How does a virtual private network (VPN) provide secure remote access?

A virtual private network (VPN) establishes secure connections for remote users by creating a private network over a public network like the internet. This is achieved through a process called tunneling, where data is encrypted before being transmitted through the public network. The VPN client on the user’s device encrypts the data, which is then sent to the VPN server through a secure connection. The VPN server decrypts the data and forwards it to the intended destination, allowing remote users to access resources securely as if they were directly connected to the private network.
