What is a VPN tunnel? – clear cut information of the protocols.

Everyone is on the move to the virtual private network because of the high access to security and privacy. This article will help you with what is VPN tunnel, the protocols used for tunneling, the configuration, and so on.

What is VPN tunnel?

A VPN tunnel is the connection between your device and the wider internet and is encrypted for the sake to avoid tracking, shoplifting your data, interception, etc., It not only hides your browsing information but also masks your IP address to the Websites. It also benefits users with anonymity. The encrypted tunnels are constructed using protocols.

The additional benefit of using a VPN is no one can trace your location which can be possible by masking your IP address. So, when they access your location, they tend to get the address of the VPN server which you are connected to and not your originals.

So you need not worry about internet searches, transactions, or even chats.

Types of VPN

There are specifically three types, based on the requirements

  • Remote access
  • Intranet-based site-to-site
  • Extranet based site-to-site

Intranet and extranet based site-to-site are basically used for high business purposes whereas, Remote access for the individual ones and for small scale businesses.

What are the Protocols for Tunneling?
  • Open VPN– It is an open-source Virtual Private Network. It is constructed based on the traditional security type of protocols as of Secure Sockets Layer and Transport Layer Security protocols. It transfers data at low speed when compared to PPTP and IPSec.
  • SSH- This type of protocol uses SSH client, which generates tunnels to encrypt data commonly known as Secure Shell protocol.
  • SSL and TLS- Secure Sockets Layer and its later generation Transport Layer Security protocol are some of the protocols since the early days of VPN encryption. These are mostly used in e-commerce websites and applications. 03
  • PPTP- The point-to-point tunneling protocol is highly secured when compared with others. It is used to transfer data at high speeds.
  • L2TP- Layer 2 Tunnelling Protocol is slow in transferring data but highly secured when compared to PPTP.
  • IPSec- This type of protocol can be integrated with other security levels of protocols to ensure high security. It is used to ensure encryption of each data packet, with two modes one is transport mode and the other called tunneling mode. Internet Protocol Security is abbreviated as IPSec.

Transport mode is enabled for the encryption of information in each data packet whereas Tunnelling mode is used to encrypt whole data packets for ensuring security.

The security levels of protocols and types may vary. It can be chosen based on your needs. The theft could be often observable only your device gets accessed to the public networks. This public network could steal your credentials, including your credit and debit card details, your personal information to seek for money. This could result in eavesdropping your device. This encryption feature of a VPN could provide a solution.
