes the data to its destination, either through the Internet or a private network.
The process is repeated in reverse for any data sent back from the destination to the client.
The use of tunneling in a VPN provides several benefits, including data confidentiality, integrity, and authenticity. It also allows users to securely access resources on a private network from remote locations without the need for a physical connection.
