What technology creates a secure tunnel across untrusted networks to prevent eavesdropping?

A Virtual Private Network (VPN) creates a secure tunnel across untrusted networks, such as the internet, facilitating secure communication and data transmission. It achieves this through encryption, ensuring that any data sent or received is protected from eavesdropping or interception by unauthorized parties. When users connect to a VPN, their device is assigned a secure IP address, and their internet traffic is routed through the VPN server, which acts as an intermediary between the user and the public internet. This not only masks the user's IP address but also secures the data through encryption protocols, making it difficult for anyone to decipher.

The other options do not fulfill the same role. A Dedicated Private Network is typically used to create a private link that does not traverse the public internet, providing security without the need for tunneling. Secure Socket Layer (SSL) is primarily used for securing communication between a web browser and a server, but it does not create a tunnel in the same way a VPN does. Network Address Translation (NAT) is a technology used to map private IP addresses to a public IP address, which can help in securing a network by hiding the internal structure from the outside world but does not create a secure tunnel. Therefore, VPN remains the most suitable choice for establishing
