An Informative guide for VPN and VPN Protocols


The term "VPN" stands for virtual private network. This is a type of technology that establishes a secure network connection over a public network, like the internet, or even within a service provider's private network. The term "virtual" is used because this is not an actual dedicated connection—rather than getting a line that only you can use, you are borrowing bandwidth and space from someone else's internet connection. VPNs use a variety of protocols to encrypt and encapsulate your data, so you can be sure it will stay safe even if it passes through someone else's network. 

Various big organizations like cyber cell, national security agencies and schools use VPN for their different purposes. VPN is also used by big educational organizations so that their students in different campuses in different countries can attend the class at the same time.

 

In order to establish a VPN connection, there are several requirements. First and foremost, users need to provide credentials for authentication purposes, such as a username and password. Some VPN connections require a personal identification number (PIN), which can be found in the form of a token. The PIN is supposed to authenticate the identity of the user.


Once the authentication process has been completed, the user will be able to securely access their computer network through a VPN connection.


A virtual private network (VPN) is a service that protects your privacy when you connect to the internet by using security procedures and tunneling protocols. 


Today We Will Discuss Various VPN Protocols:


  1. Point to Point Tunneling Protocol(PPTP): 

The Point-to-Point Tunneling Protocol (PPTP) is a data-link layer protocol for wide area networks (WANs) based on the Point-to-Point Protocol (PPP) and developed by Microsoft that enables network traffic to be encapsulated and routed over an unsecured public network such as the Internet. It is considered as a less secure protocol because it use of 128 bits to encrypt traffic. 


  1. Layer Two Tunneling Protocol (L2TP): 

Layer 2 Tunneling Protocol (L2TP) is a data-link layer protocol that provides a secure tunnel between two points. It doesn't encrypt the data, but it adds a header to the packets to transmit them over an IP network. L2TP is usually used in combination with Internet Protocol Security (IPsec) for encryption and authentication, though it's possible to use L2TP alone.


The combination of the 3DES encryption algorithm and 168 bit keys are what make L2TP encryption more powerful.


  1. Secure Socket Tunneling Protocol (SSTP): 

One of the most secure VPN protocols is SSTP, or Secure Socket Tunneling Protocol. It is a SSL VPN protocol that uses 2048-bit encryption keys and authentication certificates.


The reason it is the most secure of all protocols is because it can operate even on network environments that block VPN protocols. Some countries like Belize do not allow the use of VPN connections, and there are certain companies that do this as well. VPN with SSTP protocol is useful for these types of situations.


Conclusion: 

VPNs are the latest technological tools that are highly regarded by netizens. They use Internet anonymization to grant access to content and information; however, the increasing number of users is creating difficulties in recognizing their advantages and disadvantages.
