What is VPN?
VPN or Virtual Private Network is a network technology that creates a secure network connection over a public network like the Internet. The computers and devices connected to the VPN allow them to transfer the data securely through the encrypted tunnels created by the VPN. All the network traffic is sent over a secure connection to the VPN, keeping the data and information safe and secure. Much like a firewall that protects the data on your computer, VPNs protect your data over the Internet.
VPNs are most often used by corporations to protect sensitive data. However, using a personal VPN is increasingly becoming more popular as more interactions that were previously face-to-face transition to the Internet. Privacy is increased with a VPN because the user’s initial IP address is replaced with one from the VPN provider.A VPN is designed to provide a secure, encrypted tunnel to transmit the data between the remote user and the company network. The information transmitted between the two locations via the encrypted tunnel cannot be read by anyone else because the system contains several elements to secure both the company’s private network and the outside network through which the remote user connects through.
PPTP – The Point-to-Point Tunneling Protocol is an obsolete method for implementing virtual private networks, with many known security issues. PPTP uses a TCP control channel and a GRE tunnel to encapsulate PPP packets
L2TP/IPsec – IPsec is often used to secure L2TP packets by providing confidentiality, authentication, and integrity. The combination of these two protocols is generally known as L2TP/IPsec
Open VPN – OpenVPN is an SSL-based VPN that continues to gain popularity. The software used is open source and freely available.
