What type of VPN technology creates a secure tunnel over the internet?

The type of VPN technology that creates a secure tunnel over the internet is SSL tunneling. SSL, or Secure Sockets Layer, is a protocol that establishes an encrypted link between a web server and a browser. In the context of a Virtual Private Network (VPN), SSL tunneling allows for secure communication over the public internet, ensuring that the data transmitted remains private and protected from eavesdropping or tampering.

This technology is particularly useful for web-based applications, as it provides a straightforward mechanism for securing connections without requiring additional software on client devices. It operates at the transport layer, creating a secure tunnel that can handle various types of data. The use of SSL adds an extra layer of security by encrypting the data packets transmitted over the internet, making it much more difficult for unauthorized users to access or interpret the information.

Other options, such as dedicated lines, do not create tunnels over the internet but rather provide a direct, private connection that bypasses the public internet. PPTP, while a tunneling protocol itself, is generally considered less secure compared to SSL tunneling. The public internet option does not involve any tunneling or encryption, leaving data vulnerable to interception.
