By Tunneling : Tunneling means to create a tunnel on the public network in which the whole packet is transmitted in another packet on the public network.  In this, the encapsulating protocol is selected in such a way that other computers or network devices cannot understand it while data is being transmitted over a public network.  Through encryption, we can scramble the data so that only the receiver can understand it. 

By Encryption: tunneling means to create a tunnel on the public network in which the entire packet is transmitted in other packets on the public network.  In this, the encapsulating protocol is chosen in such a way that the data cannot be understood by other computers or network devices while it is being transmitted over the public network. 

VPN (Virtual Private Network) Network Protocol

VPN Network Protocol

With the passage of time, some protocols and security features are also increasing, some of them are as follows – 

  • IP security: It is often used to secure the Internet connection. 
  • PPTP: Point-to-Point Tunneling Protocol is a technology used to create a VPN.  PPTP has been around since the time of windows 95.  The special thing about PPTP is that it is easily set up with every major operating system, but recently, many questions were raised about the security of PPTP.  PPTP is still strong but not completely secure.  It does not do encryption rather it only tunnels and encapsulates the data packets. 
  • L2TP: Layer 2 Tunneling protocol is a technology that is an extension of the PPP protocol that enables ISPs to operate VPNs. 
  • SSL (Secure Sockets Layer) and TLS (Transport Layer Security): SSL and TLS create a VPN connection where the web browser acts as the client and users have access to a specific application instead of accessing the entire network  .  SSL and TLS protocols are most commonly used by online shopping websites and service providers. 
  • SSH (Secure Shell): SSH is also known as Secure Socket Shell.  It is a network protocol that allows administrators to securely access remote computers.  Secure Shell enables strong authentication and encrypted data communication between two computers on an unsecured network such as the Internet. 
  • Open VPN : Open VPN is an SSL based VPN which is becoming very popular.  The software is freely available, SSL is a mature encryption protocol and OpenVPN can be run on a single UDP YA TCP port which makes it very flexible. 
  • L2TP/IP Sec: L2TP/IP Sec is more secure than PPTP.  To provide the best functionality, L2TP/IPSec implements two protocols together in which L2TP creates a tunnel and IPSec provides a secure channel.

Types of VPN (Virtual Private Network)

There are mainly three types of VPN, they are – Site-to-Site VPN, PPTP VPN, IPsec. 

  1. Site-to-Site VPN: While using this VPN, no dedicated line can be used in it.  In this, different sites of the same organization, each with its own network, are connected together to form a VPN.  Site-to-site VPN is almost the same as PPTP except for one thing.  Unlike PPTP routing, encryption and decryption are built into the router at both ends which can be hardware or software based. 
  2. PPTP VPN: PPTP stands for Point-to-Point Tunneling Protocol.  This is a very common and widely used VPN protocol.  Its disadvantage is that it does not provide encryption and users connect to the VPN network over an existing Internet connection, using password authentication over the VPN.  It does not require additional hardware and its features are often available as inexpensive add-on software. 
  3. IPsec VPN : It is a trusted protocol which setup tunnel from remote site to central site.  As its name suggests, it is designed for IP traffic.  IPSec requires costly, time-consuming client installations and is therefore considered its biggest disadvantage.
