1 Human Computer Interaction - Fall 2010 Class project By Khang Nguyen Virtual Private Network Design for Remote Access Cambridge - SFO Airport Test Site

2 VPN Concept VPN Benefit SSL SonicWall VPN-200 Case Study – SFO Airport Site Using VNC (Virtual Network Control) Conclusion Virtual Private Network Access for SFO Airport Lidar System

3 3 Institutions, companies often want private networks for security. – Costly! Separate routers, T1 links, DNS infrastructure. With a VPN, institution’s inter-office traffic is sent over public Internet instead. – But inter-office traffic is encrypted before entering public Internet Virtual Private Networks (VPNs)
