Virtual Private Network is the way of creating the secured connection and based on the idea of tunneling. It mainly involves in the process of establishing and maintaining the logical network connection, then completely isolated from another network. Types of VPN services are business, governments, military organization to remotely use network resources surely. Accessing the sensitive information on remotely cannot be found without VPN; it is more affordable and much faster.
Types Of VPN
There are two main classes in VPN; they are client-based VPNs and network-based VPNs. These VPN types depend on certain VPN protocols; they are Internet Protocol Security, Layer 2 Tunneling Protocol, point to point tunneling protocol, Secure Sockets Layer, open VPN, and Secure Shell.
- Client Based VPN
The client based VPN is the private network created between a single user and remote system. It allows the users to connect to a remote network through the application. Most of the Windows, Mac, and mobile OS have the standard based VPN client options in it. It makes easier to stay connected with the laptops, iphone, ipad to get connected with headquarter in traveling. VPN clients often offer enhanced security features and carefully inspect the device. Cisco any connect client can verify the device has a particular version of anti-virus installed. Premium VPN clients come at licensing cost and typically authorized by the number of simultaneous VPN connections are allowed.
- Network-based VPN
Network-based VPN securely connect the two networks across the untrusted network. This protocol has the various kinds of VPN and three are the most important in them. They are IPSec tunnels both route and policy based dynamic multipoint VPN, and MPLS-based L3VPN. IPSec is the simplest approach to VPN, necessary to establish the endpoints of the tunnel. In the other way, this device is responsible for encapsulating and de- encapsulating the information in encrypted form. The Access control list provides Policy-based VPNs.
Types Of VPN Protocol
- Internet Protocol Security Or IPSec
It is mainly used to secure the web connection across the IP network by authenticating the session. Then it encrypts the each data packet during the connection. This is primarily the collection of multiple related protocols and exists at the network layer of OSI model. Internet Protocol Security has two important modes as tunneling mode and transport mode. These are mainly to protect the data transfer connection between the two different networks. The transport mode encrypts the message in the data packet, where the tunneling mode encrypts the entire data packet. This protocol can also be used with the other security protocol to augment the system.This article gives the entire detail about the types of VPN protocol.
- Layer 2 Tunneling Protocol (L2TP)
L2TP is the competitor to PPTP for VPN tunneling. This protocol is mainly implemented primarily in Cisco products and handles the secure connection between the tunnels. The two main components that make up L2TP are L2TP access controller and L2TP Network Server. The L2TP access controller is the device that physically terminates a call, where L2TP Network Server terminates and possibly authenticates the PPP system. It has the advantages of high security for critical applications, provides excellent and efficient connectivity, reliable, scalable, fast, cost-effective, flexible and much more.
- Point to Point Tunneling Protocol
This protocol is the most widely supported VPN method among the Windows users, and then it creates the tunnel and encapsulates the data packet. It is faster and available for Linux and Mac users. PPP is most widely used protocol since from the time of Windows 95. It supports the VPN connectivity across the local network and supports the two types of information they are control messages and data packets. The control messages use for managing and eventually tear down the connection, then pass directly between the VPN client and server. In the case of the data packet, it passes through the tunnel from or to VPN client.
- Secure Sockets Layer (SSL)
SSL is the VPN accessible through a web browser and not in need of any software to be installed. This protocol is mainly in online banking and payment gateways. It also creates the secure connection between the client system and host system. SSL precedes to Transport layer security (TLS), SSL initially connects with URL instead of HTTP.TLS is composed of two layers as TLS record protocol and TLS handshake protocol. TLS is most secure and efficient of message authentication with newer and reliable algorithms.
OpenVPN - Open Source VPN
It is the open source for creating the point to point and site to site connections. Open VPN is using all authentication, encryption, and certification features to protect t the private network traffic. This protocol provides many internal security features and runs a custom security based on SSL and TLS. It gets extended with the third party plugins, which calls at entry points. Gone through other secure VPN protocols and IPVanish review this are built for the user to enhance their skills.
Generally, in open VPN, the tunnel can be created and configured with the single command. It can read the certificate and private keys from the smart card which supports the Windows.
Secure Shell (SSH)
Secure Shell is mainly created and designed to provide the best security while accessing another computer along with the better authentication facilities. It eliminates every eavesdropping, connection hijacking, and from all other attacks. SSH consists of four tools they are the remote operations, key management, and the server side consists of sshd, ssh-agent and gets incorporated into many commercial products.
The main benefit of VPN is that, ensures the appropriate level of security to the connected systems. VPN has evolved to provide the same level of secure communication among any devices on the internet.
These are the different types of VPN which use a public infrastructure like the internet to provide users with the secure access to their organization network. In the upcoming days, VPN is becoming more popular among the consumers to protect their privacy online in the perfect way.
Types Of Vpn
It offers the better third party services for secure connections between the remote users and within the private network. Extranet-based VPN connects LAN to LAN between multiple companies and provides a lot of services.
