  1. VPN Protocol

  2. VPN VPN What is a VPN? • A VPN is A network that uses Internet or other network service to transmit data. • A VPN includes authentication and encryption to protect data integrity and confidentiality Internet

  3. VPN Protocol • Virtual private network (VPN) protocols are a group of transmission control protocol/internet protocols (TCP/IPs) that enable the safe transfer of data over the Internet. A VPN is a network of computers that allows its users to connect to the Internet. • protocol is a set of standardized rules that determines error detection methods, data authentication, signaling and representation of data over a communications channel---the medium used for the transfer of data from the sender to the receiver. Its purpose is to ensure a reliable channel for the exchange of data.

  4. PPTP • PPTP (Point to Point Tunneling Protocol) is a good, lightweight VPN protocol offering basic online security with fast speeds. PPTP is built-in to a wide array of desktop and mobile devices and features 128-bit encryption. PPTP is a good choice if OpenVPN isn't available on your device and speed is top priority.

  5. Internet Point-to-Point Tunneling Protocol (PPTP) • Layer 2 remote access VPN distributed with Windows product family • Addition to Point-to-Point Protocol (PPP) • Allows multiple Layer 3 Protocols • Uses proprietary authentication and encryption • Limited user management and scalability • Used MPPE encryption method Corporate Network Remote PPTP Client PPTP RAS Server ISP Remote Access Switch

  6. L2TP/IPsec • L2TP (Layer 2 Tunneling Protocol) with IPsec (IP Security) is a very secure protocol built-in to a wide array of desktop and mobile devices. • L2TP/IPsec features 256-bit encryption, but the extra security overhead requires more CPU usage than PPTP. L2TP/IPsec is an excellent choice if OpenVPN is not available on your device, but you want more security than PPTP.

  7. Internet Layer 2 Tunneling Protocol (L2TP) • Layer 2 remote access VPN protocol • Combines and extends PPTP and L2F (Cisco supported protocol) • Weak authentication and encryption • Addition to Point-to-Point Protocol (PPP) • Must be combined with IPSec for enterprise-level security Corporate Network Remote L2TP Client L2TP Server ISP L2TP Concentrator

  8. Internet Protocol Security (IPSec) • Layer 3 protocol for remote access, intranet, and extranet VPNs • Internet standard for VPNs • Provides flexible encryption and message authentication/integrity

  9. OpenVPN • OpenVPN is the premier VPN protocol designed for modern broadband networks, but is not supported by mobile devices and tablets. OpenVPN features 256-bit encryption and is extremely stable and fast over networks with long distances and high latency. It provides greater security than PPTP and requires less CPU usage than L2TP/IPsec. OpenVPN is the recommended protocol for desktops, including Windows, Mac OS X, and Linux.
