VPN for Windows: Know What to Look For
There are two main VPN protocols that are commonly used for enterprise networking- Point-to-Point Tunneling Protocol (PPTP) and Internet Protocol Security (IPSec). PPTP was one of the first VPN protocols to be used for computer-to-computer or computer-to-server network communication. The main feature of PPTP is that it uses Virtual Private Network (VPN) architecture to provide security for data transmissions over an un-trusted network.
At the same time, IPSec is a standard for data encryption used in VPN and Virtual Private LAN Service (VPLS) networks. The difference between PPTP and IPSec protocols is that PPTP is not as secure as IPSec and can be hacked easily. On the other hand, IPSec is very secure and is not hackable. However, the most widely used VPN protocol is IPSec because it is more secure and reliable than PPTP.
Authentication – Authentication protocols verify the server and user credentials to ensure that they are authorized to access the server. Password Authentication Protocol (PAP) is one of the most common authentication protocols used in the early days of the internet. PAP is now considered vulnerable, so it is better to avoid PAP when selecting a VPN. – Encryption – Encryption protocols are used to encrypt data and transform it into a format that can only be deciphered by authorized parties who are connected to the VPN network.
