The Ultimate Guide for Virtual Private Network

A Virtual Private is a technology creating a connection that is secure and encrypted over a less protected network like the internet. It was developed as a method for enabling the users and branch offices to access the corporate-related applications securely including other resources. It is imperative for the user of VPN that he/she should use the strong security methods for ensuring the safety and data travels through secure tunnels. Users can include security methods like tokens, passwords, and other procedures of identification for gaining access to the server or virtual private network.

Virtual private networks are used by the remote workers who require access to the corporate assets, customers who intend for downloading the files and travelers of business who requires logging into the sites which are geographically restricted.

How VPNs works?

The two main types of VPNs include the remote access and site-to-site. Conversing about the remote access then it integrates the use of telecommunication infrastructure for providing secure access to the remote users to the network of an organization. The users or employees can make use of this type during the use of public Wi-Fi hotspot.

For securing the connection remote-access VPN dependency is on the IP Security (IPsec), Secure Socket Layer (SSL).

On the other hand, site-to-site VPN includes the use of gateway device for connecting the network in one location to a network.

The gateway can handle the connection itself, so there is no need of VPN clients for the end-node devices in the remote location. Most of the site-to-site VPNs make use of the IPsec, and it is usual for them for using the carrier MPLS clouds.

VPN Protocols

The Virtual Private Network characterizes how service manages the transmission of data over a VPN. The common protocols of VPN include PPTP, SSTP, IKEV2, and OpenVPN.

PPTP

Point-to-point tunneling protocol or PPTP is one of the oldest protocols that are in use. Microsoft developed this protocol. The benefit of using this protocol is that it works on old computers and is the windows operating system part. Settling this protocol is also very simple.

L2TP/IPsec

Layer 2 tunneling protocol or L2TP is the PPTP and Cisco’s L2F protocol combination. This is a sound protocol and makes use of the keys for establishing the protected connection on every end of the data tunnel. The only issue is that the execution is not secure.

SSTP

The Microsoft also designed secure socket tunneling protocol or SSTP and the connection is settled with the encryption that is SSL/TLS. The strength of this encryption is built on the cryptography that is symmetric-key.

OpenVPN

It is a protocol and is based on SSL/TLS encryption and is an open source project. This protocol protects the connection by using the keys which are recognized by the two parties on the transmission end. It is one of the best, versatile and protected protocols.
