Design of IPSec virtual private network for remote access

摘要

The paper reports the design of an IP Secure Virtual Private Network (VPN) for remote access. The Cisco Packet Traces platform is used for the simulation, analysis and verification purpose. A VPN connects remote sites and users together using a public network, such as Internet. It uses virtual connection to route the data packets from a private network to remote sites or remote access users. It creates a tunnel between the end users to ensure security of data being transmitted over the Internet. The smart gadgets can be securely get connected with peripherals/users in the Internet as if they were part of same private network. In order to avoid any security attacks, a VPN need to be secured so as to prevent user data loss.
