When you connect to a VPN, the process of creating an encrypted tunnel between your computer and the VPN server uses a number of security protocols.

Introduction
VPNs, or Virtual Private Networks, are a popular way to keep your data safe and secure when you are online. A VPN encrypts your data before it is sent over the internet, making it much more difficult for hackers and other unauthorized users to access it. There are many different ways to encrypt data, but the most common method is called “tunneling.” Tunneling involves creating a secure “tunnel” between your computer and the VPN server. This tunnel is used to send all of your data back and forth, keeping it safe from prying eyes.
Data Encryption
Data encryption is the most common and effective way to protect transmitted data in a VPN. When data is encrypted, it is turned into a code that can only be decrypted by an authorized user. This ensures that only authorized users can access the data, and that the data cannot be intercepted and read by anyone else.
Data Authentication
Authentication is the process of verifying the identity of a user or devices before granting them access to a system. In a VPN, data authentication is used to protect transmitted data from being accessed by unauthorized users. Data authentication verifies that the data being transmitted has not been altered in any way and that it originated from a trusted source.
Data Compression
When data is transmitted over a VPN, it is compressed to reduce the amount of data that needs to be sent. This can help to speed up the transmission of data and reduce bandwidth usage. Data compression can also help to improve security by making it more difficult for hackers to intercept and tamper with data.
Conclusion
There are two main ways to protect data that is transmitted through a VPN. The first way is through the use of cryptography, which is a process of transforming readable data into an unreadable format. The second way is through the use of tunneling, which is a process of encapsulating data so that it cannot be read or modified by anyone who does not have the proper encryption key.
